GE50ES Radial Spherical Plain Bearing 50×75×35mm With Lubrication Grooves For Hydraulic Cylinder Machinery

The GE50ES is an open‑type steel‑to‑steel radial spherical plain bearing, designed for heavy‑duty oscillating joint assemblies. It comes with built‑in lubrication grooves and holes for re‑greasing, providing self‑aligning function to compensate shaft‑housing mounting misalignment. It is widely used for hydraulic cylinders, construction machinery and swing linkage systems where heavy static and oscillating loads are required.

• High static & oscillating load capacity for heavy‑duty engineering applications
• Self‑aligning spherical surface compensates shaft‑housing mounting misalignment
• Lubrication grooves and holes enable periodic re‑greasing for extended service life
• Steel‑on‑steel sliding surface withstands impact and heavy static load
• Suitable for hydraulic cylinder, construction machinery and swing linkage assemblies
• Custom design available (sealed‑2RS version, surface treatment, OEM laser marking)

This bearing is widely used in:

• Hydraulic cylinder joint and piston rod end assemblies
• Construction machinery swing linkage structures
• Metallurgical equipment oscillating connection parts
• Agricultural machinery articulated joint units
