Super-precision sealed single direction angular contact thrust ball bearingThese sealed super-precision ball bearings offer very high running accuracy and are well suited for screw drive applications. They are also beneficial in other applications, where safe radial and axial support is required, together with extremely precise axial guidance of the shaft. Under normal operating conditions, sealed bearings are almost maintenance-free, keeping service costs and grease consumption low.
- Very high running accuracy
- High axial stiffness
- High axial load carrying capacity in one direction
- Universally matchable
- Well suited for screw drive applications
