28579 Single Cones (Imperial)

The 28579 single cone is an imperial-sized tapered roller bearing with a 1.968″ bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 22200 lbf and fits Timken-interchangeable applications.

Its open design and steel cage ensure reliable performance, with a standard radial clearance (C3/C4/C5 options available). The cone width is 1″, making it compact yet robust for its size.

This bearing operates smoothly in temperatures from -30°C to 110°C, suitable for industrial machinery or heavy equipment. Its ABEC-1 rating offers dependable precision for general use.

Compliant with RoHS and REACH standards, it’s a practical choice for replacements or new installations where combined loads are expected. The effective center location of -0.19″ helps with precise alignment.
