Delavan PowerMAX™ PML4008-125ASAE 4.0" x 8" x 1.25" Hydraulic Cylinder. This ASAE Certified Tie-Rod Cylinder has 2,500 PSI Working Pressure and NPT Ports. Delavan PowerMax Hydraulic Cylinders are designed and manufactured to meet the most demanding requirements.

Features:
• Chromed, polished and individually heat-treated shaft provides extended cylinder life
• Built tough enough to stand up to the roughest conditions
• Pins and retainers: high tensile steel, zinc plated to prevent corrosion, comes with cotter pin retainers
• Ports: double ported NPTF for greater flexibility of assembly, unless otherwise stated, cylinders assembled with ports inline
• Piston nut: heavy duty automation grade self locking piston nut holds piston in place under high cycle loading
• Piston: ductile iron, precision machined providing a malleable bearing surface for extended cylinder life
• Piston seal: 90 durometer O-ring with anti extrusion back up washers provide sealing under high load conditions
• Tie-rods: high tensile steel to prevent failure under high pressure
• Cylinder shaft: high strength, hard chrome plated shaft provides extended cylinder life in harsh applications
• Tube: precision finished skive and burnished heavy wall steel tubing for extended seal and cylinder life
• Rod seal: Premium Double Lip Polyurethane BS profile using a double lip design for leak-free performance throughout the pressure range and longer life expectancy
• Rod cap and clevis cap: ductile iron comes with drilled oil passages, offering increased bearing surface for high shock and side load applications
• Rod wiper: Polyurethane AN or D Style provides a tough/hard material to remove contaminants from shaft surface
• Threaded shaft: (on ASAE cylinders) to accept optional mechanical stroke control (not applicable to 5 "bore cylinders)
• Rod clevis: ductile iron able to withstand continuous high load without wear or fracture
• All cylinders are 100% hydraulically tested up to 1.5 working pressure
