GQZ GE140ES-2RS Radial Spherical Plain Bearing 140×210×90mm With Double Rubber Seals For Hydraulic Equipment

GE140ES-2RS is radial spherical plain bearing. ES represents steel-on-steel sliding contact surface with phosphating treatment; 2RS stands for double-sided rubber sealing structure. It can withstand radial load together with moderate bidirectional axial load. The spherical sliding surface allows large angular deflection, compensating shaft misalignment, swing and oscillating motion. Widely used for hydraulic cylinders, construction machinery hinges, lifting equipment and engineering machinery articulated assemblies.
