Federal Mogul BCA 2255-18 Aetna A-2526-31 Clutch Release Bearing New

This is a new-old-stock Federal Mogul BCA part number 2255-18 clutch release (throw-out) bearing, manufactured in the USA under the Aetna brand designation A-2526-31, as stamped directly on the bearing race. The bearing is covered under U.S. Patent No. 2403480, consistent with Aetna's mid-20th-century self-aligning clutch release bearing design, which uses a floating inner race to compensate for minor misalignment between the clutch fork and pressure plate fingers. The unit features a stamped steel outer housing with a rubber dust seal on the drive face and a machined steel inner race, constructed for mechanical clutch actuation systems on vintage American trucks and heavy equipment. This bearing is new and was sold in a Federal Mogul BCA retail box (box reference R25592), indicating it is genuine Federal Mogul / BCA replacement stock. The BCA 2255-18 is a direct replacement for applications originally specifying the Aetna A-2526-31 clutch release bearing.
