Dry running

igus UK says its plastic linear and plain bearings with their chip, dirt and dust resistant capabilities are increasingly used in the machine tools sector.

All plastic bearings from igus are dry-running; they do not require any lubrication and protect against the soiling of grease and oil that can lead to bearing failure. drylin linear bearings are designed to repel particles from the contact surface by the movement itself. As there are no rolling elements, there is nowhere for chips and dirt to become trapped.
