HM88649H Single Cones (Imperial)

HM88649H Single Cones (Imperial)

The HM88649H is a single-row tapered roller bearing cone with a 1.375″ bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 20500 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″, 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 gearboxes 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 for specific needs.
