Deep groove ball bearing with filling slots
Single row deep groove ball bearings with filling slots accommodate more balls than standard deep groove ball bearings. They are of a simple, yet versatile, design and are robust in operation, requiring little maintenance. They can accommodate radial and axial loads in both directions. They have a higher radial load carrying capacity than the corresponding bearings without filling slots but have a limited axial load carrying capacity due to the filling slots.

  • Simple, versatile and robust design
  • Accommodate higher radial loads than corresponding bearings without filling slots, with limited axial loads in both directions
  • Require little maintenance
