GQZ GE30ES 30*47*22mm High Precision Radial Spherical Plain Bearing | Heavy Load 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.

• Dimensions: ID 30mm, OD 47mm, width 22mm, standard GE radial structure
• Material: Steel-on-steel contact, phosphate coated rings, with grease nipple
• Load: Supports heavy radial load plus moderate axial load, anti-impact & wear-resistant
