Inch tapered roller bearings refer to tapered roller bearings whose dimensions are measured in inches, originating from British and American countries.

Inch tapered roller bearings, the same metric tapered roller bearings, consist of an inner ring, an outer ring and tapered rolling elements. Due to their designed geometry, tapered roller bearings can withstand combined loads (axial and radial). In addition, this design allows the rollers to continue to roll even if the rollers slip on the outer and inner race tracks.

The contact angle of the tapered roller bearing on the raceway is variable, which allows the applied axial and radial load ratio to be offset in any case; in the case of larger angles, there is a greater axial load bearing ability. The bearing is constructed to accommodate combined loads and achieve low friction in operation. Stiff bearing applications can be obtained by inter-aligning and preloading one single row tapered roller bearing with another tapered roller bearing.

Features Inch tapered roller bearings

-- Single layer inner and outer ring.

-- One-piece stamped steel cage holds the rollers on the inner ring and isolates them evenly.

-- Additional pin cages are available.

The prefix letter consists of 1-2 letters and is used to indicate the service level of the designed bearing.
