Review on Sydien MAL Series 25Mm Bore 200Mm Stroke Double Acting Single Rod Pneumatic Cylinder With Y Connector And 4Pcs Pneumatic Quick Fitting by Dave Rasic

I couldn't move the rod right out of the box. GENERAL. Cylinder disassembled, the rod rotates normally. Finally, it turned out that even with moderate tightening of the top cap, the front part of the cylinder body pressed against the stem, compressing it so much that the stem did not move. He took out the front o-ring and used a round file to remove some material from the edge. Reassembled and now I can move it by hand with the top cap tightened. Tolerances gnaw at it to the point of failure. +1 star because it worked for me in the end. The attached picture is the hole in the rod I had to submit.
