Angular Contact Ball B. FAG 7311 -B-XL-TVP

The FAG 7311 -B-XL-TVP angular contact ball bearing (55x120x29 mm) accommodates high radial loads as well as single-direction axial loads at a 40-degree contact angle.

The 7311 -B-XL-TVP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6). The design, with a 55 mm bore, 120 mm outer diameter and 29 mm width, features angularly offset raceways. This enables the open bearing to effectively dissipate combined loads. The component is particularly suitable for bearing arrangements where rotating shafts must be guided precisely and axial forces must be supported in one direction.

What is the 7311 -B-XL-TVP angular contact ball bearing with a 40-degree contact angle suitable for?

The 7311 -B-XL-TVP angular contact ball bearing is suitable for bearing arrangements where radial loads and high axial forces in one direction occur simultaneously. Thanks to its large contact angle of 40 degrees, the component effectively absorbs axial loads. It is frequently used in combined bearing arrangements where the axial load is predominantly on one side.

As single-row angular contact ball bearings can only accommodate axial forces in one direction, they are usually mounted in conjunction with a second bearing. This mating bearing supports the axial force in the opposite direction and ensures that the rotating shaft is guided without play or with a specific preload.

What are the distinctive features of the -B-XL-TVP design?

The -B-XL-TVP design is characterised by a contact angle of 40 degrees and a lightweight polyamide cage. The polyamide cage promotes smooth running and reduces friction losses during acceleration in the temperature range from –20 to +120 degrees Celsius.

As an open rolling bearing, this variant has no factory-fitted seals. The bearing can be integrated directly into an external lubrication circuit using oil or grease. A clean installation environment and suitable sealing elements in the housing help to keep dirt particles away from the rolling elements.
