Angular Contact Ball B. FAG 7310 -B-XL-TVP

The 7310 -B-XL-TVP angular contact ball bearing from FAG Wälzlager, with a 50 mm bore and an 110 mm outer diameter, offers a high axial load-carrying capacity in one direction.

The 7310 -B-XL-TVP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6). Thanks to its pronounced contact angle of 40 degrees, this design accommodates axial forces in one direction in addition to radial forces. The open bearing has standard radial clearance and a tolerance class of P0/PN (ABEC 1). A polyamide cage guides the rolling elements within an operating temperature range of –20 to +120 degrees Celsius.

What is the 7310 -B-XL-TVP angular contact ball bearing suitable for under combined loads?

Design engineers and maintenance personnel primarily use this bearing arrangement for combined loads where the axial force component predominates in one direction. As single-row designs, by their very nature, can only accommodate axial thrust on one side, they are frequently mounted in pairs, facing each other, in mechanical engineering applications. This arrangement allows axial counterforces to be absorbed in a controlled manner and the axial bearing clearance to be adjusted.

What functions do the contact angle and polyamide cage fulfil in this design?

The nominal contact angle of 40 degrees gives the bearing a high axial load-carrying capacity compared to bearings with smaller contact angles. The suffix ‘TVP’ denotes the polyamide cage, which keeps friction low during operation and is suitable for standard lubricants. As the bearing has no integrated seals, a clean installation environment with external housing sealing is required. Before installation, the mounting dimensions of 50x110x27 mm and the specified mounting orientation must be checked.
