D/W R2 R-2Z

Stainless steel deep groove ball bearing with flanged outer ring and integral sealing
Stainless steel single row deep groove ball bearings with flanged outer ring and seals or shields on both sides 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 other bearing types. The flanged outer ring facilitates axial location of the bearings within their housings. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

  • Greater chemical and corrosion resistance
  • Flanged outer ring facilitates axial location of the bearings within their housings
  • Integral sealing prolongs bearing service life
