Suitable for high loads or vibration levels, Aurora Bearing offers three metric rod end series to prevent excess clearance from the deformation of the softer race material on bearings built to previous specifications. Aurora MM-M and MW-M series parts are made with a low carbon steel raceway instead of brass, bronze, or copper, offering improved ball/race durability and load capacity. For vibratory applications where demands are placed on the bearing itself, the Aurora KM-M and KW-M series offer a heat-treated alloy steel raceway around the steel ball in a low-carbon steel body. For demanding applications with high loads and vibratory conditions, the AM-M and AW-M series feature heat-treated raceway bearing construction and a heat-treated alloy steel body. All series feature improved self-lubricating and long life service.
