SKF 25821/2/Q Single row tapered roller bearing, cup, inch size

Tapered roller bearing cups (outer ring), inch sizes, are intended to be combined with cones (inner ring with rollers and cage) from the same series. Together they create a complete bearing that accommodates combined radial and axial loads and provides low friction during operation. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.
