Scraper
A scraper prevents the adhering dirt and dust of the rod from being drawn into hydraulic and pneumatic systems. Scrapers exist in a variety of materials; the most common ones are PTFE (with or without fillers), elastomer and polyurethane.
Scraper A1
The Scraper A1 consists of a PTFE element and an O-ring as preload element. The Scraper A1 has excellent sliding properties, runs stick-slip free and has good media resistance. This is ideal for small installation spaces in opposition with the A2.
The PTFE compound is filled with bronze or carbon graphite to improve the compressive strength. O-rings are available in a variety of different materials.
