QJ311MA SKF Four Point Contact Ball Bearing 55x120x29mm Open Weight (g) 245SKF 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 (Load ratio). The bearings are separable, i. e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
