The CR double-acting rod sealing set featuring a Caveseal design consists of a PTFE rod sealing ring and an elastomer O-ring as a preloading element. The sealing set is suitable for dynamic applications as an alternative to an O-ring in situations requiring optimum sealing performance and friction. The Caveseal design 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.
• 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.
• Assembly on one-part piston is possible.
• 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.
• Short radial assembly depth.
• Installation in closed and undercut housings.
• Available in diameters from 4 to 4500 mm.
• Can be used in existing O-ring grooves.
• Additional sizes of machined products available on short notice.
Range of application:
The CR rod sealing set has been designed to replace standard O-rings. For dynamic applications we recommend our OA product series for pneumatic applications and ON or OE for hydraulic applications.
