Angular Contact Ball B. FAG 7313 -B-XL-TVP

The 7313 -B-XL-TVP angular contact ball bearing from FAG Wälzlager, measuring 65x140x33 mm, accommodates high axial forces on one side as well as radial forces.

The 7313 -B-XL-TVP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6). Thanks to its contact angle of 40 degrees, this design can handle combined loads where radial and axial forces occur simultaneously. The bearing is manufactured by FAG and features a standard radial clearance as well as tolerance class P0/PN (ABEC 1). Due to their design, single-row versions can only accommodate axial loads in one direction and usually require a mating bearing to counteract them when load directions vary.

What is the 7313 -B-XL-TVP angular contact ball bearing suitable for in industrial applications?

This rolling bearing is used in bearing arrangements that must simultaneously support radial loads and high unilateral axial loads. Typical applications can be found in general mechanical engineering and in gearbox applications with defined load directions. With internal and external diameters of 65 mm and 140 mm respectively, and a width of 33 mm, the design is suitable for rigid shaft mountings. As this is the standard version, the bearing is usually paired with a second angular contact ball bearing.

What advantages do the 40-degree contact angle and the polyamide cage offer?

The designation ‘B’ stands for the 40-degree contact angle, which enables increased axial load-carrying capacity in one load direction. The polyamide cage (suffix ‘TVP’) guides the rolling elements within a temperature range of –20 to +120 degrees Celsius. As an open bearing, the component has no integrated lip seals. Design engineers and maintenance personnel must therefore ensure that the system is fitted with a suitable external housing seal and a properly coordinated lubrication supply using grease or oil.
