Materials

Fabric NBR 80 Shore A

The cotton fabric is impregnated with a nitrile (NBR) solution to make the hydraulic seals. This material creates a strong wear and degradation resistance. It has a good friction coefficient and is not likely to swell.

Polyoxymethylene - POM

Polyoxymethylene (POM or polyacetal) belongs to the thermoplastics, which have a number of advantages - strong mechanical resistance, good creep strength, high resistance to shocks, particularly at low temperatures, good wear resistance, good sliding coefficient, excellent machinability and good dielectric properties. The low water absorption coefficient, unlike polyamide (PA), also gives this material an excellent dimensional stability.
