1. Heavy‑Duty Pivot Bearing GEC380XS for Large Hydraulic Rams & Metallurgical Equipment

GEC380XS is an extra‑large radial spherical plain bearing with axially split outer‑ring construction, engineered for slow‑swing heavy‑load articulation joints. Its steel‑on‑steel sliding interface paired with hard‑chrome plated inner ring withstands extreme surface pressure, widely deployed in mining shovel linkages, metallurgical machinery and oversized hydraulic rams.

• Axially split outer‑ring greatly simplifies installation and on‑site replacement for massive housings
• Exceptionally high static load capacity designed for heavy industrial pivot applications
• Hard‑chrome‑plated inner ring delivers enhanced wear resistance under high contact pressure
• 4° angular tilt capability compensates frame deformation and assembly misalignment
• Built‑in grease grooves and lubrication ports enable periodic re‑lubrication service

This bearing is widely used in:

• Open‑pit mining shovel & excavator linkage joints
• Heavy‑duty metallurgical mill assemblies
• Oversized industrial hydraulic cylinders
• Offshore deck and marine steering machinery
• Large‑scale heavy‑load pivot articulation points

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