Angular Contact Ball B. FAG 7218 -B-XL-TVP

The FAG 7218 -B-XL-TVP angular contact ball bearing, with a 90 mm bore and a 40-degree contact angle, can accommodate high unilateral axial and radial forces.

The 7218 -B-XL-TVP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) for demanding industrial applications. With a bore of 90 mm, an outer diameter of 160 mm and a width of 30 mm, this design is suitable for shaft mountings subject to combined loads. As an open bearing, the component can be integrated directly into an existing lubrication system. The integrated polyamide cage guides the rolling elements stably at operating temperatures ranging from -20 to +120 degrees Celsius.

What is the 7218 -B-XL-TVP angular contact ball bearing suitable for in industrial applications?

Single-row angular contact ball bearings of this design are primarily used where radial forces occur in conjunction with axial forces acting from one side. The contact angle of 40 degrees gives the bearing a high axial load capacity in one direction. Typical applications include shaft mountings in general mechanical engineering with combined load directions. As the bearing can only be loaded axially in one direction, users often fit a second counter-bearing in a mirror-symmetrical arrangement to accommodate axial forces acting from both sides.

What are the advantages of the 40-degree contact angle and the TVP cage?

The suffix ‘TVP’ denotes a polyamide cage, which reduces friction on the raceways due to its low weight. Together with the 40-degree contact angle, the component can accommodate higher axial loads than variants with a smaller angle. The bearing has a standard radial clearance and the standard tolerance class P0 (ABEC 1). Designers and maintenance engineers must take into account during the planning stage that the open design requires external sealing of the bearing housing to protect against contamination and moisture.
