When you're building or repairing a hydraulic system, the first decision isn't about brand or color-it's about whether you need a part that makes fluid move or a part that moves because of fluid. In the hydraulics and pneumatics world, those two roles are filled by a cylinder and a power unit. They often live in the same system, but they aren't interchangeable. This head-to-head compares the 2.5x6 tie-rod double-acting cylinder with the returned 110V car lift hydraulic power unit to help you choose the component that matches the gap in your setup.
Quick verdict: Choose the 2.5x6 AMRAP cylinder when you need an actuator that pushes and pulls a load with fluid pressure. Choose the returned 110V power unit when you need the pump that supplies that pressure. Both parts work together in a complete circuit, but the right pick depends on whether you already have a pump or a cylinder on hand. The price difference is about $30, with the cylinder at $126.34 and the pump at $155.99.
| Product | Price | Condition | Best For |
|---|---|---|---|
| 2.5x6 Hydraulic Cylinder (2.5\" bore, 6\" stroke, double-acting tie-rod) | $126.34 | New | Turning hydraulic pressure into linear motion |
| Returned 110V Car Lift Hydraulic Power Unit (2.5 gal / 10 qt reservoir, single-acting) | $155.99 | Used | Supplying pressurized fluid to single-acting cylinders |
Where each product wins
- The 2.5x6 cylinder wins if your project needs a linear actuator to move a load. It pairs with a separate pump to create motion.
- The 110V power unit wins if your project needs a self-contained pump. It includes its own motor and reservoir, so it can drive a single-acting cylinder.
The cylinder is new; the pump is used. If you prefer new parts, that's a point in the cylinder's favor, but the pump's condition may still work for your project.
Product Notes
2.5x6 Hydraulic Cylinder 2.5\" Bore 6\" Stroke Double Acting Tie-Rod Cylinder
This AMRAP cylinder is built around a 2.5-inch bore and a 6-inch stroke, with a tie-rod body that's rated to 2500 PSI. Its double-acting design means fluid can extend and retract the rod, giving you power in both directions. The 3/8-inch NPT ports and 1-inch pin hole make it easy to plumb and mount in a range of setups. The main limitation is that it's only an actuator-it won't create pressure on its own. If you don't already have a pump, this cylinder will just sit there. Also, its specific bore and stroke sizes mean you need to match it to your application's travel and force requirements.
Returned 110V Car Lift Hydraulic Power Unit 2.5 Gal /10 Qt Post Hydraulic Pump
This power unit brings together a 110V motor, a 2.5-gallon reservoir, and a pump in one assembly. It spins at 3400 rpm, produces a 1.7 GPM flow rate, and is rated to a maximum pressure of 3200 psi. A strong reason to consider it is that you're getting the motor and reservoir already matched, which simplifies a build. The main limitations are that it's sold as used and returned, and its single-acting function is meant for single-acting cylinders-so it's not a direct match for the double-acting AMRAP cylinder in this comparison.
Final choice by use case
If you're adding an actuator to a machine that already has a power source, the 2.5x6 tie-rod cylinder is the right part. If you're building a lift from scratch or replacing a failed pump, the 110V power unit is the component that will get fluid moving. Match the part to the missing function, and you'll avoid the headache of a system that can't do its job.
