Versatile Qj306n2ma/c2l Skf Four Point Contact Ball Bearing 30x72x19mm Massive 45% Savings [jvgT62Ky]

SKF 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.

Both inner ring halves of SKF Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an SKF cylindrical roller bearing (fig. 1). In addition, these recesses can be used to facilitate dismounting.

Four-point contact ball bearings can accommodate high axial loads in both directions and small radial loads. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves.
High-speed capability
Accommodate high axial loads in both directions and small radial loads
Require considerably less axial space than double row angular contact ball bearings
The locating slots can be used to prevent the outer ring from rotating
