Safety Warning

Fuld produktbeskrivelse

The single-acting OG piston sealing set featuring a Slipper Seal® design consists of a PTFE piston sealing ring and an elastomer O-Ring as a preloading element. The asymmetrical cross-section of the sealing ring is designed for best drag oil performance during stroke in both directions. The OG sealing set is particularly suitable for single-acting pistons in control cylinders, servo controlled systems, machine tools and quick-acting cylinders. Due to the material combination of the slide ring (PTFE) and the O-ring (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Several compounds can alternatively be selected according to the specific application profile.

• Good sealing performance in extremely small assembly conditions.
• Excellent wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.
• Good energy efficiency due to low friction.
• Insensitive to pressure peaks.
• High temperature resistance assured by suitable O-Ring compound selection.
• High extrusion resistance.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-Ring compound selection.
• Dimensions according to ISO ­7425-1.
• Also available as double-acting version.
• Short axial assembly length.
• Installation in closed and undercut housings.
• Available in diameters from 4 to 3000 mm.
• Further dimensions of machined series with short lead times available.

Range of application:
For high-pressure applications.
The OG sealing set is particularly suitable for single-acting pistons in control cylinders, servo controlled systems, machine tools and quick-acting cylinders.
