AY

The function of the PDF Scraper Rings Profile AY is to prevent dust, dirt, grains of sand, or swarf from penetrating into the dynamic rod guidance. This is achieved by a special design which largely prevents scoring, protects the guiding parts and extends the service life of the seals.

The double scraper ring AY closes the rod in the direction of the cylinder. No special screwrings or brackets are required for installation. No close tolerances and no metal inserts are required. The scraper is supplied as a continuous ring and can easily be pressed into the groove recess. In addition, the sealing lip facing the media reduces the residual oil film. The polyurethane compound ensures excellent properties with regard to dry run, increased wear resistance, and extended storage life due to good resistance against ozone and radiation caused by weather conditions.

This special physical material properties offer higher specific forces in comparison with NBR double scrapers.

Application:

Profile AY is designed for axially operated rods in hydraulic cylinders and rod guidances.

Operating Conditions:

• Working Temperature: -35°C to 110°C (-31°F to 230°F)

• Speed: = 1 m/s
