The double-acting OE 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 seal design is intended for hydraulic applications. The symmetrical cross section of the sealing ring is designed for uniform return of drag oil during the stroke in both directions. The OE sealing set is particularly well suited for double-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 O-ring (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high temperatures. For hydraulic applications, the piston sealing ring is preferably made from a bronze-filled PTFE compound in order to avoid reliable extrusion resistance. Alternatively, several compounds can be selected, depending on the specific applications profile.
• Good sealing performance in extremely small assembly conditions.
• Can also be used for single-acting applications.
• 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.
• Assembly on one-part piston is possible.
• 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.
• 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
