The rolling elements of Tapered Roller Bearings look like truncated cones.

The inner ring (cone) has a special back face rib at the large cone diameter for axial load purposes. The front face rib at the smaller cone diameter together with the cage avoids dropping out of rollers.

For easy mounting the outer ring (cup) has no shoulders.

IBC Tapered Roller Bearings are designed for high radial and unidirectional axial loads for medium rotational speed. Generally the series 30..A, 31..A, 32..A are available. Arrangement in pairs allows for axial load in both directions.

Due to contact angle Tapered Roller Bearings are intended for axial loads. Therefore a second bearing for counter guidance is necessary.
