FR Guide Rings
FR guide ring was developed to replace traditional guides in bronze in the hydraulic cylinders. Guide the stem or the piston and avoids metallic contact with the cylinder in the presence of radial forces acting in direction perpendicular to the movement.
Features
• Long service life
• Suitable for both rod and piston guides
• Excellent wear resistance
• Simple assembly and groove design
• Reduces vibrations
• Low friction
• Good resistance to loads
• Good high mechanical stability temperatures
• Easy to install
