Bearings for crane heels are often hub bearing supports. The wheel rotates with the outer rings of the bearing about a stationary shaft. In order to achieve a very high load carrying capacity, the bearing comprises a combination of two radial cylindrical roller bearings with a full complement of rollers and two axial cylindrical roller bearings.

The distance between the bearings should not be too small so that the bearing reaction forces from the axial forces between the wheel and the rail are kept within reasonable limits.
