No lubrication ever again – thanks to the maintenance-free disc bearings. Proven 1,000,000 times over!


With no need to lubricate the disc bearings, this results in a significantly reduced overall maintenance time. Face seals have been used for decades in road construction equipment where the rollers on the running gear of caterpillar-tracked vehicles have to be effectively sealed and continue to work absolutely reliably under the toughest of operational conditions. The benefits: • Maintenance-free disc bearings with slide seals and life-long lubrication • Maintenance-free stone safety protection via rubber sprung buffer blocks • Disc suspension in pairs for optimised soil contour following and a very good through passage
