555 Single Cones (Imperial)

The 555 single cones are tapered roller bearings designed for combined loads, with a 2-inch bore and made from durable chrome steel. They handle dynamic radial loads up to 42900 lbf and static radial loads up to 55700 lbf, suitable for heavy-duty applications.

Their open design allows 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 models, making them a practical choice for replacements. Ideal for use in industrial machinery, automotive systems, and equipment requiring robust load-bearing capabilities.

With standard radial clearance and ABEC-1 rating, they offer a balance of precision and durability. Compliant with RoHS and REACH standards for safe and environmentally friendly use.
