Tie Rod Hydraulic Cylinder, 2.50 Inch Bore, 1.13 Inch Rod Diameter, 6.00 Inch Stroke, 3/8 NPT Ports

Description & Features

Rated at 2500 PSI working pressure, this Monarch Industries Tie Rod Hydraulic Cylinder, 2.50 Inch Bore, 1.13 Inch Rod Diameter, 6.00 Inch Stroke, 3/8 NPT Ports is built around a ductile iron piston and head castings with an induction hardened, chrome plated rod. The black finish model features double ported base caps and ports oriented inline with the pin.

Sealing includes a double-acting piston seal with single-acting capability, a double lip U-cup rod seal, and snap-in wiper seals designed to resist contamination and moisture ingress. Rods are tested to a minimum of 90 hours per the ASTM B117-02 salt spray procedure. Every cylinder undergoes static and dynamic pressure testing before leaving the factory.

Pin diameter is 1 inch, with pin-to-pin dimensions of 16.25 inches retracted and 22.25 inches extended. Port connections are 3/8 NPT. Suitable for agricultural and general industrial hydraulic applications requiring reliable double-acting linear force.
