321 Single Cones (Imperial)

The 321 single cones are tapered roller bearings designed for combined loads, with a 1.0148-inch bore and made from durable chrome steel. They handle dynamic radial loads up to 16800 lbf and operate smoothly in temperatures from -30°C to 110°C.

Their open design and steel cage ensure easy maintenance and long service life. The bearings come in standard radial clearance, with options for C3, C4, or C5 clearances to suit different needs.

These cones are interchangeable with Timken bearings, making them a practical choice for replacements. Ideal for industrial machinery or automotive applications where combined loads are common.

Compliant with RoHS and REACH standards, they offer reliable performance in demanding conditions. The ABEC-1 rating ensures consistent precision for general-purpose use.
