Angular Contact Ball B. FAG 7218 -B-MP

The FAG 7218 -B-MP angular contact ball bearing, with main dimensions of 90 × 160 × 30 mm and a 40-degree contact angle, supports high radial and unilateral axial loads.

The FAG 7218 -B-MP angular contact ball bearing is a single-row rolling bearing designed for combined forces. The unit, made from standard rolling-element bearing steel (100Cr6), has a bore of 90 mm, an outside diameter of 160 mm and a width of 30 mm. It is manufactured to tolerance class P0/PN or ABEC 1 with standard radial clearance. Industrial applications involving rotating shafts utilise this design for precise shaft guidance.

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

This single-row bearing supports radial loads as well as axial loads in one direction. Shaft mountings subject to combined loads constitute its primary field of application. The asymmetrical shoulders on the bearing rings transfer the forces obliquely to the radial plane via the raceways.

For axial guidance on both sides, the bearing is usually mounted in the system in a mirror-image configuration opposite a second bearing. In this way, the required operating clearance or a defined bearing preload can be specifically set.

What is the function of the brass cage and the 40-degree contact angle?

The designation ‘B’ indicates a contact angle of 40 degrees. This geometry enables increased axial load-carrying capacity compared with variants with smaller contact angles. The brass cage (suffix MP) guides the rolling elements precisely and retains its dimensional stability even under severe vibrations.

As an open roller bearing without sealing elements, the product is designed for use in enclosed, externally sealed housings. The operating range covers temperatures from -20 to +150 degrees.
