This spherical plain bearing accommodates angular misalignment between shaft and housing through a curved sliding contact between the inner and outer ring. The inner ring has a hard chromium-coated spherical surface running against a sliding layer of PTFE composite, giving maintenance-free operation without external lubrication. Construction follows DIN ISO 12240-1, dimension series G, open design, without seals. Net mass of the bearing is 0.035 kg. Since the bearing is maintenance-free and requires no relubrication, it suits applications where access for servicing is limited or where oil or grease lubrication is undesirable. The open design without sealing means the sliding surfaces are exposed, so protection against contamination must be provided externally. The spherical contact geometry allows the bearing to compensate for shaft deflection or misalignment while maintaining full contact across the sliding layer.
