Description
Product description
The Scraper A2 consists of a PTFE element with two wiper edges and an O-ring as preload element. It provides excellent sliding properties, runs stick-slip free and shows good resistance to a range of media. The second sealing lip wipes off the residual oil film from the rod. Its compact design is suitable for installations with limited axial space and for heavy dirt contamination. The PTFE compound is filled with bronze or carbon graphite to increase compressive strength. O-rings are available in various elastomer materials.
Fields of application
Main use
applications for hydraulic and pneumatic cylinders
Materials
Technical values
Maximum values for temperature, speed and pressure are not simultaneously applicable and depend on material and media.
