Self-Lubricating GAC180F Spherical Plain Bearing for Hydraulic Cylinders

The GAC180F Angular Contact Spherical Plain Bearing is a self‑lubricating plain bearing designed to carry combined radial and unidirectional axial loads. It adopts steel/PTFE fabric sliding contact surface, maintenance‑free structure, widely used for heavy‑duty swing and tilting motion applications.

• Maintenance‑free design with PTFE fabric liner, no regular greasing required
• Capable of bearing combined radial and one‑way axial load
• Low friction coefficient and stable sliding performance
• Self‑aligning design to compensate installation error
• Separable inner and outer rings for easy mounting
• Good wear resistance and long service life under heavy load
