BECA 570
Description
The BECA 570 profile is a high-performing, double acting compact piston seal composed of a profiled rubber ring with special fibre reinforcements and a POM wear/back-up ring. It can be assembled in a groove according to standard ISO 6547.
Advantages
Good sealing effect
Excellent extrusion resistance
Excellent wear resistance
Reliable sealing for significant and sudden pressure variations

Dimensions
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.
