Linear ball bearings are a crucial component of any linear guidance system. They enable smooth, precise, and failure-free motion along precision shafts, while minimizing friction and component wear.

All dimensions in the table are in [mm], unless stated otherwise.
*Load capacity values are given for hardened and ground precision shafts (min. 59 HRC)
*For precision linear shafts of lower hardness, the effective load capacitied equal:
- for WRA: Cef = 0,74·C Coef=0,8·Co
- for WRB: Cef = 0,63·C Coef=0,7·Co
