Angular Contact Ball B. FAG 7217 -B-XL-TVP

The single-row angular contact ball bearing 7217 -B-XL-TVP from FAG Wälzlager, measuring 85 × 150 × 28 mm, accommodates combined radial and single-direction axial loads.

The 7217 -B-XL-TVP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with standard radial clearance and tolerance class P0/PN or ABEC 1. The inner and outer rings have offset raceways, ensuring that force transmission takes place at a defined contact angle. As an open bearing, this design has no integrated seals. Consequently, the lubricant from the surrounding structure reaches the rolling elements directly.

What is the 7217 -B-XL-TVP angular contact ball bearing suitable for?

This bearing is used in shaft mountings where radial forces and significant axial forces in one direction occur simultaneously. Typical applications include designs subject to high combined loads in general mechanical engineering. As a single single-row angular contact ball bearing can only accommodate axial forces in one direction, in practice it is often paired with a second bearing. The cylindrical outer ring without a flange allows for flush mounting in suitable housing bores.

What are the functions of the contact angle and the polyamide cage?

The nominal contact angle of 40 degrees gives the rolling bearing a high axial load-carrying capacity in the direction of action. The integrated polyamide cage (TVP) guides the balls evenly and is characterised by its low weight, which reduces friction during operation. This design is rated for operating temperatures ranging from -20 to +120 degrees. When designing the bearing mounting, it is important to ensure that open designs are protected against the ingress of dirt and are lubricated via the housing.
