Choosing a pneumatic cylinder for an automated setup is a bore-and-stroke exercise before anything else. The bore determines how much force the cylinder can develop from your compressed air supply, and the stroke decides how far the rod can push or pull. In hydraulics and pneumatics, those two numbers separate the compact helper from the heavy lifter.
Quick verdict
These two cylinders serve different physical jobs. Pick the Bimba when your machine envelope is tight and your load is modest. Pick the TECHTONGDA when you need a large piston and a long reach.

Where each cylinder wins
Bore size and stroke set these two apart. The Bimba is the smaller unit; the TECHTONGDA is the larger unit. On the basic working principle, neither has an advantage, because both are double-acting with a single rod.
Product notes
Bimba M-0410-DPY
The Bimba M-0410-DPY is a compact air cylinder with a 3/4-inch bore and a 10-inch stroke. It is new open-box stock at USD 39.99 and is made in the United States. In a tight machine envelope, the Bimba keeps the whole assembly small. The 3/4-inch bore is a strength when space is at a premium and the load is light. The trade-off is force: a piston that small has limited surface area, so it is not the choice for heavy pushing. The open-box listing also means the original packaging is not included, which matters if you prefer a factory box. For light actuation in a confined area, the Bimba is a sensible call.
TECHTONGDA SC 100 x 450
The TECHTONGDA SC 100 x 450 is a standard pneumatic cylinder built around a 4-inch bore and an 18-inch stroke. At USD 64.17, it costs USD 24.18 more than the Bimba, but it also covers a larger job. Specs include a piston speed of 50-800 mm/s and an operating temperature range of -20 to 80 degrees Celsius, and the body is described as high-precision aluminum alloy. If you are pushing or lifting a substantial component, the larger piston area gives you more force. The limitation is physical size and higher price: the 4-inch bore and 18-inch stroke make it a much larger cylinder, and the extra cost is hard to justify when a smaller cylinder will do. For bigger loads and longer travel, the SC 100 is the better fit.
Final choice by use case
Choose the Bimba M-0410-DPY when your application calls for a compact envelope and a modest load. Choose the TECHTONGDA SC 100 x 450 when you need a large piston and a longer reach to move substantial components. Your bore and stroke requirements will point you to the only sensible option.
