The double-acting rod sealing set profile ON consists of a PTFE rod sealing ring and an elastomer O-ring as a preloading element. Profile ON is particularly suitable for sealing rods in control cylinders, servo-assisted equipment, machine tools and in quick acting cylinders. The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes this product suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application 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.
• 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 3000 mm.
• Machined small-volume series and samples available with short lead times.
