Four Point Contact B. FAG QJ215 -MPA

The FAG QJ215-MPA four-point bearing, measuring 75 × 130 × 25 mm, accommodates axial loads in both directions whilst requiring minimal axial installation space.

The FAG QJ215 -MPA four-point bearing is a specialised rolling bearing capable of withstanding high axial forces in both directions. Due to the four contact points between the balls and the raceways, this design often replaces two angular contact ball bearings mounted opposite each other, thereby saving axial installation space. With a bore of 75 mm, an outside diameter of 130 mm and a width of 25 mm, this bearing is suitable for demanding industrial applications.

In which installation scenarios does the QJ215-MPA four-point bearing prove its worth?

Typical applications for the QJ215-MPA four-point bearing are found where predominantly axial loads occur and precise axial guidance of the shaft is required. The bearing is frequently used as an axial guide bearing, often in combination with a separate radial bearing. Thanks to the split inner ring and the open design, the rolling bearing can be handled separately during assembly, which facilitates installation in housings.

What are the distinctive features of the version with a split inner ring and brass cage?

The variant with the suffix -MPA features a robust brass cage that guides the rolling elements and is suitable for operating temperatures ranging from -30 to +150 degrees. The split inner ring allows for a large number of balls to be accommodated, ensuring high load-carrying capacity. As this is an open bearing without an integrated seal, the bearing location must be protected externally against dirt and supplied with a suitable lubricant.
