The FAG 7211 -B-XL-TVP-P5-UO angular contact ball bearing, measuring 55x100x21 mm, offers precise guidance and a play-free fit for demanding shaft mountings.
The 7211 -B-XL-TVP-P5-UO angular contact ball bearing is a single-row rolling bearing from FAG designed for combined loads. With dimensions of 55 mm bore, 100 mm outer diameter and 21 mm width, it accommodates radial and unilateral axial forces. Thanks to the contact angle of 40 degrees, the design, made from standard roller bearing steel (100Cr6), is specifically suited to higher axial forces. The open component features a polyamide cage and operates within a temperature range of -20 to +120 degrees.
Typical applications include bearing arrangements subject to combined radial and axial loads, where precise shaft guidance and high running accuracy are required. As a single-row angular contact ball bearing can only accommodate axial loads in one direction, it is usually fitted in conjunction with a mating bearing. The contact angle of 40 degrees helps to accommodate stable axial forces along the line of action. The open design allows lubrication via the machine’s existing oil or grease circuit.
The bearing complies with the enhanced tolerance class P5 (corresponding to ABEC 5) and therefore has tighter form and running tolerances than standard bearings. This precision ensures low-vibration operation at demanding speeds. The suffix UO denotes a universal design for installation in pairs: If you combine two bearings in an O or X arrangement, this creates a play-free bearing set without the need for additional shims. When designing the assembly, ensure the environment is clean, as the open bearing has no integrated protection against foreign particles.
Key features include the enhanced running accuracy to tolerance class P5 and the contact angle of 40 degrees. The UO designation allows for installation in pairs in an O or X configuration, in which the bearing assembly remains free of play without the need for additional adjustment.
The main dimensions are 55 mm internal diameter (bore), 100 mm external diameter and 21 mm width. The outer ring is cylindrical in design and has neither a flange nor a ring groove, which allows for direct installation in cylindrical housing bores.
The polyamide cage (designation TVP) guides the rolling elements whilst having a low mass of its own, and ensures smooth, quiet running. The permissible temperature range is between -20 and +120 degrees. If operating temperatures are consistently higher, alternative cage materials should be considered.
As the bearing is designed as an open type without sealing washers, the lubricant reaches the raceways and balls directly. Lubrication is provided by the machine’s lubrication system using a suitable rolling-element bearing grease or gear oil. External housing seals must prevent the ingress of dirt particles and moisture.
The contact angle describes the inclination of the line connecting the points of contact between the ball and the raceways relative to the radial plane. An angle of 40 degrees gives the bearing an increased axial load capacity compared with variants with a smaller nominal contact angle.
Bearings in tolerance class P5 offer tighter concentricity tolerances and more precise mating dimensions than standard bearings. They are used where guidance accuracy, minimal concentricity errors and smooth running are crucial to the function of the shaft.
