Heavy Duty High Tonnage Hydraulic Cylinder for Structural Lifting Hcr-80012

To find the right size, you need to know how much weight you want to lift. You must check the "bore size" (the inside width of the tube) and the oil pressure. A bigger bore can lift more weight. You also need to measure the "stroke length," which is how far the rod needs to move.

A good cylinder can last for 10 to 15 years or even longer. It depends on how often you use it and how well you clean it. If you change the oil and seals regularly, it will work for a very long time.

High-strength alloy steel is the best for most heavy jobs because it is very strong. However, aluminum is the best if you need a light tool to carry. For wet places where things rust easily, stainless steel is the top choice.

A 10,000 psi system is very powerful. For example, if you use a small cylinder with a 2-inch bore at this pressure, it can lift about 31,000 pounds (over 15 tons). The more area the oil pushes against, the more weight it can lift.

This usually happens because the oil flow is too low or there is air trapped inside the cylinder. You should also check if the oil filter is dirty or if the pump is old.
