Single direction thrust ball bearings (511, 512, 513, 514 series) are designed to support axial loads in low-speed industrial rotating systems. They provide stable performance, high precision and long service life under continuous load conditions.
Key features include:
- Designed for unidirectional axial load support
- High precision steel ball and cage structure for stable operation
- Suitable for low-speed, heavy-duty industrial equipment
- Available in small to extra-large diameter ranges
Applications
- Machine tools: vertical lathes, drilling and boring machines
- Industrial pumps and compressors
- Automotive and transmission systems
- Crane hooks and lifting equipment
- Low-speed industrial rotating machinery requiring axial load support
