Aurora Differential Bearing Kit

About Aurora Bearing Company

Founded in 1971, Aurora Bearing Company entered the rod end and spherical bearing marketplace and quickly established itself as an industry leader. Aurora built its reputation on a straightforward but powerful commitment: delivering high-quality precision components at competitive prices. Decades later, that philosophy still drives everything the company does.

Aurora's suspension rod end bearings are the heart of the brand's catalog. Also known as "rose joints" or "Heim joints," these components are critical pivot points found throughout vehicle suspension systems — from strut towers and coilover shock ends to 4-link and ladder bar assemblies. Aurora manufactures the world's most complete range of rod end configurations, spanning 2-piece economy commercial designs, molded race construction, and 3-piece precision units. Available in both inch and metric sizes, the lineup includes standard steel, stainless steel, high-misalignment, large-bore, and PTFE-lined variants. Aurora's steel-backed PTFE composite liner series delivers zero clearance, self-lubricating, low-friction performance even under heavy load — a key advantage for demanding suspension applications.

Beyond suspension, Aurora's rod end expertise extends directly into steering. The same precision engineering that makes their bearings excel in 4-link setups translates seamlessly to steering tie rod ends and steering tie rod end assemblies. Aurora PTFE-lined rod ends for steering applications offer notably low friction, controlled clearance, and long service life — qualities that matter whether you're building a race car or restoring a performance street vehicle.

Aurora's influence stretches well beyond the garage. The company supplies aerospace giants like Boeing, Lockheed, NASA, Raytheon, and Northrop Grumman with certified precision bearings, and maintains a full military-spec product line covering rod ends, spherical bearings, and journal bushings. On the motorsports side, Aurora products are found in virtually every discipline — stock cars, sprint cars, drag cars, open-wheel road racers, off-road vehicles, and rally cars. The majority of road race cars manufactured in the United States are equipped with Aurora rod ends as original equipment.

Transportation OEMs depend on Aurora for throttle controls, door actuators, and sway bar linkages on city and over-the-road buses. High-speed rail, motorcycle suspension systems, and even amusement park ride mechanisms count Aurora among their trusted component suppliers. For engineering students, Aurora has supported Formula SAE, Mini Baja, and Formula Student competitions worldwide for over two decades.

Whether you're upgrading a race suspension, rebuilding steering linkages, or sourcing precision rod ends for a demanding industrial application, Aurora Bearing Company brings over 50 years of engineering expertise to every part.
