Axial Deep Groove Ball B. SKF 51106

The SKF 51106 single-direction axial deep groove ball bearing accommodates axial forces in one direction whilst maintaining compact dimensions of 30 × 47 × 11 mm.

The 51106 axial deep-groove ball bearing guides shafts in the axial direction and supports axial forces. Manufactured from standard rolling-element bearing steel (100Cr6), this bearing consists of a shaft ring, a housing ring and the ball set housed between them. SKF manufactures this version to standard tolerances (tolerance class P0/PN or ABEC 1). In mechanical engineering, the separable design allows for the individual components to be fitted separately and in an organised manner onto the shaft and housing.

What loads can the 51106 axial deep-groove ball bearing accommodate?

This design is suitable for applications where purely axial forces act in a defined direction. In bearing arrangements, the rolling bearing absorbs the axial thrust load via the grooves in both rings. The axial bearing must not bear any radial forces; for combined loads, it is therefore necessary to supplement it with separate radial bearings. In addition, a minimum axial load must be maintained to ensure that the rolling elements roll in the raceways without slippage.

What is important to consider with the non-angle-adjustable design?

The bearing has flat contact surfaces and is not angle-adjustable. The connecting parts on the shaft and housing must therefore be machined at right angles to the axis of rotation. Otherwise, misalignment or skewing will lead to localised edge loads on the raceways. The integrated sheet steel cage guides the rolling elements and, together with the roller bearing steel, is suitable for a temperature range of -30 °C to +150 °C.
