864 Single Cones (Imperial)

864 Single Cones (Imperial)

The 864 single cones are imperial-sized tapered roller bearings with a 3.75″ 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 single-row construction and open design make them easy to maintain, while the steel cage ensures reliable performance. The bearings operate smoothly in temperatures ranging from -30°C to 110°C.

These cones are interchangeable with Timken bearings, offering a practical replacement option. Ideal for heavy-duty applications like truck axles or industrial machinery where robust performance is needed.

Compliant with RoHS and REACH standards, they provide a safe and dependable solution for demanding environments.
