Stainless steel deep groove ball bearing

Stainless steel single row deep groove ball bearings provide greater chemical and corrosion resistance.

As with deep groove ball bearings generally, they 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.

  • Greater chemical and corrosion resistance
  • Simple, versatile and robust design
  • Low friction and high-speed capability
  • Accommodate radial and axial loads in both directions
  • Require little maintenance
