Engineered & Built to Your Exact Specifications
Your custom cylinder is built exactly to spec with no middlemen and no miscommunication. Hydramachine handles the complete process from initial specification review through final pressure testing, all in our 12,000 sq ft Loveland, Ohio facility.
Whether you have detailed engineering drawings or just a failed cylinder and a description of what you need, we'll work with you to define every dimension, material, and performance requirement before fabrication begins.
When You Need a Custom Cylinder
Standard catalogs can't cover every application. Here are the most common reasons our customers need custom-built cylinders:
Obsolete OEM Cylinder — Your original cylinder is no longer available from the manufacturer. We reverse-engineer and build a direct replacement.
Non-Standard Dimensions — You need bore, stroke, or mounting dimensions that don't exist in standard catalogs.
Special Materials or Coatings — Your application requires specific materials, coatings, or seal configurations for harsh environments.
New Equipment Build — You're building or modifying equipment and need a cylinder designed for a unique application from scratch.
Unique Spec Combination — Standard catalogs don't offer the specific combination of bore, stroke, pressure rating, and mounting you need.
Our 5-Step Build Process
Every custom cylinder goes through a controlled, documented process from specification to final completion.
Specification Review
You provide drawings, dimensions, the failed cylinder itself, or a description of the application. We work with whatever you have.
Engineering & Design
Our team defines bore, stroke, rod diameter, pressure rating, mounting style, port locations, and seal configuration to meet your requirements.
Material Selection
Top-grade materials selected for your operating environment. Honed tubing, hard-chrome rod, precision-machined heads and pistons.
In-House Fabrication
Every component is machined and assembled in our facility. No outsourcing. Complete control over quality and timeline.
Pressure Testing & Final Verification
The finished cylinder is test-cycled at operating pressure to verify function, seal integrity, and performance before completion.
In-House Fabrication in Action
From large-capacity turning to close-tolerance milling and custom modifications, these fabrication stages are completed in our shop with full quality control.
