When you buy for hydraulics pneumatics, the hard part is deciding what to buy first. The 2.5x6 Hydraulic Cylinder and the Hydraulic Power Unit 12V Double Acting Pump 6 Quart sit on opposite sides of the system. One is the actuator that moves a load; the other is the power source that makes the fluid move. The right choice depends on what you already have connected. If a pump is already on your machine, you need the cylinder. If you are building a circuit from scratch, you need the power unit to supply flow and pressure.
Quick verdict
If you need an actuator for an existing hydraulic circuit, the 2.5x6 Hydraulic Cylinder at $126.34 is the piece to order. If you need a pump and reservoir that can supply pressure to the rest of the system, the power unit at $160.00 is the one. Start with the side of the system that is missing.
At a glance
| Feature | 2.5x6 Hydraulic Cylinder | Hydraulic Power Unit |
|---|---|---|
| Price | USD 126.34 | USD 160.00 |
| Role | Tie-rod cylinder | Electric pump with 6-quart reservoir |
| Key specs | 2.5" bore, 6" stroke, 2500 PSI, 12,270 lb column load | Electric, gear pump |
| Condition | New | New - Open box |
Where each product wins
- The 2.5x6 Hydraulic Cylinder wins when your circuit already has pressure and you need a tie-rod actuator to do the pushing.
- The Hydraulic Power Unit wins when you need the electric pump, reservoir, and flow source combined in one unit.
Product notes
2.5x6 Hydraulic Cylinder
If your hydraulic circuit already has a pump and reservoir, this tie-rod cylinder is the straightforward actuator to add. Its 2.5" bore and 6" stroke work out to a 16 1/4" retracted length and a 22 1/4" extended length, which gives you real numbers for layout. The 2500 PSI maximum operating pressure and 12,270 lb column load figure show it is meant for pushing work. The trade-off: it only moves when fluid is supplied, so you still need a power unit, hoses, and fittings that match the 3/8" NPT ports. The 1" pin hole size is the other connection point to plan around.
Hydraulic Power Unit 12V
This electric power unit is the flow source for a hydraulic system, with a gear pump and reservoir built into one package. It runs on electric power and is specified for industrial use, making it a practical fit for setups designed around an electric pump. The compact, efficient package is a strength when space is tight. The limitation is the New - Open box condition: the unit was opened before sale even though it is listed as new, so that is the condition you are accepting. It is also only the power side of the system, so you still need a cylinder, hoses, and fittings to turn that flow into motion.
Final choice by use case
If you are replacing the actuator on a system that already has a pump, choose the 2.5x6 Hydraulic Cylinder. If you are starting with only a cylinder and need to create pressure, choose the Hydraulic Power Unit. For a new build where you will eventually need both, buy the power unit first so you have a pressure source while you build, then add the cylinder as the motion end.
