Custom Hydraulic Cylinders for Heavy Industry
Large Hydraulic Cylinders for Presses, Steel Mills, Mining, Aerospace, Hydropower, Shipbuilding, and Industrial Equipment
Macrodyne has been designing and building some of the world’s largest hydraulic press cylinders for decades. But our cylinder expertise is not limited to Macrodyne presses.
We design, manufacture, repair, replace, and modernize large custom hydraulic cylinders for heavy industrial equipment across many industries, including steel, aerospace, mining, defense, shipbuilding, hydropower, rail, energy, construction, rubber, plastics, composites, and more.
We support hydraulic cylinder requirements for all press makes and models, as well as non-press industrial equipment where large-bore cylinders, high force, reliable sealing, and long-term serviceability are critical.
Whether you are replacing an obsolete cylinder, repairing a recurring failure, modernizing older equipment, or designing a new high-force system, Macrodyne can help engineer the right cylinder for the application.
You Do Not Need a Macrodyne Press to Use Macrodyne Cylinders
Macrodyne cylinders are not just for Macrodyne presses.
We support custom cylinder projects for existing equipment, older machinery, legacy systems, and heavy industrial applications where original drawings, replacement parts, or OEM support may no longer be available.
That includes hydraulic presses, but it also includes large industrial equipment used in steel mills, mines, shipyards, hydroelectric facilities, aerospace plants, rail operations, defense production, and other high-force environments.
In many cases, Macrodyne can design a replacement or upgraded cylinder around the existing machine structure, hydraulic system, mounting requirements, stroke, force, operating pressure, and production needs. This is especially valuable when OEM cylinder support is limited or unavailable; the original cylinder is obsolete; the cylinder has been repaired repeatedly; seal failure keeps coming back; rod scoring or chrome damage is recurring, etc.

When the Cylinder is the Problem
A hydraulic cylinder issue rarely stays politely contained. Leaks, scoring, drift, seal failure, inconsistent movement, or repeated repairs can all point to a deeper problem with the cylinder design, loading conditions, hydraulic system, maintenance history, or operating environment.
Macrodyne can help assess the issue and determine whether the best path is repair, rebuild, replacement, or redesign.
Common Cylinder Issues we Help Address :
- Rod scoring
- Chrome damage
- Seal failure
- Packing failure
- Cylinder drift
- External leakage
- Internal bypassing
- Slow or inconsistent movement
- Off-center loading
- Worn barrels
- Damaged rods
- Worn glands or pistons
- Poor surface finish
- Outdated cylinder design
- Recurring cylinder failure
- Obsolete replacement parts
Large Cylinder Applications we Support
From main press cylinders to custom large-bore replacements, Macrodyne supports hydraulic cylinder applications where force, fit, sealing, and long-term reliability have to work together.
Main Cylinders: Main cylinders provide the primary force in hydraulic presses and other high-force equipment. These cylinders must be designed around tonnage, stroke, speed, pressure, mounting, alignment, and long-term service requirements.
Ejector Cylinders: Ejector cylinders help release, lift, or move parts after forming, pressing, molding, or compaction. In production environments, they play an important role in repeatability, part handling, and cycle efficiency.
Pull-Back Cylinders: Pull-back cylinders support controlled return motion and machine reset functions. In demanding applications, they must perform reliably through repeated production cycles.
Cushion Cylinders: Cushion cylinders help control material flow and forming behaviour in deep draw and complex forming applications.
Large-Bore Replacement Cylinders: Large-bore replacement cylinders are often needed when original cylinders are worn, damaged, obsolete, or no longer suitable for the demands of the equipment.
Why Manufacturers Work with Macrodyne
Macrodyne is not just a hydraulic cylinder supplier. We understand the equipment around the cylinder.
That matters because large cylinders do not operate in isolation. They are tied to machine structure, hydraulic pressure, stroke, speed, controls, alignment, loading conditions, safety requirements, maintenance access, and production demands.
A cylinder can look right on paper and still create problems if it does not match the real operating conditions of the machine. Macrodyne brings experience designing and building some of the world’s largest hydraulic press cylinders, custom cylinder design and manufacturing capability and support for all press makes and models.
