GKF wear rates

Wear comparison: abrasion after 200,000 cycles with different iglidur® bushings on test shafts with hard-chrome, GKF and galvanised surface p = 30N/mm²; v = 0.01m/s, pivoting movement.

Due to the corrosion-protected surface no additional lubricants are required

igus supports the circular economy of plastics and is investing in chemical recycling. Learn more about this topic.

Ideal for plain bearings - iglidur® GKF shafts

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.

The advantages of iglidur® GKF shafts

3 times lower wear compared to galvanised and chrome-plated surfaces
Surface hardening and corrosion protection are produced in the same process
Corrosion protection reduces the risk of failure and wear
Weldable without additional machining
Greatly improved coefficient of wear compared to conventional shaft materials

Areas of application:
highly stressed external bearing points in construction machinery or commercial vehicles, as well as agricultural machinery for tillage and harvesting.

"We were looking for a material that was lubrication-free, robust and cost-effective, so we opted for the iglidur plain bearings from igus."

Klemens Ollmaier, Managing Partner of samo Maschinenbau GmbH

Harvester with iglidur plain bearings

"In addition, we were looking for a bearing that did not require lubricants, because the farmer did not want to lubricate as in the very dusty environment this would quickly lead to strong dirt adhesion."

Jochen Gnann, Director Supply Chain at AGCO Feucht

"The wear on the brass bushes was too high. Therefore, we were glad that the polymer bearings finally provided an effective alternative, because the plastic bearings are simply more robust."
