Axial Deep Groove Ball B. FAG 51213

The 51213 axial deep-groove ball bearing from FAG Rolling Bearings, with dimensions of 65 × 100 × 27 mm, accommodates high unilateral axial forces in mechanical engineering.

The 51213 axial deep-groove ball bearing is designed to accommodate purely axial forces in one direction. This rolling bearing consists of a shaft ring with a 65 mm bore, a housing ring with an outer diameter of 100 mm, and a guided ball set with a robust sheet steel cage. Manufactured from standard roller bearing steel 100Cr6, the design is suitable for a temperature range of -30 to +150 °C. With a width of 27 mm, the bearing guides rotating shaft components in the axial direction and supports them against unilateral thrust.

In which applications does the 51213 axial deep groove ball bearing absorb axial forces?

This rolling bearing is used where axial loads acting in a defined direction parallel to the axis of rotation need to be supported. The single-sided design supports shafts in one direction and must not be subjected to radial forces. Typical applications are found in bearing arrangements subject to purely axial loads. As it is manufactured to tolerance class P0/PN (corresponding to ABEC 1), the component fits into standardised fit systems used in general mechanical engineering.

What is important to bear in mind when fitting the non-angle-adjustable design?

Model 51213 is not angle-adjustable and is fitted without a separate shim. Planar, parallel contact surfaces on the shaft and housing are therefore essential, as misalignment leads to localised edge loads on the raceways. Connecting components must be aligned at right angles to the shaft axis. As the shaft washer, housing washer and ball cage are supplied separately, the axial bearing can be fitted in stages; however, a minimum axial load must be maintained at all times during assembly to guide the rolling elements.
