BECA 301/AE
Description
The BECA 301/AE profile is a single acting compact rod seal composed of a profiled fabric NBR seal and a POM back-up ring on the back. It can be assembled in a groove according to standard ISO 5597.
Advantages
Optimised sealing effect
Good chemical compatibility, depending on the material chosen
Excellent wear resistance
Excellent extrusion resistance

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.
