QUALITY & EXPERTISE FOR YOUR SEALING NEEDS DESCRIPTION The BECA 320 profile is a U-ring type single acting rod seal with matching lips composed of a profiled polyurethane seal and a NBR O'Ring to preserve its elastic memory. It can be assembled in a groove according to standard ISO 5597. ADVANTAGES Very good sealing at low pressures Elastic memory preserved using the O'Ring Excellent abrasion resistance APPLICATIONS Agriculture Mobile machinery Lifting systems Injection presses Hydraulic cylinders MATERIALS Profiled seal PU 93 Shore A - Blue PU 96 Shore A - Blue High temp. PU 96 Shore A - Beige O'Ring NBR 70 Shore A Other grades of materials are available.
