/581-Single-Cones-(Imperial)-Dimensions.webp)
The 581 single cones are tapered roller bearings designed for combined loads, with a 3.1875″ bore and made from durable chrome steel. They handle dynamic radial loads up to 46500 lbf and are built to last in tough conditions.
Their open design allows for easy maintenance, 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, making them 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, they offer a balance of strength and reliability. The standard radial clearance can be adjusted to C3, C4, or C5 as needed.
