Bearing material structure characteristics

Plastic bearing materials high-performance engineering plastics as the base material is mainly used as wear resistance carrier;
Reinforced fiber improves bearing capacity and impact resistance.
Special greases reduce the friction coefficient of bearings and play a self-lubricating role.

Principle of friction and wear of plastic bearings

As long as any self-lubricating bearing works under load, the bearing will produce subtle friction damage. T series bearing the same is true of, the start stage when wear occurs grease will seep gradually fill the friction surface and transferred to the friction surface when the grinding shaft work area filled with grease and then form a very thin layer of isolation film, the bearing of the initial wear almost end, bearing in the later work long hours of wear rate is greatly reduced and the stability.

 

Bearing wear

Because the wear resistance of bearings is affected by many factors, it is difficult to accurately describe the wear and life of bearings. Through countless experiments show that the factors of wear resistance and life of ring bearings are: load, speed, mode of movement, shaft material and roughness, ambient temperature and dust, external lubrication medium type and so on. The wear resistance of bearings generally decreases gradually with the increase of load, speed and temperature. When there is external lubricating medium, the wear resistance of bearings will increase exponentially.
We recommend that the roughness of the shaft is RA0.2-RA0.8. Too rough or too smooth will lead to aggravated wear. Too rough will scratch the friction surface of the bearing like a scraper, and too smooth will glue the friction surface and the bearing surface, resulting in increased wear.
There is no special limit for T series bearings of shaft materials. However, since various shaft materials have different effects on bearing wear, we recommend the use of a more general surface hard chrome plated shaft material, and there is no limit on the hardness of the shaft. We recommend the use of shaft materials above HRC35 to avoid shaft wear in the initial working stage of the bearing.

Bearing assembly

T series plastic bearings with a hole material with no restrictions, but must be a hole end chamfering 25 ° to avoid bearing pressure fashionable scratch outside diameter, pressure equipment should be used when the ladder slowly pressed into the core axis, banned direct strike ends, in order to avoid deformation, affect the bearing size T series products inside diameter tolerance is pressed into the H7 standard hole after you get.

 

Shaft: T series plastic bearing with shaft material is not specific, but we recommend chrome hard shaft. In order to make the shaft more simple in the assembly process and not damage the bearing internal friction surface, the end face of the shaft must have a chamfered smooth transition. In addition, the surface roughness of the shaft has a great influence on the friction coefficient of the bearing, and the friction surface of the shaft is too smooth to produce creeping phenomenon or squeal. Too rough shaft surface will accelerate bearing wear. We recommend that the surface roughness of the shaft be RA0.2-RA0.8. Although the series of products are designed as self-lubricating products, applying an appropriate amount of external lubricant (such as grease) on the friction surface during assembly will shorten the running-in period of the bearing so as to extend the service life of the bearing.

 

Chemical resistance,

T-type plastic bearings can better resist weak acid and alkaline chemistry and hydrolysis, and resist corrosion of various lubricating oils.
