- 4-inch stroke extends to 18 1/4 inches for full range
- 5-inch rod with 1-inch pins fits standard mounts
Chief 287029 Welded Cylinder
The Chief 287029 is a welded hydraulic cylinder built for double-acting linear force in industrial and mobile machinery. It suits maintenance teams and equipment builders who need a compact 3-inch bore unit with a 1.5-inch rod for push and pull cycles.
Sustained Load Behaviour
Rated to 3,000 psi maximum pressure, the cylinder maintains sealing integrity through full 4-inch stroke cycles without pressure drop. The welded body construction resists side-loading distortion during continuous operation, while the 1-inch pin diameter at each end distributes joint stress evenly across the 14 1/4-inch retracted and 18 1/4-inch extended lengths.
Deciding Specification
The #8 SAE port size determines hose and fitting compatibility for the hydraulic circuit. Installers must match this port thread to existing plumbing or adapt it, otherwise the cylinder cannot be connected to the system.

Questions about this item
How much hydraulic power does the 3,000 psi cylinder consume when running continuously?
The cylinder converts hydraulic pressure into linear force; actual power draw depends on your pump and system flow rate rather than the cylinder itself.
Which hydraulic fittings and pins are required to install the #8 SAE ports and 1 in pin holes?
You need #8 SAE O-ring boss fittings for the ports and 1 in diameter pins for the clevis mounts; clips are included with the cylinder.
Will the 14 1/4 in retracted length fit the same mounting points as my current 3 in bore cylinder?
If your existing cylinder has the same 14 1/4 in retracted length, 1 in pin diameter and #8 SAE ports, it will bolt in directly.
