In hydraulics and pneumatics, an air cylinder has to match the physical space in your machine, the travel your application needs, and the fittings already on your air lines. The two cylinders in this head-to-head take opposite approaches. One is a compact unit that arrives with M5-to-6mm quick fittings, ready for small-diameter plumbing. The other is a larger SC 63 x 200 with a threaded piston rod built for heavier connections. Their listed prices are $19.37 and $53.89, so the choice also affects your outlay.
Quick verdict
If your work is small-scale and space is tight, the compact cylinder with its included connectors is the more convenient pick. If you need more travel and a heftier port, the SC 63 x 200 is the better fit.
What matters in a pneumatic cylinder
Bore size affects how much force the cylinder can develop at a given air pressure. Stroke tells you how far the piston rod travels. Port size determines which fittings and tubing you can connect. The two cylinders here differ on all three, and each is also paired with different included hardware.
Listed prices and key specs
| Product | Listed price | Price bar | Bore | Stroke | Port |
|---|---|---|---|---|---|
| 16mm Bore 75mm Stroke Pneumatic Air Cylinder | USD 19.37 | 16mm | 75mm | M5 | |
| Pneumatic Air Cylinder SC 63 X 200 | USD 53.89 | 2-1/2" | 7.87" | PT 3/8 |
Where each cylinder wins
- The compact cylinder wins on size, included fittings, and lower listed price.
- The SC 63 x 200 wins on capacity and heavier connection hardware.
One way to frame the decision is by the price bar: the compact cylinder's sits at the lower end of the cost spread, while the SC 63 x 200's is at the top. You are paying for more bore, more stroke, and a larger port design with the SC 63 x 200.
16mm Bore 75mm Stroke Pneumatic Air Cylinder Y Connector and Fitting

This Zaplyte air cylinder uses a double-acting single-rod design in an aluminum-alloy body, and the package includes a Y connector plus two M5-to-6mm quick fittings. That makes it a convenient starting point for small pneumatic systems where you would otherwise have to source connectors separately. It is rated for 0.15-1.0 MPa working pressure, which suits gentle automation and punch-type tasks. The 16mm bore and 75mm stroke keep the overall length manageable, but they also limit how much force and travel you can get. The M5 port is noticeably smaller than the PT 3/8 port on the SC 63, so this model is oriented toward lighter-duty projects with small-diameter tubing.
Pneumatic Air Cylinder SC 63 X 200

The SC 63 x 200 moves up to a 2-1/2" bore and a 7.87" stroke, giving it a much longer range of motion than the compact 16mm cylinder. It also uses a PT 3/8 port and an M16x1.5 threaded piston rod, so the connection points are built for larger pneumatic hardware. The cylinder is listed as new, silver, and with a United States country of origin, with item model number SC 63-200. Because it is a double-acting single-rod cylinder, it can move in both directions, though the longer stroke and wider bore require more installation space. You pay a higher listed price for that extra capacity, but the larger port and rod thread make it a better fit for heavier motion requirements.
Final choice by use case
For compact automation, small punch systems, or any setup where space is tight, the compact 16mm cylinder with its included connectors is the practical choice. When your work calls for longer travel and large-bore capacity, the SC 63 x 200 is the one to pick.
