Cup (Single Row)

Tapered roller bearing cups are the outer race components of tapered roller bearing assemblies, designed to work in conjunction with matching cones and rollers. These precision-ground steel cups feature a tapered raceway that accommodates combined radial and axial loads, making them ideal for applications where forces act in multiple directions. The cup is typically press-fitted into the housing bore and remains stationary during operation.

When selecting a single row tapered roller bearing cup, match the part number precisely to the corresponding cone assembly to ensure proper geometry and load ratings. Cup dimensions are defined by outer diameter (OD) and width, with designations following industry-standard numbering systems. Common applications include automotive wheel hubs, industrial gearboxes, conveyor systems, and agricultural equipment where replaceable outer races simplify maintenance and extend service life.
