Safety Warning

Full Product Description

The single-acting OD rod sealing set featuring a Slipper Seal® design consists of a PTFE rod seal and an elastomer O-ring as a preloading element. The asymmetric cross-section of the seal has been designed for optimum return of drag oil during the stroke in both directions. The optimum sealing effect is achieved by installation in a tandem arrangement in combination with a double wiper ring. The OD product series is particularly well suited for piston rods in control cylinders, servo-assisted systems, machine tools and quick-acting cylinders. The sealing set is successfully used in the automotive industry (e.g. in shock absorbers) and the process industry as well. 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 alternative compounds may be selected depending on 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 ¬7425-2.
• Also available as double-acting version.
• Short axial assembly length.
• Installation in closed and undercut housings.
• Available in diameters from 4 to 4500 mm.
• Further dimensions of machined series with short lead times available.

Range of application:
