product description Series: RR series Product line: Long stroke hydraulic cylinders Collar thread and plunger thread for easy fixing Enamel paint for improved corrosion resistance Removable hardened saddle protects the plunger during lifting and pressing Built-in safety valve prevents accidental overpressure Plunger wipers reduce contamination and extend cylinder life Integral stop ring provides piston blowout protection Double acting, hydraulic return Hardened and chrome-plated pistons reduce wear and corrosion Hardened alloy steel guide rings eliminate overtravel and provide support to reduce wear from eccentric loads High-strength composite bearings provide support for eccentric loads without damaging the cylinder wall Think safe The manufacturer's load and stroke ratings are maximum safe limits. Good practice encourages using only 80% of these ratings!
