Descripción completa del producto

The double-acting ON rod sealing set featuring a Slipper Seal® design is characterized by minimal break-away and dynamic friction and is therefore also suitable for low-lube conditions. The seal has been designed for housings acc. to ISO 7425-2.
The ON product series is particularly well suited for sealing applications in control cylinders, servo-assisted systems and machine tools.
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.

• 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.
• 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.
• 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:
For high-pressure applications
