  • 产品名称: ROD SEALING SET PRAEDIFA SERIES CR, CAVESEAL®
  • 浏览次数: 40

The double-acting Caveseal® rod sealing set profile CR consists of a PTFE rod sealing ring and an elastomer O-Ring as a preloading element. The sealing set is appropriate for dynamic applications as an alternative to an O-Ring, for situations where sealing performance and friction have to be optimized. 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.
• 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 3000 mm.
• Can be used in existing O-ring grooves.
• Additional sizes of machined products available on short notice.

Range of application
The CR profile range has been designed exclusively to replace standard O-Rings. For dynamic applications we recommend our ON profile range.
