When you're choosing components for hydraulics and pneumatics, an air cylinder often comes down to how much force you need, how far the rod has to travel, and whether the unit can cycle repeatedly without trouble. In compact builds, that balance gets even trickier because space is tight. The Air Cylinder 16mm Bore 300mm Stroke, Mini Air Pneumatic Cylinder Double Action Single Rod is a double-acting pneumatic cylinder with a long 300mm stroke and a small-bore design. The real question is whether this reach-and-compactness combination fits the work you're doing.
Quick verdict
For a light or medium automation project that needs a long stroke in a narrow footprint, this mini pneumatic cylinder is a practical option. The design gives you controlled movement in both directions, and the included fittings reduce the number of loose parts you have to track down. At USD 28.99, it's an approachable entry point for a long-stroke cylinder with a hard-oxidized surface meant to hold up to frequent cycling. It's not built for heavy pushing or clamping, but for positioning, lifting, or reciprocating motions in a small assembly, it deserves a close look.
Who it suits
This cylinder fits hobbyists, makers, and engineers working on small automated fixtures, test rigs, or compact machinery. The M5 port size pairs naturally with small-bore tubing and miniature pneumatic controls. The lightweight build, about 12.6 ounces, means it won't weigh down a delicate frame or z-axis. If you need a cylinder that can extend and retract under air pressure and you have enough space for the full stroke, this package is a reasonable match.
What stands out
The package contents are the most immediately useful feature: one MAL16 x 300 cylinder, one Y connector, and four pneumatic quick fittings. That means you can start routing air lines without sourcing every adapter separately. The cylinder body is made of aluminum alloy and treated with a hard oxidation process, which is aimed at improving wear resistance and cutting down on maintenance. The piston uses a guide-type bi-directional sealing design, so both chambers are sealed to keep the rod moving reliably in either direction. The light 12.6-ounce weight and compact package dimensions of 17.68 x 3.03 x 2.44 inches reinforce that this is meant for tight spaces rather than heavy structural duty.
Air Cylinder 16mm Bore 300mm Stroke, Mini Air Pneumatic Cylinder Double Action
The strongest reason to choose this cylinder is the combination of a 300mm stroke and a compact 16mm bore at a price point that includes useful fittings. The main limitation is the small bore: you won't get high force from 16mm, so if your task requires substantial push or clamp pressure, you may need a larger cylinder. The M5 ports also mean you should confirm your existing air line setup matches before committing.
Meaningful trade-offs
The 16mm bore size is the biggest trade-off to weigh. At typical shop air pressures, a bore this small produces only modest force, so it's better suited to lighter tasks like moving a sensor, shifting a gate, or lifting a small mechanism. The long stroke is generous, but you need to account for the extended rod length in your machine envelope. The package dimensions hint at a fairly long unit, so plan your mounting space accordingly. Since the package contents are focused on the cylinder and fittings, you may need to source mounting brackets or rod-end hardware elsewhere for your setup.
Bottom line
If your project calls for a compact cylinder with a long reach, the Air Cylinder 16mm Bore 300mm Stroke, Mini Air Pneumatic Cylinder Double Action Single Rod is a solid, affordable choice at USD 28.99. It brings together a wear-resistant aluminum alloy body, bi-directional sealing, and a practical bundle of fittings in one package. Just be honest with yourself about the modest force the small bore provides and double-check that your air line setup is compatible. For light to medium automation tasks where stroke length is the priority, this cylinder offers a sensible balance of reach, size, and price.
