What Is a Double-Acting Cylinder?

Double-acting cylinders are cylinders that rely on two ports for working pressure connection lines to provide you with the full power of a hydraulic system from both directions. This versatile cylinder choice provides power in both directions, allowing for a multi-use system that is used in several different implementations. 

While this is a wonderful cylinder choice, double-action hydraulic cylinders do have a complexity that can lead to a few issues. For instance, even a minor leak can compromise the precision of your systems. To avoid this impact, it’s important to work closely with technicians who can provide double acting single stage and double-acting telescopic hydraulic cylinder repair services when you need them most.

Pros and cons

How Is the Double-Acting Hydraulic Cylinder Different from the Single-Acting Hydraulic Cylinder?

Unlike the single-acting hydraulic cylinder, which relies on a plunger that extends when the hydraulic fluid enters the cylinder at high pressure, the double-action hydraulic cylinders operate slightly differently. With this cylinder, the plunger is retracted when the hydraulic fluid enters the system at this high pressure, at the opposite end of the cylinder. This allows the plunger to reset back to its original, retracted position.


What Types of Double-Acting Hydraulic Cylinders Do We Repair?

With over 30 years of experience, our team at Cylinders, Inc. knows how to tackle several different double-action hydraulic cylinder repairs. Let’s break it down.

What Type of Position Sensor Does Your Cylinder Have?

Do you have an electronic, smart sensor cylinder?

Generally, if your cylinder has an electronic plug or port connection, position sensing is in the cylinder. Different OEM and equipment manufactures have proprietary systems, however common systems include:

Welded Cylinders

Welded Cylinders

Welded double-acting hydraulic cylinders rely on bore sizes reaching 24 inches and operating up to 3,000 psi. Unlike other cylinders, this type may require more extensive repairs to maintain the welded cylinder system.

Tie-rod Cylinders

Tie-rod Cylinders

A tie-rod cylinder is held together by four or more threaded tie bolts. These bolts run the length of the cylinder tube and provide power in both extending and retracting directions. This type of cylinder typically has a less expensive repair, with outer tie rods being easier to remove and replace.

Mill-duty Cylinders

Mill-duty Cylinders

Mill-duty cylinders are cylinders that have been designed to provide a more durable, reliable cylinder product. This type of cylinder, due to its construction, helps reduce downtime and maintenance costs.

Telescopic Cylinders

Telescopic Cylinders

A telescopic cylinder is used in situations where an application needs a compact retracted dimension, as well as a longer stroke. Double-acting telescopic hydraulic cylinder repair can be handled by our skilled professionals.
