- Steel garter spring: the garter spring is made from cold drawn steel wire and is designed for superior fluid retention.

SKF invented the first integrated shaft seal in 1928 and has kept pioneering new seal designs and bonding techniques since then. Its seals are made to specific designs using premium materials chosen to suit both the application and its environment. The seal body stays stationary while its sealing lip rides on the rotating shaft. Signs this seal may need replacing include fluid seeping where the shaft exits the case, drips beneath the transmission or transfer case, or a falling fluid level.
