Review on Baomain Pneumatic Cylinder SC: Optimal Screwed Hydraulics, Pneumatics & Plumbing Solution by Shigg Bigbee

I have bought about 20 of them so far. They're cheap and that's a good thing. I use them in industrial production environments in machines that cycle between full extension and full retraction about 30 times per minute. These cylinders have weak seals and will blow out quickly in this setting. Within a week more than a couple of the cylinders I bought started leaking through the piston ring inside. Two of them started leaking through the shaft seal after a few weeks. What, as they say. There is still a lot of value here. If you buy this size elsewhere, the cost is usually closer to $85. I'm happy with the price of $28. They are also quite easy to disassemble and reassemble using each other's parts. I bought another size of this brand which is used to maintain static pressure for the application. In this case they work fine. In this situation, one of my 12 shaft seals failed. If there is an opportunity for sellers to improve print quality, that would be ideal. In their current form, they are still of decent or high value, depending on need.
