Pneumatic Seal C1
The profile C1 rod seal meets the requirements of the manufacturers of hydraulic and pneumatic equipment for seals with the smallest possible housings. Although crosssections and heights are very small, the sealing performance is excellent. Extremely low friction is experienced because of the short contact of the sealing surface area. Back-up rings or brackets are not required because of the special design. Use in pneumatic equipment is only possible when consistent supply of lubricant such as oiled air is assured. For installation in non-lubricated pneumatic systems (dry air) we recommend our profile E5 which fits into the same housings.
• Good wear resistance.
• Easy installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Installation in closed and undercut housings.
Range of application | |
The profile C1 rod seal is especially recommended for plungers, piston rods, stems and valve lifters as well as for slowly operating pneumatic rotors (v ≤ 0,2 m/s). | |
Operating pressure 1) | |
Hydraulics | ≤ 160 bar |
Pneumatics | ≤ 16 bar |
Rotary transmissions | ≤ 20 bar |
Operating temperature | |
Hydraulics | -35 °C to +100 °C |
Pneumatics | -35 °C to +80 °C |
Sliding speed | |
Hydraulics | ≤ 0.5 m/s |
Pneumatics | ≤ 1 m/s |
Rotary transmissions | ≤ 0.2 m/s |
Recommendation for rotary transmissions: P × v ≤ 3 (Definition see catalogue „Hydraulic Seals“, chapter „Rotary Seals“, introduction). |
Installation
The profile C1 rod seals are manufactured over-sized on the external diameters in relation to the nominal dimensions. This ensures the required tight fit. Only after installation the sealing lip diameter will show the desired dimensions. Profile C1 can easily be snapped into the grooves. When choosing a seal for a particular diameter, it is best to select the one with the largest possible cross-section.
