Choosing a pneumatic cylinder often comes down to matching bore, stroke, and price to the force and travel your mechanism needs. Too small a bore means the cylinder stalls under load; too short a stroke means the work piece doesn't reach its destination. This comparison walks through four pneumatic air cylinders that span just over $52 in listed price, from compact 16mm-bore minis to a 5-inch industrial unit, so you can see which one fits your build.
Quick Take
- Need a compact cylinder? The 16mm x 50mm mini is a small, short-stroke choice.
- Need longer reach? The 16mm x 300mm version adds travel to the same slim bore.
- Want a mid-size option? The Bimba M-0410-DPY has a 3/4-inch bore and 10-inch stroke.
- Need serious force? The Baomain SC125x380 has a 5-inch bore and 15-inch stroke.
Price Comparison
| Cylinder | Listed Price | Price Bar | Best Fit |
|---|---|---|---|
| 16mm x 300mm Mini | $28.99 | Compact long-stroke movement | |
| 16mm x 50mm Mini (SWZHAI) | $24.37 | Short-stroke, tight-space automation | |
| Bimba M-0410-DPY (3/4" Bore x 10" Stroke) | $39.99 | Mid-size cylinder | |
| Baomain SC125x380 (5" Bore x 15" Stroke) | $77.17 | Heavy-duty, long-travel positioning |
Decision Matrix
- Light bench work or quick cycling: The SWZHAI 16mm x 50mm offers the shortest stroke and lowest listed price, making it a straightforward fit for small stops, clamps, or solenoid-driven prototypes.
- Need more travel in a small envelope: The 16mm x 300mm mini keeps the same bore but has six times the stroke of the 50mm model, so it suits sliding gates or pick-and-place arms where space is tight but reach matters.
- Mid-size automation: Bimba M-0410-DPY is a single-rod cylinder with a 3/4-inch bore and 10-inch stroke, good for feed mechanisms and light presses when you don't want a large chassis.
- Heavy positioning: Baomain's 5-inch bore and 15-inch stroke gives you a large piston area and travel for moving substantial loads, such as press platens or conveyor diverters.
Product Notes
16mm Bore 300mm Stroke Mini Air Cylinder
This pneumatic cylinder combines a 16mm bore with a 300mm stroke, giving you a long reach from a narrow 12.6-ounce package. The aluminum alloy body, hard-oxidized surface, and bi-directional sealing design are aimed at high-frequency cycling, and the kit includes a Y connector plus four pneumatic quick fittings to help you get it hooked up. Its real strength is stroke length: if your mechanism needs to move a few hundred millimeters but the surrounding frame is slim, this unit fits that niche. The trade-off is force. A 16mm bore is a small piston area, so you should not expect to push heavy loads. It's a reach-focused cylinder, not a power house.
16mm Bore 50mm Stroke Mini Air Cylinder (SWZHAI)
This is the shortest-travel cylinder in the group at 50mm, and its compact size fits into tight panels and fixtures. The bidirectional sealing structure helps keep the piston less prone to air leakage, and the package includes one cylinder, one Y connector, and four pneumatic quick fittings for basic hookup. It comes in red, which can help you spot it in a crowded manifold. The obvious limitation is travel: a 50mm stroke won't work for linear motion spanning a long distance. If your application only needs a few centimeters of movement, this mini gives you a solid short-range push in a small package.
Bimba M-0410-DPY Double Acting Pneumatic Air Cylinder
Bimba's M-0410-DPY is a double-acting, single-rod cylinder with a 3/4-inch bore and a 10-inch stroke, putting it in the mid-size range of this lineup. It comes from the United States and is listed as new without original packaging, which means you're buying the cylinder itself rather than a retail box. The construction is built around compressed air and standard double-acting behavior, so it extends and retracts under air pressure. This is the cylinder to choose when you need more force than a 16mm mini can generate but don't want to jump to a 5-inch industrial block. The main drawback is the open-box condition: no factory packaging is included.
Baomain Pneumatic Air Cylinder 5" Bore 15" Stroke SC125x380
Baomain's SC125x380 is the biggest unit in this comparison, with a 5-inch bore and a 15-inch stroke. It is the only model with this kind of piston area and travel. It is a standard double-acting cylinder with an aluminum alloy body, a self-lubricating bearing for low-maintenance operation, and a metal construction that suits demanding industrial automation. This is the cylinder to pick when your load is large or your travel is long and you need controlled force in both directions. The limitation is its footprint: at 5 inches across and 15 inches of stroke, it is not a compact component.
Final Recommendation by Use Case
- For a short-stroke project with the lowest listed price: the SWZHAI 16mm x 50mm at $24.37 gives you a compact cylinder with basic hookup parts.
- For long reach in a slim space: the 16mm x 300mm mini at $28.99 stretches a small bore across 300mm of travel.
- For a mid-size, US-made cylinder: choose the Bimba M-0410-DPY at $39.99 if open-box packaging isn't a deal breaker.
- For maximum force and travel: the Baomain SC125x380 at $77.17 is the one to specify when nothing smaller will move the load.
