A1

The function of the PDF Scraper Rings Profile A1 is to prevent dust, dirt, grains of sand and metal swarf from penetrating into the dynamic rod guidance. This is achieved by a special design which largely prevents the development of chamfers, protects the guiding parts and extends the working life of the seals.

Over sized diameters ensure a tight fit in the groove recess, thus preventing the penetration of foreign particles and dampness.

This scraper ring Profile A1 provides a technically accurate closure at the cylinder; no screwrings and brackets are required. No close tolerances are necessary and no metal inserts. The corrosion which may occur with metal-cased scrapers will be prevented. For the groove recess close tolerances are not required.

Application:

These scraper rings Profile A1 are designed for axially operated rods in hydraulic and pneumatic cylinders, plungers and rod-guidance's.

Operating Conditions:

• Working Temperature: -40°C to 100°C (-40°F to 212°F)

• Speed: = 4 m/s
