863X Single Cones (Imperial)

863X Single Cones (Imperial)

The 863X single cones are imperial-sized tapered roller bearings with a 3.937-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 103,000 lbf and static loads up to 142,000 lbf.

Their open design and steel cage ensure reliable performance, with a temperature range of -30°C to 110°C. The cones are interchangeable with Timken models, making them a practical choice for replacements.

These bearings are ideal for heavy-duty applications like industrial machinery or vehicle axles, where robust performance is needed. They come in standard radial clearance but are also available in C3, C4, or C5 options for specific needs.

Compliant with RoHS and REACH standards, the 863X series offers a balance of strength and versatility for demanding environments. Their ABEC-1 rating ensures consistent quality for general industrial use.
