527 Single Cones (Imperial)

The 527 single cones are tapered roller bearings designed for combined loads, with a 1.75-inch bore and made from durable chrome steel. They handle dynamic radial loads up to 37000 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 are part of the 525 series and come with standard radial clearance, though options like C3/C4/C5 are available.

These cones are interchangeable with Timken models, making them a practical choice for replacements. Ideal for heavy-duty applications such as industrial machinery or vehicle axles where combined loads are common.

Compliant with RoHS and REACH standards, they offer reliable performance while meeting safety regulations. The ABEC-1 rating ensures consistent quality for general industrial use.
