Deep Groove Ball Bearing Shielded Type

  • Shielded type (ZZ).

About Deep Groove Ball Bearing

  • Single row deep groove ball bearing (open type, shielded type, sealed type); bore diameter 10 to 240mm.
  • Single row deep groove ball bearing (open type); bore diameter 260 to 800mm.

Maximum Type Ball Bearings

  • Maximum Type Ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings.
  • Because of their filling slots, they are not suitable for applications with high axial loads.
  • BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively.
  • Besides the open type, ZZ type shielded bearings are also available.
  • When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible.
  • Their cages are pressed steel.

Precautions For Use Of Deep Groove Ball Bearings

  • For deep groove ball bearings, if the bearing load is too small during operation, slippage occurs between the balls and raceways, which may result in smearing.
  • The higher the weight of balls and cage, the higher this tendency becomes, especially for large bearings. If very small bearing loads are expected.
