1. low friction coefficient
2. Able to move in both radial and axial directions
3. High precision, working in high speed
4. Different specs ,also can manufacture upon request
5.It can decrease fatigue damage causing by rolling contact and side damage on machine parts and prolong service life.
6.sound quality steel ball retainer with excellent performance of hardness,glossiness,buildiness,abrasion resistance,long service-life.
The bushing has 3 types,which is made of steel( it can made of other material ,just like ceramic,plastic etc.)
