Scraper seal A1

elastomerNBRmetal

Product description 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 design is ideal for small installation spaces compared to 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.

Fields of application

• static
• dynamic
• single acting
• double acting
• linear
• rotating (inactive)
• oscillating

Main use applications for hydraulic and pneumatic cylinders

Materials elastomers; PTFE with filling material (bronze or carbon graphite). O-ring preload element in various elastomer materials.
