LYHY flanged ball bearing How to prolong the service life of the bearing flange
Whether buyers or sellers are concerned about the length of life of the bearing. Such as: flange bearings mainly bear radial load, but also to support radial double row ball slewing bearing and axial loads flanged ball bearing. But for the life of the bearing flange are not very understanding, the following three steps will teach you to extend bearing life:
(1) In order to make the radial clearance between the bearing retainer and the bearing ring is provided with greater eccentricity than the internal structure has been improved;
(2) using the FEM analysis, by optimizing the shape and thickness, etc., to improve the strength of the retainer;
(3) In order to prevent a decrease in surface flanged ball bearing damage caused by the lubricating oil in the bearing ring in the design of the guide groove.

miniature ball bearings Wheel bearing (hub bearing)
Wheel bearing (hub bearing) primary role is to load and for the rotation of the hub to provide accurate guidance, both axial load and radial load, is a very important component. wind power bearing Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust the clearance is carried out in the car on the production line. This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also the need for bearing cleaning, oiling and adjustment. Developed on the basis of the hub bearing unit is the standard angular contact ball bearings and tapered roller bearings on, it will be two sets of bearings as a whole, with good assembly performance can be omitted clearance adjustment, light weight, Thrust Roller Bearings compact structure, load capacity large, sealed bearings can advance into the grease, hub seals and maintenance advantages omitted from the outside wheel, has been widely used in cars, and in the truck also has a tendency to gradually expand the application.

LYHY flanged ball bearing Installation and Use
Car wheel bearings are used in pairs over a maximum single row tapered roller or ball bearings. With the development of technology, the car has been widely used car wheel unit. The growing scope and use of hub bearing unit, has now developed to the third generation: the first generation is composed of ball and roller combined bearing a double row angular contact bearings. The second generation of the outer raceway for bearing a fixed flange ball bearing sleeve may simply be fixed with a nut on the axle. Makes the car maintenance becomes easy. The third generation wheel hub bearing units are using a bearing unit and ABS anti-lock brake system compatible. Wheel hub unit designed to have the inner flange and an outer flange, the flange is bolted to the drive shaft, the outer flange of the bearing mounted together. Worn or damaged wheel bearing or hub units will happen to your vehicle anachronistic and higher cost of failure in traveling the road, or even damage to your safety. Wheel bearings in use and installation Please note the following:
1, in order to ensure maximum safety and reliability, it is recommended that you no matter how long the age of the vehicle should always check the wheel bearings - note bearing for wear mobile crane bearing early warning signals: including any friction noise when rotating or turning wheel suspension combination when the deceleration is not normal. Rear-wheel drive vehicle is recommended for the vehicle to 38,000 km is to deal with the front wheel hub bearing lubrication. When replacing the brake system, check the bearing and replace the seal.
2, If you hear noise emitted wheel bearing parts, first of all, it is important to find the location of the noise occurs. There are many moving parts may produce noise, but also may be some rotation member and the rotating member occurs without contact. If the confirmation is bearing noise, bearing may be damaged and need replacing.
3, because the front wheel bearing failure on both sides led to similar working conditions, so even if only one bearing bad, it is recommended to replace in pairs.
4, wheel bearing more sensitive, in any case need to adopt the right approach and the right tools. In storage and during installation, the bearing parts can not be damaged. Angular contact ball bearings Requires a large number of bearings pressed into the pressure, so the need of special tools. Be sure to reference vehicle manufacturers instructions.
5, the installation of the bearing should clean environment, small particles from entering the bearing will shorten bearing life. When replacing bearings to maintain a clean environment is very important. Allowed to tap with a hammer bearing note bearing not fall to the ground (or similar improper handling). Before installing the shaft and the bearing housing should also check the condition of even a small amount of wear can also lead to poor fit, thereby causing early failure of the bearing.
6, on the wheel hub bearing unit, do not attempt to disassemble or adjust the wheel hub bearing seals unit, otherwise it would cause water damage to seals or dust from entering. Even ring and inner ring raceway are damaged, resulting in permanent failure of the bearing.
7, the ring is equipped with ABS unit has a magnetic thrust bearing ring, which thrust ring can not be a collision, impact or collision with other magnetic field. Remove from the box before wind power bearing installation, so that they stay away from magnetic fields, such as the use of electric motors or electric tools. When installing these bearings, the road test by observing the dashboard ABS alarm pin to change the bearing operation.

high speed bearing 3 Maintenance Note
1.equipped with ABS wheel hub bearing magnetic thrust ring, thrust ring mounted in order to determine which side, you can use a small light near the edge of something * high speed bearings, magnetic bearings will be attracted by it generated. When installing a magnetic thrust will take the side of the ring pointing inside, is on the ABS sensor. Note: Incorrect installation may lead to functional brake system failure.
9, many of the bearings are sealed, this type double row ball slewing bearing of bearing is not needed throughout the life of the grease increases. Other non-sealed bearings such as double row tapered roller bearings in the installation must be added grease. Because different lumen size of the bearing, it is difficult to determine how much of the added fat, the most important thing is to ensure that the grease bearing if too much fat, when the bearing is rotating, the excess oil will bleed. General Experience: During installation, the total amount of oil to account for 50% of the bearing clearance. 10, install the lock nut due to the different types of bearings and bearing housings, the size difference between the torque is great.
In the repair process, often found that some cars have a greater driving noise, no abnormal tire wear inspection, turn the wheels on the lift no abnormal sound. This phenomenon is often caused by abnormal wheel bearing damage caused by the so-called non-normal means of bearing damage caused by the installation ball and roller combined bearing of. Automotive wheel bearings are generally double row ball bearing, at the time of installation of the bearing installation if you use a hammer percussion, or when the bearing is installed into the bearing inner race of the bearing by pressing installed, will cause one side of the bearing raceways damage. Noise when the vehicle is traveling, and when the wheelie is better since the raceway side, and therefore noise was heard. Correct installation operation is the key to long life bearings.

miniature ball bearings Precision bearings distinction
Precision bearings and plain bearings should be used to distinguish between the following points:
1, the size of the required value is not the same, high level of accuracy of the product of its size deviation (inside diameter, outside diameter, oval, etc.) than the fine
Value of the low level of product requirements to be smaller;
2, rotating accuracy requirement values self aligning ball bearings are not the same, high level of accuracy of the product of its rotational accuracy (internal diameter of the beating, beating the outer diameter of the end face of the raceway beating, etc.) than the value of the low level of precision to be strict product requirements;
3, the surface shape and surface quality requirements values are not the same, high level of accuracy of the product on its surface shape and surface quality (or channel raceway surface roughness, circular deviation, ditch-shaped deviation) than the low accuracy level the value to be strict product requirements;
4, the accuracy of its products particularly high grade material than the material properties of the general levels of precision products more favorable.
Precision bearings in accordance with ISO double row ball slewing bearing grading standards are divided into:. P0, P6, P5, P4, P2 successively higher grades, where P0 is the general accuracy and precision are other grade levels. Of course, different classification criteria, different types of bearings, their method for classifying different, but the meaning is the one to. Performance requirements on the use of precision bearings rotating body with high runout accuracy, high-speed, low friction and friction change.
