One Bearing for Radial Load and Misalignment: GEC440XS, 440mm Bore, Grease-Fed Outer Ring

GEC440XS is a C‑series large radial spherical plain bearing with an outer ring split axially into two halves and clamped by locking rings. Grease holes in the outer ring feed the steel/steel sliding pair, and the hard‑chrome inner ring stands up to the high pressure found in press rams, shipyard cranes and rolling mill linkages.

• Split outer ring saves dismantling work when the bearing sits in a welded housing
• Grease holes and grooves deliver lubricant directly to the loaded section
• Hard‑chrome inner ring limits wear where contact pressure is highest
• Self‑aligning action absorbs deflection of press frames and crane booms
• 2RS seals keep scale, dust and coolant away from the sliding surface

This bearing is widely used in:

• Hydraulic press main pivots
• Shipyard and port cranes
• Rolling mill stands and shears
• Mining crushers and screen drives
• Heavy industrial linkage points

• 25+ years experience in industrial bearing manufacturing
• Exported to 50+ countries worldwide
