47490 Single Cones (Imperial)

47490 Single Cones (Imperial)

The 47490 is a single-row tapered roller bearing with a 2.8125-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 40200 lbf and static loads up to 56000 lbf.

Its open design allows for easy maintenance, while the steel cage ensures reliable performance. The bearing operates smoothly in temperatures ranging from -30°C to 110°C.

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

Compliant with RoHS and REACH standards, it offers a balance of strength and longevity. The standard radial clearance can be adjusted to C3, C4, or C5 as needed.
