Overview

Single direction thrust ball bearing

Single direction thrust ball bearings can accommodate axial loads in one direction. They must not be subjected to any radial load. Their separable components facilitate mounting/dismounting and maintenance inspections. Many of the components are interchangeable. The shaft washers have a ground bore that enables an interference fit.

Key features

Separable design facilitates mounting/dismounting and maintenance inspections
Interchangeable components
Ground bore of shaft washers enable interference fit

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.
