45291 Single Cones (Imperial)

45291 Single Cones (Imperial)

The 45291 is a single-row tapered roller bearing cone with a 2.25-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 34,500 lbf and fits Timken interchangeable models.

Its open design allows easy maintenance, while the steel cage ensures reliable performance. The cone width is 1.2188 inches, with a standard radial clearance option (C3/C4/C5 available).

This cone works well in temperatures from -30°C to 110°C and is ABEC-1 rated for general precision. Ideal for heavy-duty applications like truck axles or industrial gearboxes where combined loads are common.

Compliant with RoHS and REACH standards, it’s a practical choice for replacements or new installations. The effective center location of -0.32 inches helps with precise alignment in assemblies.
