This plain bearing accommodates angular misalignment between shaft and housing through a spherical sliding contact between the inner and outer ring. The sliding layer is a PTFE composite, while the curved surface of the inner ring carries a hard chromium coating, giving a low-friction, maintenance-free running pair. Design follows DIN ISO 12240-1, dimension series E, in open (without sealing) configuration. Net mass is 10.76 g. Because the sliding layer is maintenance-free, no relubrication is required during service, which simplifies installation where access for regreasing is limited. The open design without sealing means the bearing relies on the sliding surface pairing alone for protection, so it should be shielded from contamination in the application. The spherical geometry compensates for shaft deflection and misalignment, making it suitable where angular movement between mating parts must be absorbed without introducing rolling elements.
