Thrust Ball Bearings

Thrust ball bearings use a ball-and-cage assembly between a shaft washer and a housing washer to support axial loads with low friction.

BWK supplies single-direction thrust ball bearings in multiple metric series for compact industrial assemblies. Their separable structure makes installation, inspection and replacement straightforward.

Key Advantages

1. Stable Axial Support
Designed to carry axial loads in one direction.

2. Low-Friction Operation
Ball contact supports smooth and efficient rotation.

3. Separable Structure
Washers and cage assembly can be mounted separately.

4. Multiple Metric Series
Available for different bore sizes and load requirements.

Available Series

Series	Structure	Main Features
511 Series	Single-direction, light series	Compact section for general axial-load applications
512 Series	Single-direction, medium series	Higher load capacity with a wider section
513 Series	Single-direction, heavy series	Suitable for heavier axial loads
514 Series	Single-direction, extra-heavy series	Increased axial capacity and rigidity
