Aerospace series. Bearings, spherical plain, in corrosion resisting steel with self-lubricating liner elevated load under low oscillations. Technical specificationWhat is BS EN 4540 Spherical plain bearings about? BS EN 4540 is a European standard on aerospace series which covers bearings, spherical plain, in corrosion resisting steel with self lubricating liner elevated load under low oscillations. BS EN 4540 specifies the required characteristics, inspection and test methods, qualification and acceptance conditions for spherical plain bearings in corrosion resisting steel, self aligning with self lubricating
