1. Product Overview GE180ES-2RS is heavy-duty radial spherical plain bearing. ES stands for steel-on-steel phosphated sliding contact surface; 2RS refers to double-sided lip rubber sealing structure. Its spherical sliding interface allows large angular deflection to compensate shaft misalignment. It can bear heavy radial load and moderate bidirectional axial load simultaneously. Perfect for oscillating, tilting and low-speed rotating movements. Widely adopted on excavator
