618/670 TN

Deep groove ball bearing
Single row deep groove ball bearings are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types.

  • Simple, versatile and robust design
  • Low friction
  • High-speed capability
  • Accommodate radial and axial loads in both directions
  • Require little maintenance
