Choosing a pneumatic cylinder for a hydraulics pneumatics project usually comes down to how far the rod needs to travel versus how much push you need at the end of it. The two double-acting cylinders here make that trade-off clear. The Air Cylinder 16mm Bore 300mm Stroke offers a long reach at a lower price, while the 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY offers a wider bore for more forceful motion in a shorter package.
Quick Verdict
If extended rod travel is your priority, go with the 16mm cylinder. It reaches farther than the MECCANIXITY model and costs $5 less. If a wider bore matters more and your travel needs are modest, choose the MECCANIXITY cylinder.
Comparison
| Product | Price | Price Level | Bore | Stroke | Notable Detail |
|---|---|---|---|---|---|
| Air Cylinder 16mm Bore 300mm Stroke | $28.99 | 16mm | 300mm | Y connector and 4 quick fittings included | |
| 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY | $33.99 | 25mm | 150mm | 1.0 MPa max pressure rating |
Where Each Cylinder Wins
The 16mm cylinder wins on reach and hook-up convenience. It travels farther for less money and includes the connector and fittings you'll need, so you aren't sourcing those pieces separately. Its small diameter also suits high-frequency cycling environments.
The MECCANIXITY cylinder wins on bore size and pressure rating. The wider bore gives the piston more surface area, which helps when you need greater force within a relatively short stroke. Its 1.0 MPa maximum pressure rating is a useful spec for planning your air supply.
Product Notes
Air Cylinder 16mm Bore 300mm Stroke

The 300mm stroke is the reason to pick this cylinder. It gives long rod travel in a lightweight 12.6-ounce package, and the bundled Y connector and four pneumatic quick fittings simplify your hook-up. The aluminum alloy body uses a hard oxidation surface treatment for wear resistance, and the piston has a bi-directional sealing design. If your automation project calls for extended motion, this cylinder is the lower-priced way to get it. The trade-off is the 16mm bore: it is a compact diameter, which makes the cylinder more suited to lighter-duty, high-frequency cycles than to heavy-force pushes. For longer reach over a wider range of movement, though, this is the one.
25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY

The 25mm bore is the headline feature here. It provides a larger piston surface than the alternate cylinder, which is beneficial when you need more pushing force in a compact space. The cylinder is rated to a maximum pressure of 1.0 MPa, and its aluminum alloy body is built for smooth operation. It is also a double-acting single-rod cylinder, so compressed air drives the rod in both directions. The main limitation is the shorter stroke length: you get only half the travel of the 16mm cylinder. If your fixture, actuator, or controlled motion needs to move only 150mm or less, this MECCANIXITY cylinder is the stronger choice. If you need long reach, you'll want the 16mm model instead.
Final Call
For a hydraulics pneumatics build that needs maximum rod travel and the lowest price, buy the Air Cylinder 16mm Bore 300mm Stroke. For a build that needs a wider bore and can live with shorter travel, buy the 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY. Match the cylinder to your workspace movement, and the right pick becomes obvious.
