Installation and adjustment with high speed bearings

When the co-ordination and high speed bearings clearance due to the rapid bearing both high precision bearings according to requirements, but also according to the requirements of high temperature bearings, so consider the mating and clearance, to take into account the following points:
(1) changes in the size and hardness changes in temperature rose at a high temperature;
(2) High speed centrifugal force caused by the force system changes and shape changes.
In short, at high speed, high temperature conditions, with and clearance from the choice you want to strive to maintain the accuracy and performance of the bearing, which is difficult. In order to ensure the installation of the rear bearing raceway deformation is small, angular contact ball bearing interference fit the amount of interference can not achieve much, but heat and centrifugal force at high speed under high temperature expansion, surface or offset with normal pressure. Or the mating surface relaxation, and therefore the amount of
interference must be carefully applied in consideration of the above two factors premise In computing, at normal temperature and normal speed under effective amount of interference for high-speed bearings may be invalid.

How to prolong the life of the bearing flange

Workaround miniature bearings when overheating

Because of different reasons miniature bearings fever, so to solve in different ways, the following are workarounds for miniature bearings overheating when:
1, filling fat law, so-called fat method is to fill the bearing surface regularly to fill the right amount of grease, is one of the most commonly used grease lubrication.
2, oil cup oil cup method is to set the cap-type oil cup or mug oily pressure in the bearing housing, periodically rotating the cap or oil gun grease injection. This is also a common grease lubrication.
3, the pressure for fat method, pressure method is to rely on fat for the grease pump for grease. You should choose good mobility grease.
4, centralized method for fat, centralized method for grease through grease pump, simultaneously to various deep groove ball bearings and other parts for fat. Similarly, when the flow of grease should be used in offerings and good resistance to oxidation and corrosion resistance of the grease,It is also a method for grease pressure.

Miniature Bearing Failure

About the failure of miniature ball bearings in the 40% by dust, dirt, debris and pollution caused by corrosion. Pollution is usually caused by improper use and poor use of the environment, it can also cause problems torque and noise. Miniature Bearing failures and pollution generated by the ring is preventable, and by simple visual observation can determine the cause of this type of failure. As long as a reasonable use and install, miniature bearings are easy to avoid the erosion. Erosion is characterized in miniature bearing ring raceway indentations left by the impact load or incorrect installation generated. Erosion usually occurs when the load exceeds the material yield limit. If not properly installed so that a load across the miniature bearing ring will produce erosion. Indentation will be miniature bearing ring on noise, vibration and additional torque.

Linear plain bearings and plastic linear bearings

Linear plain bearings are linear locating bearing unlimited stroke length. These linear guidance systems Miniature plain guidance system may be, Permaglide linear plain bearings and Permaglide linear plain bearing units as well as flat guidance system. Plastic linear bearing is a self-lubricating properties of linear motion system, the biggest difference is the metal with the metal linear bearings linear bearing is rolling friction, is the point of contact between the bearing and the cylinder axis, so this is suitable for low load speed movement; and plastic linear bearings are sliding friction, it is surface contact between the bearing and the cylinder axis, so this for high-load low-speed movement.

Linear motion bearings

Linear motion bearings is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Since carrying the ball point contact with the shaft, so the use of small load. Minimal friction ball rotation, which can get high-precision smooth movement. In the rolling bearing, the bearing ring is rolling unit (rolling elements) apart, in plain guidance systems the movable part of the slide in a static rail or shaft. Depending on the type of track system, the sliding layer on a movable or rigid good components. Lubricating sliding layer embedded to achieve lubrication purposes.

Linear bearing

Linear bearing is a linear motion system for linear travel with the cylinder axis. Since carrying the ball point contact with the bearing housing, the ball rolling with a minimum of friction, and therefore has a small friction linear bearings, and relatively stable, with the bearing speed change, can achieve high sensitivity, high accuracy smooth linear motion. Linear bearings consumption also has its limitations, the most important is the impact of poor load bearing capacity, and the carrying capacity is also poor, followed by linear bearings in large high-speed motion vibration and noise. Linear bearings quick and easy selection have included gifted automation. Linear bearings are widely applied to the sliding parts precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery. Since carrying the ball in contact with the bearing point, so the use of small loads. Minimal friction ball rotation, which can get high-precision smooth movement.

The more contact, more and more even, said sliding bearing scraping the research better, on the other hand, sliding bearing scraping the inquiry is not good. In general the more the more close contact point, research difficulty is large. Production should be based on the performance of the sliding bearing and working conditions to determine the contact point

The linear plain bearings grease lubrication cycle:

By accident, linear plain bearings not important parts: shaft speed < 200 r/min, the lubrication cycle 5 days; Shaft speed > 200 r/min, the lubrication cycle 3 days.

Continuous work: shaft speed < 200 r/min, the lubrication cycle 2 days; Shaft speed > 200 r/min, the lubrication cycle 1 days.

Continuous work, operating temperature less than 40 ℃ : shaft speed < 200 r/min, the lubrication cycle 1 days; Shaft speed > 200 r/min, the lubrication cycle once per class.

Continuous work, operating temperature 40-100 ℃ : shaft speed < 200 r/min, the lubrication cycle per shift once; Shaft speed > 200 r/min, the lubrication cycle every second.

The journal as uniform close contact with mobile crane bearing, and must fit clearance.

Refers to the journal and sliding bearing contact area of the central Angle. Contact Angle is not too big nor too small. Contact Angle is too small will make sliding bearing pressure increases, serious when they make the sliding bearing produces large deformation, accelerate wear, shorten service life. Contact Angle is too big, can affect the formation of oil film, can't get good fluid lubrication.

Solution of miniature ball bearings overheating temperature

Because of the different heating reason of miniature ball bearings, the solving way is different, here is a method of solution for the miniature bearing overheating temperature.

• Filling grease method, the so-called filling grease method is regularly to the working surface of the bearing to fill in the amount of grease,which is one of the most commonly used grease lubrication way.

• The oil cup method, the oil cup is arranged in the bearing seat by screw cap type oil cup or pressure oil cup, periodically rotating the cover or using a gun will grease injection. It is also a common way of lubricating grease

• The pressure for fat method, thin section angular contact bearings pressure grease method is to rely on the lubricating grease pump grease. You should use grease with good fluidity.

• Centralized grease, centralized grease through the grease pump method, at the same time for the fat to each deep groove ball bearings and other components.

  Meanwhile,thin section bearing at this time the grease should use of lubricating grease flowing sacrifice, good oxidation resistance and corrosion resistance,which is also a kind of pressure for fat method.

The big three models of flange bearings

Since flange bearing are designed to increase  accuracy of position, there are thousands and hundreds models availability.Each designed for applicability of particular ball bearing functions and requirements.
When selecting a high speed bearing, the dimensions should suit the diameter of the shaft, and they are thus available in a myriad of sizes. The largest differentiating factor between flange bearings is the number of bolts (mounting holes) on the mechanism.
Double-bolt flanges
These flanges are available either in a wing-shape or in a diamond shape, which have two mounting holes, (usually elongated for simple, user-friendly adjustment). They are engineered to be repositioned and aligned for the best fit of shaft
Three-bolt flanges,these flanges are round, which have three equidistant mounting holes.
They are engineered to be repositioned and aligned for the best fit of shaft.

Four-bolt flangesThese flanges are square shaped, which have four equidistant mounting holes. For the larger number of positioning bolt-holes, they are more stable than their double-bolt counterparts,thus have a greater load-capacity. They are engineered to be repositioned and aligned for best fit of shaft.

  Flange linear ball bearing often made from cast iron or thermoplastic material. But some manufacturers produce flange bearings of  plastic. The polymer bearings offer a more cost-effective option to metal flanges. They are backed by a thin construction to compensate for the lost width,maintaining the stability and temperature resistance offered by their metal counterparts.

Motion mechanism of flange bearing

Flange bearing especially engineered to provide a precise mounting fit for ball bearing,which executed through axial location of the bearings' shaft ends, stabilizing the position of bearings and consequently maximizing the load support. When utilizing a miniature ball bearing where the shaft axis is perpendicular to the mount, flange bearing facilitate rotary or linear movement.
There are many kinds of flanges, whose designs and  cages are engineered to suit their corresponding ball bearings. in order to optimize their loading and speed capacities, allow the two devices to function in accordance. The flange bearing is screwed in relation to the shaft axis. Thus the mechanism is comprised of an insert attached to a relatively flat housing structure.
Flange bearing is usually equipped with  easily install spherical ball that offers a pivoting angle so as to relieve misalignment. The characters of bearing are  highly sturdy, maintenance-free, dirt-resistant, water-resistant, and able to adapt to an array of room temperatures.

LYHY miniature ball bearing

A ball bearing can be highly effective at reducing friction between two parts that need to move freely. There is some elasticity to the ball allowing it to support and move a range of bearing loads.
Naturally, the balls in such bearings come in a variety of different sizes, from fairly large to miniature. Small Bearings can be extremely useful in applications where space is limited, such as automotive, electrical  and medical devices.
LYHY Miniature ball bearings afford you wide variety of miniature bearings means that you are certain to find just the bearings you are looking for. Use the bearings search fields to find the bearings you need. Search by bearings size according to inch or metric measurement and by inside diameter size and outside diameter size.

Tips for miniature bearing heating

• the yoke placed  on the end face of the host .

• insert the plug into a power socket with switches.

• check the grounding wire, after the power is switched on with the test pencil test.

• press the start button, the main power switch.

• check the yoke to ground shall be voltage free.

• press the stop button to stop the host power, heating.

• according to the linear ball bearing with different specifications or other workpiece, choosing different sets of the yoke, the yoke on the top surface of the host,  should be smooth.

• heating high speed bearings , the sensor should be inserted into the Sensor Socket, and will be close to the workpiece is heated sensor.

The failure reason of miniature bearings

The failure of the ball in the flanged ball bearing in about 40% are caused by dust, dirt, debris pollution and corrosion. Pollution is usually caused by incorrect use and poor use environment, it also causes torque and noise problems.
Miniature ball bearings produced by the environment and pollution of the failure can be prevented, and observed by the naked eye is simple can determine the production of this kind of failure reason. As long as the use and reasonable installation, denudation of miniature bearing is easy to avoid. Erosion is characterized in miniature bearing ring raceway on the left indentation produced by impact load or incorrect installation.
Erosion is usually occurs in the load exceeds the yield limit of material. If not installed correctly so that a load across the miniature bearing ring will produce erosion. Miniature bearing ring on the pressure pit will produce noise, vibration and the additional torque.

Application of miniature bearing

Miniature ball bearings are suitable for all kinds of industrial equipment,  small rotary motor high speed bearing low noise field, such as,

  Office equipment, micro motor, instrument, laser engraving, small clock, soft drive, pressure rotor, dental drill, the hard disk motor, stepping motor, VCR drum, toys, computer cooling fan, currency-counting machine, fax machine and so on related field.

Miniature bearings

Miniature bearing refers to  all kinds of bearings,whose outside diameter less than 9mm of  metric series and outside diameter less than 9.525mm of inch series. The main materials are steel, bearing steel, stainless steel, plastic, ceramic, wherein the inner diameter of the smallest can do 0.6mm, with more 1mm inner diameter.

  In the miniature bearing of ultra small aperture, types of miniature deep groove ball bearings are metric 68 series, 69 series, 60 series, a total of 6 inch R series.On this basis,angular contact ball bearing also can be divided into with ZZ steel dust cover bearing series, with RS rubber sealing ring for miniature bearing series, teflon bearing seal ring series and with flange rib series and so on.

Flanged ball bearing show

Many miniature ball bearings have flanges as options to their configurations. The flange is designed for mounting and positioning,which is especially true for miniature and instrument bearings and applies to other ball bearing types.

Relevant parts of requirements of the high speed bearing host

Rotating system of high speed bearings  require  precision dynamic balancing.Installation bearing part of shaft and hole  is higher than the general requirements for the dimensional accuracy and the position accuracy .

  LYHY bearings, especially the verticality of coaxiality and shoulder block seat hole or shaft neck, and in consideration of these problems, we must  pay attention to the high speed factors bearing in operation and high temperature factor.

  Shaft bearing system requires high rigidity,  as far as possible the light quality. In order to overcome this contradiction,we can  take measures  to improve the supporting stiffness ,such as reducing the surface roughness and improving the surface strengthening  , or using  hollow shaft to reduce the quality of the system etc.
