QJ 336 N2MA SKF Four-point contact ball bearing

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported. The bearings are separable, i. e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. These bearings take up considerably less axial space than double row bearings.
