Stainless steel deep groove ball bearings

Stainless steel single row deep groove ball bearings have higher chemical and corrosion resistance. Due to their wide use and versatility, deep groove ball bearings have very low friction and are optimised to reduce noise and vibration, thereby increasing rotational speeds. Capable of withstanding radial loads and bi-directional axial loads, they are easy to mount and require much less required maintenance than many other bearing types.

  • Improved resistance to chemicals and corrosion
  • Simple, versatile and robust design
  • Low friction
  • High speed capability
  • Withstands radial loads and axial loads in both directions
  • Virtually maintenance free
