Safety Warning

Full Product Description

The OC double-acting rod sealing set featuring a Slipper Seal® design consists of a PTFE rod sealing ring and an elastomer O-ring as a preloading element. The sealing set has been specifically designed for pneumatic, dynamic applications and enables installation in smallest grooves.
Due to the material combination of the slipper 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. An extensive selection of materials is available for specific application profiles.

• Due to application-optimized geometry and compounds suitable for use in lubricated as well as in oil-free air (after initial lubrication on assembly).
• Good sealing performance in extremely small assembly conditions.
• Can also be used for single-acting applications.
• 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.
• High temperature resistance assured by suitable O-ring compound selection.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.
• Short axial assembly length.
• Installation in closed and undercut housings.
• Available in diameters from 4 to 4500 mm.
• Machined small-volume series and samples available with short lead times.

Range of application:
The OC rod sealing set is particularly suitable for use in pneumatic cylinders, e.g. control cylinders, servo-assisted systems and quick-acting cylinders.
