Description

This plain bearing accommodates angular misalignment through a curved sliding contact between the inner and outer ring. The inner ring has a hard chromium-coated curved surface running against a PTFE composite sliding layer, giving maintenance-free operation without external lubrication. It is built to DIN ISO 12240-1, dimension series E, in open design, with a net mass of 0.066 kg. The open design means no seals are fitted, so the sliding surfaces stay exposed to the surrounding environment and require a clean installation area free of contaminants. As the design is maintenance-free, no relubrication is needed once mounted. The curved inner ring surface allows the bearing to compensate for shaft misalignment, and the PTFE composite layer keeps friction low without grease or oil supply.
