/857-Single-Cones-(Imperial)-Dimensions.webp)
The 857 single cones are imperial-sized tapered roller bearings with a 3.625″ 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 allow for easy maintenance and efficient heat dissipation. The steel cage ensures reliable performance, even in demanding conditions with temperatures ranging from -30°C to 110°C.
These cones are interchangeable with Timken bearings, making them a practical choice for replacements. Ideal for heavy-duty applications like industrial gearboxes or large machinery where combined loads are common.
Compliant with RoHS and REACH standards, they offer a balance of strength and durability. Available in standard radial clearance, with options for C3, C4, or C5 clearances to suit different needs.
