Pneumatic Cylinder, SC63-100, 63mm Bore 100mm Stroke, PT3/8" Port, Air Cylinder Double Action

Good

The product seems great, but these things are heavy yet made from aluminum extrusion, which dents easily. 3 of them were packed in a box with only a little paper thrown in. The box would hold 8-12, so they just bounced around on the trip from Florida to California. All of the edges are dented and a few corners are smashed enough that the counter bore for the mounting bolts is bent inward.They were well wrapped with plastic and bubble wrap to protect from minor scratches and if they had been packed tightly in a smaller box, they would have had far less damage.One piston looks like crap, but the cylinder looks new. It shouldn't effect function. Maybe it sat around the factory and got dirty from being used in some other way and then eventually was assembled with other parts.The Good: these come apart very easily with large snap ring pliers. I will be machining them to stack 3 cylinders to multiply the force, for a power draw bar on my mill. They are well lubed with clear grease and the seals seem good. I have no idea if they are common seals. It will be easy to modify and reassemble these for my project.While I should be able to grind the dents and use the cylinders, they are going on the front of a $10k machining. I wanted them to look nice, not like something bought used. Instead of returning and getting more dented parts, I think I will just make a sheet metal cover to hide this part of the machine, the same way some other manufacturers do.

Asked the seller if they accept return and never got a response.

Manufactured well and heavy duty, I’m sure it’ll last a long time. Installation is seamless with no problems. Performs as expected.

MUY BUEN PRODUCTO EN RELACION PRECIO Y CALIDAD RECOMENDADO

This is well constructed and works as expected. The aluminum is very nicely finished. The threaded ports accepted my quick connects without any issues and the cylinder works nicely. It is pretty small though so just pay attention to the size to make sure it will work for your application.
