Axial Deep Groove Ball B. SKF 51101

The SKF 51101 single-direction axial deep groove ball bearing transmits axial forces in one direction and, measuring 12x26x9 mm, requires little installation space.

The 51101 axial deep-groove ball bearing is designed to support purely axial loads parallel to the shaft axis. SKF manufactures this component from standard rolling-element bearing steel (100Cr6), which ensures the components have high dimensional stability. With compact dimensions of a 12 mm bore, 26 mm outer diameter and 9 mm height, the bearing supports shafts axially on one side. Due to its design, this construction must not bear radial forces, which is why designers always provide separate radial guidance.

What are the operating conditions for the 51101 axial deep-groove ball bearing?

This thrust bearing is used in bearing arrangements where unidirectional thrust forces parallel to the axis of rotation must be absorbed. A guided sheet steel cage maintains the spacing between the rolling elements and allows for an operating temperature range of -30 to +150 degrees Celsius. The design complies with the standard tolerance class P0/PN or ABEC 1 for common industrial requirements regarding dimensional and concentricity accuracy.

What should be borne in mind when aligning the 51101 series?

This model is not angle-adjustable and is sensitive to misalignment between the shaft and the housing. As the design does not include a shim, the mating parts must be manufactured to be exactly flat and at right angles to the axis of rotation. Otherwise, misalignment will result in uneven load distribution across the raceways. During installation, care must be taken to ensure the correct pairing of the shaft washer and housing washer, as their inner diameters differ slightly to ensure precise guidance.
