Axial Deep Groove Ball B. SKF 51314

The SKF 51314 axial deep-groove ball bearing accommodates unidirectional axial forces and is designed for shafts with dimensions of 70x125x40 mm in mechanical engineering.

The SKF 51314 axial deep groove ball bearing is a separable rolling bearing designed to accommodate pure axial loads in one direction. With key dimensions of a 70 mm bore, 125 mm outside diameter and 40 mm height, this bearing supports shafts and machine components axially. The design consists of standard rolling-bearing steel (100Cr6) with a guided sheet steel cage. It is suitable for operating temperatures ranging from –30 to +150 degrees and complies with tolerance class P0/PN or ABEC 1.

What is the 51314 single-direction axial deep groove ball bearing suitable for?

This rolling bearing is used in designs where axial forces are supported in one direction and no radial forces act on the bearing mounting. Typical applications include vertical shaft mountings and assemblies in general mechanical engineering. As the bearing is not angularly adjustable, operation requires right-angled machined mounting shoulders on the shaft and housing to prevent edge loading.

What should be taken into account when mounting the 51314 axial deep groove ball bearing without a washer?

This version comprises the axial deep-groove ball bearing alone, without a washer. As this design does not compensate for misalignment due to its construction, it requires rigid and plane-parallel contact surfaces. The allocation of the washers depends on the diameters: the shaft washer with a 70 mm bore is fitted onto the shaft with a press fit, whilst the housing washer with an outer diameter of 125 mm is guided within the housing. The sheet steel cage keeps the balls in their raceway.
