Axial Deep Groove Ball B. SKF 52208

The SKF 52208 double-acting axial deep groove ball bearing accommodates axial loads in both directions and measures 30x68x36 mm.

The 52208 axial deep-groove ball bearing is a separable rolling bearing designed for industrial applications. This axial bearing supports purely axial forces and guides shafts in both directions. This design is not intended for radial loads. SKF manufactures the components from standard rolling-bearing steel (100Cr6). Manufacture to tolerance class P0/PN (corresponding to ABEC 1) ensures the dimensional and running accuracy required in mechanical engineering.

What loads and mounting conditions does the 52208 axial deep-groove ball bearing handle?

The bearing is used in designs where axial forces act alternately on the shaft from both directions. The integrated sheet steel cage guides the rolling elements in an orderly manner and is suitable for operating temperatures ranging from –30 to +150 degrees Celsius. As the design accommodates axial loads only, the bearing is usually combined with separate radial bearings within the overall system to absorb transverse forces.

What should be borne in mind with the double-acting design without washers?

This double-acting design consists of a shaft disc with a 30 mm bore diameter, two housing discs with an outer diameter of 68 mm, and two ball rings. The resulting overall height or width is 36 mm. This model is not angle-adjustable and is designed without shims. The mating surfaces on the shaft and housing must therefore be precisely aligned at right angles to the axis of rotation. Misalignment or tilting leads to edge stresses, uneven load distribution and increased wear.
