Nordic NTC and NTGC Series telescopic cylinders have provided customers with many years of reliable service guaranteeing long life and low maintenance. Manufactured using ground, polished and chromed . tubing, and assembled with long-lasting polyurethane wipers and seals. Our NTGC series are designed to seal on the outside of each cylinder stage, allowing the tubes to be submerged in oil during retraction. Long overlaps of each stage provide exceptional stability when fully extended while the bolt-on saddle and upper pivot blocks make them simple and easy to install.
