Overview

Super-precision single direction angular contact thrust ball bearing

These 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. They provide a high degree of axial stiffness and can accommodate heavy axial loads in one direction, high speeds and rapid accelerations.

Key features

Very high running accuracy
High axial stiffness
High axial load carrying capacity in one direction
Universally matchable
Well suited for screw drive applications

Typical applications

Vertical motors and pumps
Rotary tables
Screw jacks and lifting devices
Low- to medium-speed axial support positions

Selection guidance

Verify axial load direction, speed, washer type, mounting face squareness, and whether any radial load is present.
