Angular Contact Ball B. FAG 7312 -B-XL-TVP-UA

The single-row FAG angular contact ball bearing 7312 -B-XL-TVP-UA, measuring 60x130x31 mm, is designed for combined radial and axial loads.

The FAG 7312 -B-XL-TVP-UA angular contact ball bearing is a single-row rolling bearing specifically designed for combined loads. Thanks to its 40-degree contact angle, this design withstands high axial forces in one direction. Manufactured from standard rolling-element bearing steel (100Cr6), this version features a lightweight polyamide cage and standard radial clearance. As an open component without integrated seals, the bearing allows for direct lubricant supply via the surrounding housing.

In which applications is the 7312 -B-XL-TVP-UA angular contact ball bearing used?

This rolling bearing is used in bearing arrangements where axial forces acting in one direction and radial loads act simultaneously on the shaft. As single-row angular contact ball bearings can only accommodate axial forces in one direction, the component is usually paired with a second bearing. The cylindrical outer ring, which has no groove and no flange, allows for installation in smooth housing bores. At the same time, the polyamide cage contributes to low-vibration operation of the rolling elements.

What distinguishes the UA design for paired mounting?

The suffix ‘UA’ denotes a universal bearing for installation in pairs. When two of these angular contact ball bearings are mounted in an O or X arrangement, the bearing pair is supplied by the manufacturer with a small amount of axial clearance. This eliminates the need for shims or manual adjustment of the bearing clearance during assembly. When operating the bearing assembly, the specified temperature range of -20 to +120 degrees must be observed to avoid thermal overload of the material and the polyamide cage.
