Overview
NTN 5306C3 Thrust Ball Bearing is designed specifically to support axial load with a simple, low-friction structure. It is suitable for vertical shafts, rotary tables, jacks, and low- to medium-speed equipment where axial load control is more important than radial load capacity.
The bearing consists of shaft washer, housing washer, and ball-and-cage assembly. Single-direction types support axial load in one direction, while double-direction types support axial load in both directions; they are not intended for radial loading.
Key features
- Dedicated axial load support
- Simple structure with low friction
- Single- and double-direction designs
- Separable components for easy mounting and inspection
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.
