Overview

Single direction thrust ball bearing with sphered housing washer

Single direction thrust ball bearings, with sphered housing washer, can accommodate axial loads in one direction. They must not be subjected to any radial load. Many of the components are interchangeable. The shaft washers have a ground bore that enables an interference fit. The sphered housing washers can accommodate initial misalignment when configured correctly with a sphered seat washer or a machine component with a sphered surface.

Key features

Separable design facilitates mounting/dismounting and maintenance inspections
Interchangeable components
Ground bore of shaft washers enables interference fit
Sphered housing washers can accommodate initial misalignment

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.
