Don't miss the core OEM technology video of Auto bearings,

 released by DYS for the first time!

For the first time, DYS technical team explained to customers by video :
The core technology in OEM matching of automobile tension wheel bearing.
Please pay more attention！

Tightening wheel of automobile bearing (1): Selection of bearing (DK Series) 

 

DK series bearings developed and produced by DYS are mainly used on the plastic wheel 

of tensioner and on the idler gear of the tensioner .

 DK means that there is a knurled groove on the outer diameter of the bearing, 

it can effectively solve the looseness and slippage between the plastic wheel 

and the outer diameter of the bearing caused by the heat expansion in the operation, 

It also can prevents the axial movement of the bearing after the plastic thermal expansion at high temperature.

Tightening wheel of automobile bearing (2): Selection of bearing cage 

The speed of the Tightening wheel is not constant, 

which changes rapidly with the engine running between 4000-12000rpm, 

which requires a cage that can withstand the impact of steel ball due to rapid speed change. 

The new PA nylon cage developed by DYS can prevent cage deformation, 

increase oil storage space and prolong bearing’s service life.

(iron cage: when the steel ball collides with the iron cage due to rapid speed change, 

resulting the cage in deformation and seizure, or due to cage deformation, 

the steel ball is stuck in heat expansion during operation, and the bearing fails.)

Tightening wheel of automobile bearing (3):Bearing sealing structure

The sealing structure of the tension wheel bearing has very high requirements, 

not only to ensure that the dust in the external environment does not enter, 

but also to prevent grease leakage under high-speed and high-temperature operation, 

and determines the service life of the tensioning wheel.

 

Based on 20 years of deep groove ball bearing research and development experience, 

DYS has improved the design of bearings  inner ring, seal ring lip, 

contact amount and pull-out force and so on, 

which can effectively prevent the bearing sealing ring from falling off and leaking grease in injection molding, 

and prolong the service life of tensioning wheel.
