Hydraulic testing: Each cylinder undergoes hydraulic testing at 350 bars (35 MPa) of pressure.
Terms and conditions: Hydraulic Cylinders are supplied unassembled with feed ports closed with threaded, sealed plugs. Special coatings can be applied on customer request.
Suggested fluid: hydraulic mineral oil, minimum filtration fineness 19/15 a, ISO 4406.
Operating temperature: from -20°C to 80°C. It is recommended to maintain fluid temperatures of 40÷50°C while in operation in order to maximize seal life.
Radial load: prohibited; during use never subject the rod to radial loads.
Welding: Welding on the cylinder’s external diameter should be absolutely avoided.
Coating: when applying a coating to the cylinder with oven drying the temperature should never exceed 80°C. If coating is applied with the rod removed, ensure that the rod is well-protected; before reinsertion remove any coating residue on the rod in order to avoid damaging the wiper and rod seal.
Warning: please refer to the product instructions. The manufacturer, aiming to constantly improve the product, reserves the right to modify the product at any time without prior notice.
