GQZ GE55ES Spherical Plain Bearing 55x85x40mm Radial Joint Bearing for Hydraulic Cylinders

Maintenance required, sealed metric radial spherical plain bearings
Radial spherical plain bearings can withstand radial loads, combined radial and axial loads, and misalignment.

This specific design incorporates steel-on-steel sliding contact surfaces with double-lip contact seals on both sides. The bearings require maintenance and can be relubricated through lubrication holes and annular grooves in the inner and outer rings. Designed for radial and combined radial-axial loads; long service life; virtually maintenance-free; suitable for heavy static, alternating, or impact loads.

• Heavy-duty steel-on-steel spherical plain bearing,
• Split outer ring with full grease grooves and lubrication holes
• Optional double-sided 2RS NBR seals against mud, dust and moisture
• MoS₂ coated sliding surface for lower friction
• High static & dynamic load capacity, shock resistant
• Heat-treated bearing steel for long service life

• Heavy industrial machinery
• Mining, crushing, conveying equipment
• Steel mills, paper machines, ventilators
