Four Point Contact B. FAG QJ212 -MPA

The FAG QJ212-MPA four-point bearing (60x110x22 mm) accommodates high axial forces in both directions whilst requiring minimal axial installation space.

The FAG QJ212-MPA four-point bearing is a specialised radial ball bearing designed to accommodate high axial loads from both directions. With dimensions of 60 mm bore, 110 mm outer diameter and 22 mm width, this rolling bearing requires less axial installation space than two separate angular contact ball bearings. Designed as an open bearing with a brass cage and a split inner ring, this unit is suitable for industrial applications in a temperature range from –30 to +150 degrees.

What is the QJ212-MPA four-point bearing suitable for?

The QJ212-MPA four-point bearing is primarily used where varying axial loads occur and defined axial guidance is required. Typical applications include bearing arrangements in which radial forces are absorbed separately. Thanks to the split inner ring, the bearing guides shafts in the axial direction, whilst the outer ring is manufactured without a groove. This design is not intended for purely radial loads.

What are the distinctive features of the QJ212 -MPA four-point bearing with a split inner ring?

The two-piece inner ring allows for the accommodation of a large number of rolling elements, which enhances the axial load-carrying capacity. This non-self-retaining design also simplifies assembly, as the outer ring and the two halves of the inner ring can be fitted separately. The brass cage guides the balls within a temperature range of -30 to +150 degrees. As this is an open bearing without an integrated seal, the bearing location in the housing is sealed externally and supplied with lubricant.
