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.
