When you need a pneumatic cylinder for a fixture, jig, or small automation project, the first question is travel distance: how far does the rod need to push? The next is bore size. These four new double-acting cylinders cover 16mm and 25mm bores, with strokes at 50mm, 75mm, and 150mm, and listed prices from $19.37 to $38.99.
Quick take
The 16mm cylinders in this set are the compact side, with 75mm and 50mm strokes. The 25mm cylinders are the long-travel side, both with 150mm strokes. The lowest listed price belongs to the 16mm/75mm Zaplyte cylinder; the highest goes to the 25mm/150mm cylinder that includes a Y connector and two fittings. If you need a long push, stay in the 25mm row. If the cylinder has to fit in a small space, the 16mm bores are easier to package.

Product notes
25mm Bore 150mm Stroke Double Acting Air Cylinder with Y Connector & 2 Fittings
This is the top of the price range at $38.99, and it pairs a 25mm bore with a 150mm stroke. It has a PT1/8 port, adjustable buffer, aluminum body, and a max pressure of 1.0 MPa. It comes with a Y connector and two fittings, so the extras are part of the package. The tradeoff is the price: among these four cylinders, it is the most expensive listing. If you need 150mm of travel and want the Y connector and fittings in one purchase, this is the option that carries all of them together.
16mm Bore 75mm Stroke Pneumatic Air Cylinder Y Connector and Fitting
At $19.37, this Zaplyte cylinder is the lowest listed price in the set. It has a 16mm bore and 75mm stroke, with a single-rod double-acting design and an aluminum alloy body. It comes with a Y connector and two M5-to-6mm quick fittings, which makes it a strong pick for a compact build. The limitation is travel: if your mechanism needs to move farther than 75mm, this one falls short of the 150mm cylinders. For a small pneumatic setup where stroke is modest, this price and the included fitting set make it a straightforward choice.
25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY
This MECCANIXITY cylinder matches the 25mm bore and 150mm stroke of the higher-priced option, but lists at $33.99. It is suited to pneumatic systems, printing tension control, automation control, and robotics, and it has a maximum pressure of 1.0 MPa and compressed air as the suitable media. If travel length is the priority, this cylinder gives you a long stroke without going to the top of the price range. The tradeoff is the price: at $33.99, it is the second-highest listed price in this group, so the value sits between the lower-priced compact cylinders and the top-priced 25mm model.
Air Cylinder 16mm Bore 50mm Stroke, Mini Air Pneumatic Cylinder Double Action Si
This SWZHAI mini cylinder has the shortest stroke of the four at 50mm, with a 16mm bore and double-acting action. It has high-quality seals and a bidirectional sealing structure to reduce air leakage. It comes with a Y connector and four pneumatic quick fittings. The limitation is stroke length: 50mm is the shortest travel listed here, so it suits precise, small movements rather than long-range pushing. The red finish makes it easy to spot on a busy fixture, and the included fittings add to the practical value.
Final recommendation by use case
- For long travel with the connector/fitting bundle included, choose the 25mm Bore 150mm Stroke Double Acting Air Cylinder with Y Connector & 2 Fittings.
- For the same 25mm/150mm travel at a lower listed price than the top-priced 25mm model, pick the 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY.
- For a compact 16mm cylinder with a 75mm stroke and the lowest listed price, go with the 16mm Bore 75mm Stroke Pneumatic Air Cylinder Y Connector and Fitting.
- For a small red mini cylinder with a 50mm stroke and four quick fittings, choose the Air Cylinder 16mm Bore 50mm Stroke, Mini Air Pneumatic Cylinder Double Action Si.
