Sealing system: Double rod seal, main one in PTFE + Bronze and secondary one in polyurethane. Piston seal in PTFE + Bronze with energizing ring in NBR90 and anti-extrusion rings in PTFE. Rod and piston seals in phenolic resin. O-rings in NBR70, Anti-extrusion rings in polyester.
Hydraulic testing: Each hydraulic cylinder undergoes hydraulic testing at 350 bars (35 MPa) of pressure.
Terms and conditions: 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: any welding of accessories on the cylinder plug or the rod ends must be done after having completely removed the rod. Before reinserting it, make sure the welds are cooled off. Preheat the rod 200°C and use multipass welding to avoid overheating material; protect chromed surfaces adequately from welding spit. 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.
