HM259048WS Single Cones (Imperial)

The HM259048WS is a single-row tapered roller bearing cone with a 12.5-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 380,000 lbf and static loads up to 628,000 lbf.

Its open design allows easy maintenance, while the steel cage ensures reliable performance. The cone has a width of 3.375 inches and fits well in heavy-duty applications.

This model is interchangeable with Timken bearings, making it a practical choice for replacements. Ideal for industrial machinery, gearboxes, or large equipment where high radial and thrust loads are common.

It operates smoothly in temperatures from -30°C to 110°C and complies with RoHS and REACH standards. The standard radial clearance can be adjusted to C3, C4, or C5 as needed.
