Offshore: Hydraulic shock absorber
The worlds biggest shock absorber
The factory at Rissa, formerly Servi Cylinderservice, was established in 1936 and began producing hydraulic cylinders and accumulators in 1956. Since its inception, our products have been used in the world's harshest climate for very demanding work operations.
Servi's factory at Rissa has been producing cylinders since 1956, then known as Cylinderservice. Today, we manufacture cylinders, accumulators and dampers with piston diameters from 20 to 1500 m.m. and with stroke lengths of up to 20 meters - in various material qualities - single and double acting cylinders.
Most of what we deliver is specially adapted to the customer's wishes, but we also have standard cylinders. These have a cylinder configurator that you can use to draw the cylinder as you want it.
We offer overhaul of all types of hydraulic cylinders, of all makes. Our 6 service departments in Rissa, Ski, Kristiansand, Stavanger, Bergen, Ulsteinvik and Trondheim have expertise and equipment for overhauling hydraulic cylinders and accumulators. We carry out honing of cylinders in Kristiansand, Bergen and in Rissa.
The images to the right illustrate the variation in the sizes of our cylinder deliveries. The small cylinder base is placed in the middle of the hole of the large one.
Servi Hybrid Drive is a complete hydraulic cylinder assembled in a compact unit with electrical connection. The cylinder is space-saving, safe and highly energy-efficient.
