Overview
Thrust ball bearing
Thrust ball bearings consist of balls and washer-shaped raceway rings and support axial loads only. Single-direction types take axial load in one direction, double-direction types in both; they do not carry radial load. They are used in machine tools, jacks and rotary tables.
Key features
- Dedicated axial load support
- Single- or double-direction types
- High axial rigidity
- Carry no radial load
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.
