Axial Deep Groove Ball B. SKF 53309

The SKF 53309 axial deep groove ball bearing accommodates single-sided axial forces with a 45 mm bore, an 85 mm outer diameter and a 30.1 mm overall height.

The 53309 axial deep-groove ball bearing accommodates pure axial forces in one direction and provides single-sided axial support for the mounted shaft. SKF manufactures the components from standard rolling-bearing steel (100Cr6). A dimensionally stable sheet steel cage guides the rolling elements evenly along their paths. The bearing is designed for operating temperatures ranging from –30 to +150 °C and meets the standard tolerance class P0/PN (ABEC 1). As it cannot accommodate radial forces, it is combined in the design with separate radial bearings.

What role does the 53309 axial deep-groove ball bearing play in applications with unilateral axial loads?

This axial bearing is used in bearing arrangements where pure axial forces must be supported in one direction. The separable design facilitates assembly: the shaft ring, housing ring and ball-cage assembly can be assembled separately and then positioned and fitted onto the shaft one after the other. Additional radial bearings ensure that no transverse forces act on the axial bearing.

When is angular adjustability crucial for bearing 53309?

The 53309 axial deep-groove ball bearing features a spherical housing washer that can compensate for misalignment between the shaft and the housing. This compensating movement works in conjunction with a suitable spherical shim. In the case of slight misalignments or deflections, the housing disc settles into the recess of the washer, helping to prevent edge stresses. The scope of supply includes the axial deep-groove ball bearing without a washer, meaning that the contact surface of the connecting structure must be specified separately.
