Aerospace and Commercial Bearings - Spherical Bearings & Rod Ends

IS-Clarendon has an extensive stock of high quality aerospace spec v-groove series spherical bearings and rod ends.

Spherical plain bearings are used to accommodate shafts or rods with varying amounts of misalignment. They are designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical-application stress. Most spherical plain bearings consist of a plain bearing and ball bushing inside a lined, cylindrical housing that minimizes friction or provides self-lubrication. Lubrication-free spherical plain bearings are also available.

Rod end bearings are used on the ends of cylinders, linkages, rods, and shafts to take up angular misalignment between connected parts. They consist of a spherically-shaped inner ring and a cylindrical bore for shaft mounting. Metallic rod end bearings are made of brass, bronze, iron, or steel and often plated with zinc or chromium. Non-metallic products are made of plastic, nylon, or Teflon®, a registered trademark of DuPont.

Rod end bearings are used in applications that accommodate low to moderate shaft misalignment. They are also used in many aerospace, military, and automotive applications. Airframe control bearings are usually manufactured in accordance with U.S. military specifications (MIL-SPEC) such as MIL-B-7949 and MIL-B-6039. Rod end bearings with balanced designs are manufactured to meet NAS661, a standard specification for civilian aircraft. In the motor sport industry, rod end bearings are used in steering knuckles and transmission linkages.

All parts are in imperial (inch) sizes. Please contact our sales office for more information.
