Drive Shaft Support Bearing 88508
Drive Shaft Support Bearing 88508
1. Abstracts:
Deep groove ball bearings are the most representative and widely used bearing. It can accommodate axial loads in both directions, in addition to radial loads, even at high speeds. They are available for low noise and low vibration. Bearings with mental shields and rubber seals are pre-lubricated by some grease. Bearing with snap ring and flange on the outer ring. Deep groove ball bearings with filling slots have the same dimensions with standard ones. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots.
2. Specifications of Drive Shaft Support Bearing 88508
- The bore and outside diameter are nominal metric dimensions.
- Also available with a snap ring groove on the OD, with/without the ring.

3. Features of Drive Shaft Support Bearing 88508
(1)The single row deep groove ball bearing are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance.
(2) Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds.
(3) Deep-groove bearings have higher load ratings for their size than shallow-groove, but are also less tolerant of misalignment of the inner and outer races.
(4) A misaligned shallow-groove bearing may support a larger load than the same sized deep-groove bearing with similar misalignment.
(5) This kind of bearing is also availed both in open design and sealed design.
(6) The seals way of the bearing:
RS: contact seal on one side of the bearing
2RS: contact seals on both sides of the bearing
Z: shield on one side of the bearing
ZZ (2Z): shields on both sides of the bearing.
(7) Bearing with RS seals has better sealing but lower limited speed compared with the bearing with Z seals.
