Built to Perform, Backed by Full-Service Manufacturing

Specialized custom hydraulic cylinders are engineered solutions designed to meet unique performance, environmental, and operational demands that standard cylinders simply can’t accommodate. These cylinders are built to match exact specifications—whether that means extreme pressures, unusual mounting configurations, harsh environments, oversized dimensions, or highly precise motion control. Industries such as construction, marine, mining, rail, defense, and energy often rely on custom cylinders when equipment must perform in conditions where reliability, safety, and durability are non-negotiable.

At RHK Hydraulic Cylinder Services Inc., we specialize in designing and manufacturing custom hydraulic cylinders tailored to your specific application. From one-off prototypes to full production runs, we can engineer cylinders in virtually any bore size, stroke length, material grade, or configuration. Our team works closely with you to understand the forces, duty cycles, and environmental factors involved, ensuring every component is built to perform flawlessly.
