6908 rs bearing features:  
In order to obtain low friction torque, high rigidity and good rotary precision of 6908 rs bearings, steel balls with small outer diameter are used.  The use of hollow shaft ensures lightweight and wiring space.  Thin-walled bearing 6908 rs has achieved extremely thin bearing section, and also achieved miniaturization and lightweight of products.  

6908 rs bearing
The diversity of products expands the range of uses.  
Thin-wall 6700, 6800 series have a variety of dust cover form, with flange form, stainless steel form, wide form, complete varieties.  
Lubrication purpose of 6908 rs bearing:
The purpose of lubrication of rolling bearing 6908 rs is to reduce the internal friction and wear of bearings and prevent burning. Its lubrication effect is as follows.  
Reduce friction and wear  
In the contact part of the bearing ring, 6908 rs rolling body and retainer, prevent metal contact, reduce friction and wear.  

6908 rs
The rolling fatigue life is extended when the rolling contact surface is well lubricated during rotation.On the contrary, low oil viscosity, lubricating oil film thickness is not good, it is shortened.  
The heat of friction is discharged and cooled  
Circulatory oil feeding method can be used to discharge heat from friction, or from the outside heat, cooling.  Prevent bearing overheating, prevent lubricating oil itself aging.  
It also has the effect of preventing foreign matter from invading into the bearing interior, or preventing rust and corrosion.
