Axial Deep Groove Ball B. SKF 52220

The SKF 52220 axial deep groove ball bearing accommodates axial forces in both directions and has dimensions of 85 × 150 × 67 mm; it is used in general mechanical engineering.

The SKF 52220 axial deep groove ball bearing is designed as a double-acting rolling bearing. It guides shafts axially in both directions and accommodates thrust forces from alternating directions. Manufactured from standard rolling-bearing steel (100Cr6), the bearing has a bore of 85 mm, an outside diameter of 150 mm and a total width of 67 mm. A guided sheet steel cage maintains an even spacing between the rolling elements. This design is intended for use without separate shims.

What is the 52220 axial deep-groove ball bearing suitable for?

As a double-acting design, this type is primarily used in bearing arrangements subject to purely axial loads acting alternately from two directions. The bearing must not accommodate radial forces. Typical applications include bearing arrangements where defined axial guidance on both sides is required. As this component is not angularly adjustable, the bearing arrangement requires right-angled mounting shoulders on the shaft and housing to prevent harmful edge pressures from developing on the raceways.

What characterises the P0/PN design and tolerance class?

This rolling bearing complies with the standard tolerance class P0/PN (comparable to ABEC 1) for standardised dimensional and running accuracy in industrial applications. The permissible temperature range extends from –30 to +150 degrees Celsius, depending on the lubricant used. The design requires careful assembly: the central shaft disc sits firmly on the shaft, whilst the two outer housing discs are positioned axially within the housing to absorb alternating thrust forces.
