Description
Description
The Scraper A3 is a rod scraper designed for hydraulic and pneumatic cylinders. It comprises a PTFE element with two wiping edges and an O-ring serving as a preload element. The PTFE compound is available with bronze or carbon graphite fillers to increase compressive strength.
Fields of application
Main use
Designed for use in hydraulic and pneumatic cylinders where heavy dirt contamination and large installation spaces occur.
Materials
Elastomers and PTFE. PTFE variants filled with bronze or carbon graphite. Common elastomer options: NBR, FKM.
Technical values
Variant NBR: Pressure: -; Temperature: -30°C / +80°C (material dependent); Speed: up to 10 m/s.
Variant FKM: Pressure: -; Temperature: -20°C / +200°C (material dependent); Speed: up to 10 m/s.
Maximum values for temperature, speed and pressure are not simultaneously applicable. Values depend on material and media.
