iglidur® GKF shafts are perfectly optimised for use in combination with dry-operating plain bearings, and increase the service life of your bearing locations. As an alternative to galvanised or chromed shafts, GKF shafts offer an optimised gas-nitrified shaft surface and a special protection against corrosion and wear. They have been developed especially for the use in agricultural and forestry machines as well as for construction machinery and utility vehicles.
