Axial Deep Groove Ball B. FAG 51120

The FAG 51120 single-direction axial deep-groove ball bearing accommodates purely axial forces and has main dimensions of 100 × 135 × 25 mm.

The FAG 51120 axial deep-groove ball bearing is designed to accommodate high axial loads from a single direction. With a bore of 100 mm, an outside diameter of 135 mm and a height of 25 mm, this rolling bearing provides axial support for rotating shafts. Manufactured from standard roller bearing steel 100Cr6 and fitted with a dimensionally stable sheet steel cage, this design is used in industrial mechanical engineering.

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

This single-acting axial bearing is particularly suitable for bearing arrangements in which only axial forces act in one direction. Due to its design, this type of bearing must not accommodate radial loads; users must therefore transfer radial forces via separate radial bearings. Typical applications can be found wherever housing surfaces provide axial support for rotating shafts and no tilting moments or radial forces act on the discs.

What is important when fitting the bearing without a washer?

As the bearing is not angle-adjustable and is supplied without a spherical washer, the housing and shaft connections must be machined at right angles to the axis of rotation. The design does not compensate for misalignment or skew. Contact surfaces require precise alignment of both the shaft and housing flanges to prevent edge running. The permissible temperature range is from –30 to +150 degrees Celsius.
