Axial Deep Groove Ball B. SKF 51120

The SKF 51120 axial deep-groove ball bearing accommodates unilateral axial forces on shaft diameters of 100 mm and has an outside diameter of 135 mm and a width of 25 mm.

The SKF 51120 axial deep groove ball bearing is a separable rolling bearing designed to support purely axial loads from one direction. Manufactured from standard rolling-element bearing steel (100Cr6), the component provides axial support for vertically or horizontally mounted shafts. The assembly consists of a shaft ring, a housing ring and a guided set of rolling elements in a sheet steel cage. At operating temperatures ranging from –30 to +150 degrees, the thrust bearing maintains its dimensional stability in demanding industrial environments.

What loads is the 51120 axial deep-groove ball bearing designed for?

Designs in mechanical and plant engineering utilise this axial bearing when high axial forces act on the shaft in one direction. As the bearing is not designed for radial loads, it is installed in combination with separate radial bearings. The open design allows direct access of lubricant – oil or grease – from within the surrounding unit.

Why is angular adjustability crucial for the 51120 axial deep groove ball bearing?

The 51120 axial deep-groove ball bearing is not angularly adjustable and is supplied without a shim. Right-angled and flat mating surfaces on the shaft and housing are therefore essential to prevent edge stresses on the rolling elements. In the event of misalignment or shaft deflection, the design does not compensate for any angular misalignment. Compliance with tolerance class P0/PN or ABEC 1, when correctly installed, ensures smooth running across the entire circumference of the balls.
