Custom Aerospace Needle and Roller Bearings

Carter Bearings is a market leading supplier for airframe control needle bearings and aircraft track roller bearings. These style bearings are designed to withstand heavy loads at relatively low speeds. They are commonly manufactured from high carbon chrome steel, AISI 52100 and can be plated with chrome, cadmium or zinc nickel for corrosion resistance. Various stainless steels such as AISI 440C are available for reduced maintenance and increased corrosion resistance.


Over the decades, this expertise has developed into much higher precision and flight critical components. Many precision aerospace roller bearings can be found in gear box systems and in high pressure turbines on main engine shafts. We utilize cutting-edge materials and technologies to add value to every application.


A typical application for track roller bearings is a slat or flap carriage assembly. They can also be found in door guidance systems or for undercarriage component guidance. You’ll find them in many cargo systems as well.
