Advantages Guide Ring
- The tapes can be supplied either cut to length or by the meter, to be cut according to requirement.
- High load capacity (compressive strength), low wear and reduced friction due to an additive of carbon to the PTFE material.
- No tendency to stick-slip in the case of low sliding speed.
- Available in practical dimensions.
- Simple groove designs.
- Simple piston designs without metallic contact of the sliding surfaces.
- Profile geometry which is exactly suited to work in lubricated air as well as dry and oil-free air.

Profiles Guide Rings
PROFILE G1For pneumatic applications G1 and G2 are used for bearings where it is imperative that the system pressure is carried on the seals. They are designed as open bearings with a well defined gap. |
PROFILE G2For hydraulic applications G1 and G2 are used for bearings where it is imperative that the system pressure is carried on the seals. They are designed as open bearings with a well defined gap. |
PROFILE G3For hydraulic applications G3 is a closed bearing, which in certain applications is used as a combined seal and bearing. |

Back-up Rings
Back-up rings are used for static and dynamic applications in connection with O-rings, to prevent extrusion of the O-ring into the diametrical clearance.
Rotary Seals
Rotary seals are used in applications with oscillating or rotating movements in order to retain liquid lubricants and to prevent the penetration of dirt and water.
Rod Seals
The Rod Seal consists of a single-acting PTFE rod sealing ring and an O-ring. They are combined as a single unit and are appropriate for rods and plungers in hydraulic cylinders.
