The common way of testing the piston seals of a double acting cylinder is to stop the piston at either end of the stroke, remove the hose at that end and check for leakage. This is full-stroke bypass testing. The trouble with this test is that you are only testing the seals when they are at each end of the cylinder tube where the least amount. In addition to these types, the following methods are quite common : Piston rod eye with swivel or plain bearing, flange on the cylinder head or cap end, trunnion at the cylinder head, cap or centre, and foot mounting. (1) Swivel clevis at cylinder cap (2) Plain clevis at cylinder cap (3) Flange at cylinder head (4) Flange at cylinder cap. Custom Telescopic Hydraulic Cylinder Features & Specifications.
