Collection: Bearings

Aircraft bearings are built for airframe control systems, landing gear and engine accessories — environments where vibration, misalignment and temperature extremes rule out commercial-grade parts. The category covers airframe ball bearings, spherical plain bearings, rod-end bearings and needle rollers, most with PTFE-lined races or sealed construction for maintenance-free service.

Key families include MS27640-series airframe ball bearings, plain spherical bearings (MS14101 series) and male/female rod ends for flight-control linkages. Races and balls are typically 52100 chrome steel or 440C corrosion-resistant steel; liners are self-lubricating PTFE fabric. Load ratings, breakaway torque and radial play are controlled by the governing military specification, not left to the manufacturer.

Every lot ships with a Certificate of Conformance; heat-lot traceable mill material reports are available on request. Made to order, ships in 4 weeks, delivered duty paid — US duties included in our prices, with free express shipping on orders of $300 or more. Sold by the piece (EA), 1-piece minimum.
