Product introduction
Tapered roller bearings are mainly used to bear radial and axial combined loads based on radial loads, generally not suitable to bear axial loads alone, such bearings can be installed respectively the inner ring (with a full set of rollers and retainers) and the outer ring. This type of bearing does not allow the shaft to tilt relative to the housing, resulting in additional axial forces under radial load.
