New slewing bearings from igus use two self-lubricating, low friction polymer sliding elements in place of conventional ball bearings. As a costeffective, low noise alternative, the PRT polymer slew ring bearing modules
Housing parts are aluminium and use stainless steel screws. Polymer sliding pads are made of iglidur J material, which contains a solid lubricant, so it does not require additional lubrication.
