Tie Rod Hydraulic Cylinder, 4.00 Inch Bore, 1.25 Inch Rod Diameter, 8.00 Inch Stroke, 1/2 NPT Ports

For size and basic fit, it matches a 4.00 inch bore, 1.25 inch rod diameter, and an 8.00 inch stroke. Mounting length is 18.25 inches pin to pin retracted and 26.25 inches pin to pin extended, and the ports are 1/2 NPT.

Maximum operating pressure is 2500 PSI, and it's been tested to hold up under both static and dynamic pressure conditions. Plus, the piston rod's induction hardened and chrome plated, so it should resist corrosion even with a lot of use.

For pushing applications, the 1.25-inch rod handles the rated load just fine at the pressures this cylinder operates at. Where you need to pay closer attention is on long-stroke pulling or tension work, and the bigger concern with an 8-inch stroke is column loading on the push side. The specs flag that directly, long stroke cylinders like this one have lower full extension ratings specifically to avoid shaft buckling. The load ratings are built around a pin-to-pin mounting calculation, so as long as you're mounting it that way and keeping the load within the 25,400 pound rating, the rod isn't your weak point. It's induction hardened and chrome plated, and every unit goes through both static and dynamic pressure testing before it ships.
