This cylinder are made from tested ST-52 tube materials and hard chromed piston rod to sustain impact load. The piston and front cap are made from UV tested materials. Imported seals are used which are made from material such as Nitrile-Butadiene Rubber (NBR), HNBR, PU, PTFE, CR, MVQ, FKM, EPDM, SBR, NR to with stand temperature and pressure. We at Shiv - Shakti did not compromise on seals and we have design experts, who design as per temperature and pressure, which play an important factors for more life of hydraulic cylinder.
