39580 Single Cones (Imperial)

39580 Single Cones (Imperial)

The 39580 is a single-row tapered roller bearing cone with a 2.25″ bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 37,500 lbf and operates smoothly in temperatures from -30°C to 110°C.

Its open design allows for easy maintenance, while the steel cage ensures reliable performance. The cone width is 1.1875″, with precise tolerances for a secure fit.

This model is interchangeable with Timken bearings, making it a practical choice for replacements. Ideal for heavy-duty applications like truck axles or industrial machinery where combined loads are common.

Compliant with RoHS and REACH standards, it offers a balance of strength and durability. The standard radial clearance can also be adjusted to C3, C4, or C5 for specific needs.
