Axial Deep Groove Ball B. FAG 51113

FAG Wälzlager single-direction axial deep-groove ball bearing 51113, dimensions 65x90x18 mm, designed to accommodate high axial forces in one direction.

The 51113 axial deep-groove ball bearing from FAG Wälzlager supports shafts against unidirectional axial forces. Manufactured from standard bearing steel (100Cr6), the component is characterised by dimensionally stable raceways. A sturdy sheet steel cage maintains an even spacing between the rolling elements. This open-type component is suitable for a temperature range of –30 to +150 degrees and can be flexibly integrated into oil- or grease-lubricated assemblies in mechanical engineering.

What is the 51113 axial deep-groove ball bearing suitable for?

This bearing accommodates purely axial loads from a defined direction. Due to its design, this type of bearing cannot transmit radial forces; therefore, radial shaft support must be provided by separate radial bearings on the same shaft. As this version of the 511 series is not angularly adjustable, the bearing mounting requires precisely machined, right-angled contact surfaces on the housing and shaft.

What installation requirements does the 51113 axial deep groove ball bearing have?

During assembly, it is essential to ensure the correct allocation of the shaft and housing washers. The shaft washer has the smaller internal diameter and fits tightly on the shaft, whilst the housing washer, with its larger bore, has some clearance relative to the shaft. The bearing is supplied with standard tolerances (tolerance class P0/PN or ABEC 1) and without a shim. Misalignment between the housing and shaft axes must be avoided during design, as angular errors lead to uneven force distribution on the ball set.
