Customization and inspection
 

1.I have a sample on hand, how do i know what size?
Measure the outer diameter of the cylinder, then measure the length between pin holes (with the center rod pushed all the way in to the cylinder) to get the approximate push/pull length, then measure the diameter of the push/pull rod. If you have a pin in the attachment points, measure the diameter of the pin (usually 3/4 inch or 1 inch diameter).This will give you a reading of something like a cylinder (3 inches inside) for 3 1/4 inches outside, type of attachment points, size of pins, and overall push/pull length (50 inches). The cylinder may be a 3 inch cylinder with 1 inch pins and be 50 inches overall, and maybe then you can choose different lifting, pulling, or pushing weights like 5000 pounds, etc. This is only an example of cylinder measurements; they can be bigger, smaller, shorter, have a lower weight capacity, etc.I hope this helps you out.

2.How do I know what size to order?
Four ways. 1) Send us the drawing if you have one; 2) Measure the size of the sample if you have one; 3) Send us a sample if possible; 4) Look closely at the chart; the retracted length must match what you have; the extended length may vary a little. The rod size is the shaft that moves in and out; you can see and measure that; the bore is the inside of the main housing that you can't see or measure unless it's apart. Order mainly by length, not bore and stroke, then get the rod size as close as you can, and the bore size should work out right.

3.What is the difference between double acting and single acting cylinders?
Double-acting: have a port at each end, supplied with hydraulic fluid for both the retraction and extension.Single-acting: hydraulic fluid enters through a port at one end of the cylinder, which extends the rod by means of an area difference. An external force or gravity returns the piston rod.

4.What colors are available?
Red, black, others as required.

5.Can we design our own package or print our own logo?
Yes! Package and logo will be made according to your requirements.

6.Do you have quality control system?
