Choosing a pneumatic cylinder is rarely about picking the cheaper part; it's about matching bore, stroke, and construction to the motion you need. In the hydraulics pneumatics space, two pneumatic cylinder options land within about $1.23 of each other: the Parker Series 2A and the SC32x100. One is a compact industrial cylinder, the other a longer-stroke automation cylinder. Which one fits your machine depends on how much room you have and how far you need to move.
Quick Verdict
Go with the Parker Series 2A if you want a compact, traditional cylinder with a high-pressure rating. Go with the SC32x100 if longer travel and easy maintenance matter more. The real difference is where you can mount them and how far they need to move.

Where Each Product Wins
Parker Series 2A wins when the priority is a compact cylinder with a traditional build. SC32x100 wins when you want longer travel and a lighter unit.
Product Notes
Parker Series 2A 1\" Bore x 2\" Stroke
If your application calls for a compact tie-rod cylinder, the Parker Series 2A is a strong contender. It's a double-acting cylinder with a 1\" bore and 2\" stroke, and it's rated to 250 PSI. The steel construction and tie-rod design give it a traditional industrial feel, and the rod end threads are extra long, which can make mounting hardware easier. The ports are 1/4\" NPT, so it should fit common air lines. The main limitation is the short 2\" stroke, which won't suit anything that needs a longer push or pull. Also, the condition is New - Open box, so the packaging may not be pristine even though the cylinder itself is new. If the size works for your machine, this is a durable, specific option. If you're replacing an old cylinder with the same footprint, this is a direct option.
SC32x100 1-1/4\" Bore x 4\" Stroke
The SC32x100 is aimed at automation jobs where you need more travel. It's a double-acting cylinder with a 1-1/4\" bore and a 4\" stroke, giving you twice the stroke length of the Parker. The aluminum alloy body keeps it lightweight, and the self-lubricating bearing is designed for low-maintenance operation, so you don't have to handle added lubrication. The silver finish and new condition make it ready to install. The trade-off is that the 4\" stroke needs more space than a 2\" unit, so it won't suit a compact machine envelope. If you have the room and want a larger bore with longer travel, this is a straightforward pick. For a simple automation setup, it's an easy cylinder to specify.
Final Choice by Use Case
Choose the Parker Series 2A when you want the traditional cylinder format in a compact footprint. It's the safer call for tight industrial mounts.
Choose the SC32x100 when you'd rather have a lighter, longer-reaching cylinder that needs less maintenance. It's the better fit for automation bays with extra clearance.
If you're still unsure, measure the available mounting space and the required travel first; that will point you to the right one.
