EE128112 Single Cones (Imperial)

EE128112 Single Cones (Imperial)

The EE128112 single cone is a tapered roller bearing designed for combined loads, with an 11.0236-inch bore and made from durable chrome steel. It handles dynamic radial loads up to 195,000 lbf and operates smoothly in temperatures from -30°C to 110°C.

Its open design allows for easy maintenance, while the steel cage ensures reliable performance under heavy loads. The bearing is interchangeable with Timken models, making it a practical choice for replacements.

This cone is part of the 128000 series and comes with standard radial clearance, though C3, C4, and C5 options are available. Ideal for industrial machinery and heavy equipment where robust performance is needed.

Compliant with RoHS and REACH standards, it offers a balance of strength and durability for demanding applications. The effective center location of 0.26″ helps maintain alignment under load.
