Single Direction Thrust Ball Bearings

High-Precision Thrust Ball Bearings for Unidirectional Axial Load Applications

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
