Axial Deep Groove Ball B. SKF 53220

The SKF 53220 single-direction axial deep groove ball bearing with a 100 mm bore accommodates axial forces in one direction.

The 53220 axial deep-groove ball bearing is a separable rolling bearing designed for pure axial loads in one direction. Manufactured from standard rolling-element bearing steel (100Cr6), this bearing consists of a shaft ring, a housing ring with a spherical raceway, and a guided set of balls in a sheet steel cage. With a bore diameter of 100 mm, an outside diameter of 150 mm and a height of 40.9 mm, the bearing provides axial support for rotating shafts. It is manufactured to the Normal tolerance class (P0/PN or ABEC 1) for industrial applications.

What loads and mounting conditions apply to the 53220 axial deep-groove ball bearing?

This axial bearing is designed for applications where axial forces must be supported in one direction and no radial forces act on the bearing assembly. Typical applications include vertical shaft arrangements and pure axial guidance. The fact that the shaft and housing washers can be separated facilitates the assembly of the individual components within the housing. As the rolling bearing is designed for a temperature range of –30 to +150 °C, it is suitable for thermally demanding operating environments in mechanical engineering.

When does the 53220 axial deep-groove ball bearing require a washer?

The housing washer in this design has a hollow spherical outer surface. When used in conjunction with a spherical shim, which must be procured separately, the 53220 axial deep groove ball bearing compensates for angular misalignment between the housing and the shaft caused by manufacturing or assembly. The scope of supply includes only the bearing without the shim. If there is no flat, perpendicular contact surface in the housing, the shim helps to prevent impermissible edge pressures. The dimensionally stable sheet steel cage guides the rolling elements evenly during operation.
