Tie Rod Hydraulic Cylinder, 4.00 Inch Bore, 1.25 Inch Rod Diameter, 12.00 Inch Stroke, 1/2 NPT Ports

This hydraulic cylinder is rated for a maximum operating pressure of 2500 PSI, with a pressure rating of 1550. It's built for heavy-duty applications, able to handle a rated load of 19,600 lbs.

For pulling applications it works just fine, but the rod diameter does affect how much load you can safely push at full extension. Long stroke cylinders like this one carry a lower full extension rating specifically because of column loading, which is basically the risk of the rod buckling under compression over a longer span. The rated load of 19,600 lbs is based on a pin-to-pin mounting calculation, and the manufacturer recommends a minimum safety factor of 2 when figuring your maximum pushing load. So if you're running this thing near full extension under heavy push loads, back off and work within those column load tables rather than relying on the headline rated load number.

Port size matches 1/2 NPT on this cylinder, so it is set up for 1/2 NPT fittings on both ends.
