GAC170F Maintenance-Free Joint Bearing for Heavy-Duty Swing and Tilting Motion

GAC170F is a self-lubricating angular contact spherical plain bearing built for hinge points that see both radial force and one-direction axial thrust. The steel/PTFE fabric sliding pair removes the need for routine greasing, which suits equipment that is hard to reach for maintenance.

• Runs without grease — PTFE fabric liner keeps friction low from the first stroke
• Handles combined radial load and one-way axial load in a single hinge point
• Separable inner and outer rings simplify mounting and replacement on site
• Self-aligning action absorbs shaft deflection and frame distortion
• Hardened GCr15 rings resist wear under repeated oscillating motion

This bearing is widely used in:

• Hydraulic cylinder rod ends
• Engineering and construction machinery
• Mining and metallurgy equipment
• Automotive steering and suspension linkages
