Choosing a pneumatic cylinder for an automation or pneumatic system often comes down to stroke length, bore size, and what you're willing to spend. Here we pit two double-acting units against each other: the larger, more expensive BAOMAIN 5" bore 15" stroke model and the compact, lower-priced MECCANIXITY 25mm bore 150mm stroke option.
Quick Verdict: If your build needs higher force and a longer stroke, the BAOMAIN is the one to look at, given its 5" bore and 15" stroke. If you're working in a tight space and want a lighter-duty unit for smaller loads, the MECCANIXITY, at USD 33.99, is the more practical choice.
| Product | Listed Price | Price Bar | Best For |
|---|---|---|---|
| BAOMAIN Pneumatic Air Cylinder 5" Bore 15" Stroke SC125x380 | USD 77.17 | Long-stroke, larger-force applications | |
| 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY | USD 33.99 | Compact, lower-cost automation setups |
Where Each Product Wins:
- BAOMAIN Pneumatic Air Cylinder 5" Bore 15" Stroke SC125x380 wins on raw dimensions. The 5-inch bore gives it a much larger piston area, and the 15-inch stroke lets it move through a longer distance. That combination suits applications where you need a strong push or pull across a wide travel range.
- 25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY wins on price and footprint. At USD 33.99, it costs $43.18 less than the BAOMAIN, and its 25mm bore with 150mm stroke makes it a more compact component that can fit into tighter assemblies.
BAOMAIN Pneumatic Air Cylinder 5" Bore 15" Stroke SC125x380
For applications that require a bigger push and longer travel, this BAOMAIN cylinder lists at USD 77.17 with a 5" bore and 15" stroke. Its double-acting design powers extension and retraction, and the description notes a self-lubricating bearing to reduce maintenance. The construction is described as high-strength aluminum alloy, which is shared with the MECCANIXITY unit, so you're not sacrificing material durability by choosing the larger model. One thing to consider: the condition is listed as New - Open box, so you may receive a unit that has been opened. Also, the larger bore and stroke mean the cylinder itself is physically bigger, and the listed price reflects that larger capacity.
25mm Bore 150mm Stroke Double Action Pneumatic Air Cylinder MECCANIXITY
The MECCANIXITY cylinder is listed at USD 33.99, making it the lower-priced option between these two. It offers a 25mm bore and 150mm stroke, which suits compact automation systems, printing tension control, and robotics work as described. Its double-acting action and 1.0 MPa maximum pressure rating give it a defined operating range, and the aluminum alloy construction keeps it durable without a big footprint. The trade-off is that the bore and stroke are much smaller than the BAOMAIN's, so it won't handle the same force or travel distances. If you're building something small and cost-sensitive, this is a solid fit; if you need long-stroke power, you'll likely outgrow it.
Final Choice by Use Case: For high-force, long-stroke work where you need the piston to travel over a foot, go with the BAOMAIN. For compact, lower-cost automation where space is tight and loads are lighter, the MECCANIXITY makes sense.
