/866-Single-Cones-(Imperial)-Dimensions.webp)
The 866 single cones are tapered roller bearings designed for combined loads, with a 3.875-inch bore and made from durable chrome steel. They handle dynamic radial loads up to 103,000 lbf and operate smoothly in temperatures from -30°C to 110°C.
The open design allows for easy maintenance, while the steel cage ensures reliable performance. These cones are part of the 855 series and come with standard radial clearance, though C3, C4, and C5 options are available.
Interchangeable with Timken bearings, they are a practical choice for replacements. Ideal for heavy-duty applications like industrial machinery or vehicle axles where combined loads are common.
Compliant with RoHS and REACH standards, these bearings offer a balance of strength and durability for demanding environments.
