Guide rings play an important role in hydraulic and pneumatic cylinders, preventing radial forces from causing permanent damage to the cylinder and seal.
They are used for guiding piston rods and cylinders/pistons.
Advantages:
- Low coefficient of friction
- Good damping of radial vibrations
Operating Conditions:
- Linear speed: up to 5 m/s (PTFE)
- Temperature range: -40°C to +200°C (PTFE + bronze)
Guide strips VO/TR made of PTFE (PTFE + sintering) are used together with guide rings.
