420mm Bore GEC420XS Radial Joint Bearing for Port Cranes and Heavy Presses Spherical Plain Bearing

1. Product Overview
GEC420XS is a C‑series large radial spherical plain bearing whose outer ring is split axially and held by locking rings. Grease grooves and lubrication holes sit in the outer ring, and the steel/steel sliding pair with a hard‑chrome inner ring carries heavy radial load in slow oscillating joints such as press rams, port crane linkages and mill equipment.

• Self‑aligning geometry compensates housing distortion in large welded structures
• 2RS double‑sealed variant blocks dust, scale and coolant from the sliding pair
