Custom Double-Rod Hydraulic Cylinder
URL Slug: custom-double-rod-hydraulic-cylinder-balanced-force-speed
Product Summary
Our custom double-rod hydraulic cylinders, available in the APEX-CDRC series, are engineered for applications demanding equal force and speed in both directions. The through-rod design provides a balanced effective area, ensuring identical push and pull forces when rod diameters are equal. This makes them ideal for reciprocating motions and synchronized systems.
Key Selling Points
- Equal Effective Areas: When both piston rods have identical diameters, the cylinder provides equal effective areas on both sides, resulting in balanced force and speed in both directions.
- Balanced Push and Pull: The equal-area design delivers approximately equal push and pull forces, simplifying hydraulic circuit design and improving synchronization.
- Through-Rod Construction: The rod extends through the entire cylinder, improving piston alignment and resistance to side loading for enhanced stability.
- Customizable Configurations: Choose from centered or offset stroke, various mounting styles (center trunnion, foot, flange), and rod-end interfaces to fit your machine.
- Application-Specific Seals: Standard seals for -20°C to +80°C, with extended ranges from -40°C to +120°C using appropriate seal materials and treatments.

FAQ
What does double-rod (through-rod) mean?
A double-rod cylinder has a piston rod extending from both ends, providing equal areas on both sides when rod diameters are same, leading to equal force and speed in both directions.
Can I get different rod diameters on each side?
Yes, unequal double-rod configurations are available for specific force or speed requirements.
What mounting options are available?
We offer center trunnion, foot, flange, side lug, and custom mounting to suit your equipment.
What is the maximum pressure rating?
Working pressure is 100-250 bar, with max design pressure up to 350 bar for special designs.
Can the cylinder operate in low temperatures?
Standard is -20°C to +80°C; with special seals, operation is possible from -40°C to +120°C.
Do you provide position feedback?
Yes, we can integrate proximity switches, magnetic sensors, or linear transducers.
What testing is performed?
Each cylinder undergoes dimensional inspection, pressure testing, leakage testing, and full-stroke functional testing.
