Combined needle roller and angular contact ball bearings for bi-directional axial loads

These bearings consist of radial needle roller bearings and angular contact ball bearings. The combined bearings are able to withstand heavy radial loads and lower axial loads in both directions. In addition, they operate at high speeds. Their small cross-section makes them particularly suitable for equipment applications where other types of locating end bearing configurations take up too much space.

  • Can withstand radial and axial loads
  • Relatively high load carrying capacity
  • High speed capability
  • Small cross-section
  • Separable design
