Four Point Contact B. FAG QJ207 -MPA

The FAG QJ207-MPA four-point bearing, with a 35 mm bore and a split inner ring, accommodates axial forces in both directions whilst requiring minimal installation space.

The FAG QJ207-MPA four-point bearing is a rolling bearing which, thanks to its raceway geometry, accommodates axial forces in both directions. With key dimensions of a 35 mm bore, 72 mm outer diameter and 17 mm width, this design is suitable for compact constructions. The bearing features a brass cage and standard radial clearance. Thanks to its tolerance class P0/PN (ABEC 1), this open rolling bearing complies with current standards in mechanical engineering.

What is the QJ207-MPA four-point bearing suitable for in mechanical engineering?

The QJ207-MPA four-point bearing accommodates axial loads from varying directions when the installation space for two separate angular contact ball bearings is limited. Typical applications include assemblies subject to combined loads or gear stages. This bearing is often used in combination with a radial bearing as an axial guide bearing. The permissible temperature range extends from –30 to +150 degrees, enabling the component to cope with thermally demanding environments.

What function does the split inner ring fulfil during assembly and operation?

The split inner ring is the key design feature of this four-point bearing. As the bearing is not self-retaining, the inner ring halves and the outer ring with the ball cage can be fitted separately onto the shaft and into the housing. This simplifies installation. The outer ring is manufactured without a retaining groove. As this is an unsealed bearing, an external housing seal helps to protect the raceways.
