Single row angular contact ball bearings with 40° contact angle and non-contact seals on both sides

These single-row angular contact ball bearings with non-contact seals on both sides and a contact angle of 40° can withstand simultaneous radial and axial loads, whereas axial loads can only be applied in one direction. They feature spherical ball glass fibre reinforced PA66 cages. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.

  • 40° contact angle
  • Integral seals extend bearing life
  • Glass fibre reinforced PA66 cage
  • can withstand high radial loads and high unilateral axial loads
