## Abstract

A high load capacity bearing that includes a cylindrical outer sleeve that fits around a separable cylindrical outer race assembly. The outer race assembly includes a set of non-helical grooves formed on its inside surface that mesh and engage teeth formed on the outside surface of a plurality of rotating rollers that are longitudinally and axially aligned inside the outer race assembly. The rollers are longitudinally aligned and evenly space apart and rotated as a unit inside the outer race assembly. Located inside the rollers is an inner race with non-helical grooves formed on its outside surface that mesh and engage the teeth on the rollers. The inner race includes a smooth inside bore that fits around the support surface on a shaft.
