Axial Deep Groove Ball B. SKF 51215

The SKF 51215 axial deep groove ball bearing accurately supports unilateral axial loads with a shaft diameter of 75 mm, an outer diameter of 110 mm and a height of 27 mm.

The SKF 51215 axial deep groove ball bearing is designed to support pure axial loads in one direction. The assembly consists of a shaft disc with a 75 mm bore, a housing disc with an 110 mm outer diameter, and a guided rolling element set. As it is manufactured from through-hardened standard roller bearing steel 100Cr6, the raceways retain their shape even under high loads. This separable bearing unit is used on shaft sections where axial forces are supported separately from radial bearings.

What loads does the 51215 axial deep-groove ball bearing accommodate?

This single-direction axial bearing is designed for applications where high axial thrust forces occur parallel to the shaft axis. As the rolling elements transmit pure shear forces in the longitudinal direction of the shaft, no radial load must act on the bearing rings. To accommodate any transverse forces that may occur, designers combine this unit with a separate radial bearing on the same shaft.

What is important when installing bearing 51215?

Design engineers must ensure that the contact surfaces on the shaft and housing are precisely perpendicular and flat. The 512 series is not angle-adjustable and is sensitive to misalignment or tilting. This version is single-direction and does not include a separate washer. The integrated sheet steel cage guides the rolling elements within a temperature range of -30 to +150 degrees. The bearing complies with standard tolerance P0 (ABEC 1) for standardised industrial applications.
