Axial Deep Groove Ball B. FAG 51311

The FAG 51311 single-direction axial deep-groove ball bearing accommodates purely axial forces and has main dimensions of 55 x 105 x 35 mm.

The 51311 axial deep-groove ball bearing is designed to accommodate single-direction axial forces. With a bore of 55 mm, an outside diameter of 105 mm and a height of 35 mm, the shaft collar provides axial guidance on the rotating shaft. Manufactured from standard rolling bearing steel (100Cr6), the bearing operates within a temperature range of -30 to +150 degrees Celsius. The guided sheet steel cage maintains a uniform spacing between the rolling elements.

In which applications is the 51311 axial deep-groove ball bearing used?

This rolling bearing is designed to accommodate axial loads acting on the shaft from a single direction only. As this design is not intended to accommodate radial forces, it is usually combined in practice with separate radial bearings. Typical applications include vertical shaft mountings and assemblies in which defined axial thrust forces occur. The flat housing washer requires a perpendicular contact surface, as this design is not angle-adjustable.

What are the characteristics of the version without a shim?

The 51311 axial deep-groove ball bearing is designed to standard tolerance (P0/PN or ABEC 1) as a bearing set without an additional shim. The shaft washer, housing washer and the ball-guided sheet steel cage can be fitted separately, which facilitates installation in assemblies. As the bearing does not automatically compensate for manufacturing-related misalignment, precise alignment of the connecting parts is essential to prevent localised edge pressure on the rolling elements.
