SKF has a long history in sealing knowledge. From our patent on the first automotive wheel seal in 1928, we have evolved to a leading supplier of automotive and truck sealing technology. The demand for increased speeds, higher operating temperatures and synthetic lubricants with aggressive additives increase the stress on oil and grease seals. SKF seals deliver unparalleled performance over a wide range of operating conditions for most automotive and truck applications.
