AT Wiper

AT or WM

The wiper-scraper AT consists of two individual wipers, one thin, brass scraper and an elastic wiper ring made of nitrile rubber (NBR).  The two parts are arranged one behind the other and installed in a metal housing.  The inside diameter of the brass scraper is such that the scraper fits perfectly onto the rod after assembly.  The outside diameter of the scraper has sufficient radial play in the housing to be able to compensate for any  mismatch (0.5mm permissible).  When installed, the wiper ring is pretensioned on the rod.

Advantages:

• Simple, open groove

• Easy assembly scrapers are pressed in from the outside

• Good effective wiping, even under extreme conditions

• High abrasion resistance

Operating Conditions:

• Working Temperature: -40°C to 120°C (-22°F to 248°F)

• Speed: = 1 m/s
