Deep Groove Ball Bearings FAG 4311 -B-TVH

The FAG 4311 -B-TVH double-row deep groove ball bearing, with a bore of 55 mm and an outside diameter of 120 mm, can withstand high radial loads.

The 4311 -B-TVH deep groove ball bearing is a double-row rolling bearing made from standard rolling bearing steel (100Cr6) with a width of 43 mm. Thanks to the two rows of balls, the design can withstand higher radial forces than single-row versions with the same main dimensions. It is manufactured to tolerance class P0/PN (ABEC 1) with standard radial clearance. The bearing is manufactured by FAG and features a cylindrical outer ring without a flange or groove, making it suitable for compact shaft mountings in mechanical engineering.

What is the 4311 -B-TVH double-row deep groove ball bearing suitable for?

This bearing is suitable for applications in mechanical and plant engineering where high radial forces and axial forces on both sides must be accommodated within a limited axial installation space. As this is an open bearing without integrated seals, it is primarily used in enclosed, oil- or grease-lubricated housings. An external housing seal protects the raceways from contamination and retains the lubricant within the system. The polyamide cage helps to ensure quiet operation.

What distinguishes the variant with a polyamide cage and open design?

The suffix ‘TVH’ denotes the integrated polyamide cage, which, thanks to its low weight, helps to guide the rolling elements. The component is designed for operation within a temperature range of –30 to +120 degrees Celsius. As the open design has no integrated seals, you should select the lubricant and external sealing to suit the relevant environmental conditions. During assembly, check that the 55 mm bore and the 120 mm outer diameter fit precisely.
