‍At Action Hydraulics, we provide comprehensive hydraulic cylinder repair—from careful dismantling and inspection to precision reconditioning that restores or exceeds OEM standards.

What We Specialize In

• Cylinder Types: Large-bore, high-tonnage, multi-stage, and custom-built cylinders

• Applications: Injection molding, blow molding, extrusion, stamping presses, excavators, cranes, reach stackers, and material handlers

• Brands We Service Regularly: GMK™, Grove™, Liebherr™, Tadano™, Link-Belt™, Krupp™, Husky™, Demag™, Terex™, Manitowoc™, Kobelco™, Hyster™, Taylor™, Hitachi, Caterpillar, Parker, Harris™, and more

Why Choose Us?

• Full-Scope Repairs
We don’t just reseal—we fully diagnose and address the root causes of cylinder failure to prevent repeat issues.

• Complete In-House Machining
Worn or damaged components like pistons, glands, rods, and barrels are precision-machined from scratch in our facility. If a cylinder is beyond repair, we can reverse-engineer and manufacture an entirely new unit—no OEM drawings required.

• Engineered for Longevity
Our repairs often exceed OEM specs, with improved tolerances and surface finishes where performance depends on it.

• Design-Driven Enhancements
When possible, we recommend and implement design improvements to extend service life and make future repairs easier.

Our Process

1. Failure Diagnosis
Every cylinder is disassembled, cleaned, and inspected using precision equipment. We document wear patterns and damage to understand exactly what went wrong.

2. Reverse Engineering & Modifications
Using 3D modeling and CAD, we create detailed designs of worn or missing parts, and store this data for future service. We can replicate entire cylinders from samples if needed.

3. Precision Rebuild and Testing
Cylinders are rebuilt using high-grade components and then pressure-tested under simulated working conditions to ensure reliable performance in the field.
