This plain bearing accommodates angular misalignment between shaft and housing through its spherical sliding contact, transmitting radial load via a curved inner ring running against a PTFE composite sliding layer. The inner ring sliding surface carries a hard chromium coating, giving a low-friction, maintenance-free contact system built to DIN ISO 12240-1, dimension series E, in an open design. Net mass is 0.148 kg. Being maintenance-free, the bearing requires no relubrication and operates without an internal lubricant film that needs replenishing, relying instead on the PTFE composite layer for sliding motion. The open design means it comes without sealing, so protection of the sliding surface from contamination has to be provided externally at the point of installation. Its spherical geometry suits applications where shaft deflection or angular offset must be compensated without inducing edge loading.
