Custom Hydraulic Cylinders
Standard hydraulic cylinders are not always suitable for demanding equipment or specialized operating conditions. PSI Hydraulics manufactures custom hydraulic cylinders engineered around the specific mechanical, dimensional, and hydraulic requirements of each application. As an experienced hydraulic cylinder manufacturer, we provide custom cylinder fabrication for new equipment, OEM replacement, and reverse-engineered cylinders when original components are obsolete or unavailable.
Overview
Custom hydraulic cylinders are designed for applications where standard catalog products cannot satisfy the equipment's operating requirements. Mounting configurations, bore and rod dimensions, stroke length, pressure ratings, environmental conditions, and available installation space often require a cylinder engineered specifically for the application rather than adapted from an existing design.
PSI Hydraulics manufactures custom hydraulic cylinders for OEM equipment, industrial machinery, mobile equipment, and replacement applications. Projects may begin with customer drawings, engineering specifications, worn components, or complete cylinder assemblies requiring reverse engineering. When original documentation is unavailable, existing cylinders can often be evaluated to reproduce the critical dimensions and functional characteristics necessary for proper installation and performance.
Successful hydraulic cylinder design extends beyond selecting bore and stroke dimensions. Rod diameter influences buckling resistance, barrel construction affects pressure capability, mounting geometry determines how loads are transferred into the machine, and seal selection directly impacts leakage control and service life. During custom cylinder fabrication, these features must work together as an integrated assembly while maintaining precise relationships between the barrel, piston, rod, gland, and mounting components.
By combining precision machining with engineering-driven manufacturing, PSI Hydraulics produces custom hydraulic cylinders that satisfy the mechanical and hydraulic demands of each application rather than relying on standardized configurations.

Why Choose PSI
Manufacturing a reliable hydraulic cylinder requires considerably more than matching external dimensions. Pressure capability, sealing performance, rod alignment, and service life all depend on the accuracy of the internal geometry and the relationships between individual components throughout the assembly.
As a hydraulic cylinder manufacturer, PSI Hydraulics approaches every project as a complete engineered system. Our custom cylinder fabrication process emphasizes dimensional accuracy, precision machining, and careful evaluation of critical interfaces that influence performance under load. Whether producing a new cylinder from customer specifications or reverse engineering an obsolete assembly, our objective is to manufacture a cylinder that integrates with the equipment while meeting its mechanical and hydraulic performance requirements.
Frequently Asked Questions
What information is needed to manufacture a custom hydraulic cylinder?
Customer drawings provide the most complete manufacturing information, but existing cylinders, dimensional measurements, engineering specifications, operating pressures, and application details can also be used to develop a custom solution.
Can PSI reverse engineer an obsolete hydraulic cylinder?
Yes. Existing cylinders can often be evaluated to reproduce critical dimensions, mounting geometry, sealing interfaces, and functional characteristics when OEM replacements are no longer available.
Which dimensions are most important during custom cylinder fabrication?
Critical dimensions typically include bore diameter, rod diameter, stroke length, mounting centers, gland and piston interfaces, seal groove geometry, and port locations. Maintaining these relationships is essential for proper fit and hydraulic performance.
How does hydraulic cylinder design affect service life?
Design decisions such as rod diameter, bearing support, sealing arrangement, mounting style, and load alignment directly influence wear rates, side loading, leakage control, and overall cylinder reliability.
Can PSI manufacture a single custom hydraulic cylinder?
Depending on the application, PSI can manufacture prototype cylinders, individual replacement cylinders, or production quantities for OEM and industrial equipment.
What should be included with a quote request?
Providing drawings, photographs, operating specifications, pressure requirements, bore and stroke dimensions, mounting details, or an existing cylinder allows the project to be evaluated more efficiently.
