Product Details
80mm Bore Rexroth Hydraulic Cylinders
,ISO 6022 Standard Rexroth Hydraulic Cylinders
,Viton FKM Seals Rexroth Hydraulic Cylinders
CDH1 MF3, 80mm Bore, 56mm Rod, 270mm Stroke, Metallurgical Grade Mill Type Hydraulic Cylinder. CG series Hydraulic Cylinder, double acting mill cylinder, ISO 6022 hydraulic cylinder, heavy duty round body cylinder.
- Viton (FKM) rod and piston seals standard, rated for continuous fluid temperature up to 150°C, compatible with HFA, HFC and HFD fire-resistant hydraulic fluids per ISO 12922
- External metal wiper scraper on rod gland prevents mill scale slag and metallic debris ingress, protecting primary PU rod seal from abrasive wear in dusty rolling mill environments
- Cylinder barrel fitted with thermal radiation shield plate mounting bosses, allowing add-on heat deflector for installations within 2 meters of continuous casting mold zone
- MF3 round flange with 8-bolt pattern, flange face machined flat within 0.02mm, pilot spigot concentricity 0.03mm to cylinder bore axis for rigid alignment-critical mill applications
- Piston rod surface double-hardened: induction case depth 2.0-2.5mm followed by hard chrome 30-50 μm, salt spray resistance 200+ hours for aggressive mill cooling water spray exposure
- Integrated stroke limit proximity switch mounting groove on barrel OD, accepting M12 inductive sensors for end-of-stroke signalling without external bracket fabrication
