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

These single row angular contact ball bearings, with 40° contact angle and non-contact seals on both sides, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only.

They have a ball-centred glass-fibre reinforced PA66 cage. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.

  • 40° contact angle
  • Integral sealing prolongs bearing service life
  • Glass-fibre reinforced PA66 cage
  • Accommodate relatively high radial loads and large unilateral axial loads
