Piston Seal MDB 35 x 25 x 16,4/6,3 POM/TPE/NBR

MDB is a five-piece double-acting compact seal which consists of one elastomeric nitrile rubber sealing element, two polyester elastomer back-up rings on both sides to prevent extrusion into the sealing gap, and two special profiled guide rings produced from thermoplastic to absorb transverse forces. APPLICATION: Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery, cranes and standard cylinders. INSTALLATION: Easily assembled into one-piece pistons because the back-up rings and guide rings have been produced in split forms. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil. NOTES: For special applications that require high temperatures, piston seal can be manufactured in FKM and PTFE material.
