Experience unmatched power and precision with our high-performance Cissoko Hydraulics Welded Double Acting Hydraulic Cylinder with a 3-inch bore and 6-inch stroke with clevis ends and 3500 PSI. This cylinder is a best option for heavy-duty hydraulics. Perfect fit to automotive hydraulic applications (vehicle lifts, dump trucks, towing and recovery), construction equipment (loaders, bulldozers), agricultural machinery (tractors, combine harvesters, sprayers), forestry (tree harvesters, skidders), and mining equipment (drilling rigs, haul trucks).
High-pressure durability : Rated operating pressure up to 3000 PSI , made with high-strength microalloyed steel tubing and cast steel lug base, designed specifically for heavy-duty industrial and agricultural machinery.
Excellent corrosion resistance and lifespan : The piston rod is precision ground, polished and hard chrome plated , which can effectively reduce frictional resistance, prevent scratches and extend the life of the seals.
Easy-to-maintain design : Equipped with a threaded screw-in cylinder head (Gland Cap) , it can be easily disassembled without special clamping tools when the seal needs to be replaced or maintenance is required.
Long stroke load capacity : While meeting the requirements of 18" long stroke operation, it combines heavy-duty cast steel lugs to have excellent lateral load resistance and high cost performance.

Applications
Primary Vehicle Applications
Standard Dump Trucks (Class 7 & Class 8): Widely used on 10-wheelers, tri-axle, and quad-axle dump trucks with body lengths ranging from 14 to 18 feet .
Dump Trailers & End Dumps: Installed on medium-sized end dump semi-trailers or heavy-duty pull trailers requiring an aggressive tilt angle to shed stubborn
Pup Trailers: Commonly used on independent dump pup trailers towered behind a standard dump truck to maximize total hauling capacity.
Construction & Aggregates: Lifting heavy loads of gravel, crushed stone, sand, and asphalt on rugged construction sites.
Demolition & Waste Management: Tipping large-volume truck bodies carrying concrete debris, scrap metal, and heavy municipal waste .
Mining & Earthmoving: Operating on site-specific support vehicles hauling heavy soil, overburden, and mineral ores .
Agriculture: Used on specialized agricultural bulk trailers for high-volume dumping of grain, silage, and fertilizers .
3 Bore × 6 Stroke Clevis Hydraulic Cylinders are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Physical space requirements: Although the piston rod can only move 6 inches, there must be enough space inside the cylinder to accommodate the heavy-duty piston (usually thicker) corresponding to the 3-inch cylinder diameter , the front guide cap, the internal stop ring, and the extremely thick 1-inch lug mounts at both ends.
Standard dimensions: When fully retracted, the center distance (installation distance) between the pin holes at both ends is 16.25 inches ; when fully extended, it is 22.25 inches . Please ensure there is sufficient space to accommodate the equipment before ordering.
Thrust (extended): It can generate a terrifying theoretical thrust of up to 21,205 pounds (about 9.62 tons) at 3,000 PSI .
Pull force (retraction): Due to the 1.5-inch thick piston rod occupying part of the cylinder volume, the pull force will be reduced, but it can still provide about 15,904 pounds (about 7.21 tons) of pull force at 3,000 PSI.
Preventing high-pressure impact deformation: A 3-inch cylinder can generate a massive impact or thrust of nearly 10 tons during operation. If the piston rod is too thin, even with a short stroke of only 6 inches, it is highly susceptible to being bent or shattered by the enormous reaction force when pushing heavy objects or encountering sudden lateral impacts (such as excavators or dump trucks with gravel in their beds). A 1.5-inch thick rod ensures extremely high longitudinal load-bearing safety.
3,000 PSI level: Mostly adopt standard tie-rod structure or ordinary welded structure, meeting the needs of most standard agricultural machinery or medium-sized industrial equipment.
3,500 PSI level: Brands such as Magister use high-strength cold-drawn steel tubular cylinders, steel threaded guide caps, and a five-piece combination sealing ring. This structure offers better resistance to explosions and leaks when facing extreme high pressure or instantaneous spike pressure generated by hydraulic systems.
Oil port selection: The market mainly offers modern leak-proof SAE 8 (ORB) threaded interfaces and old-fashioned high-flow 1/2" NPT threaded interfaces.
Vibration Protection During Operation: Because the stroke is only 6 inches, if the hydraulic pump flow rate is high (e.g., exceeding 8 GPM), the cylinder may suddenly reach its full length or retract to the bottom in less than 1 second. This rapid and violent bottoming out can cause severe mechanical impact and hydraulic vibration. It is recommended to operate the hydraulic valves gently, or to install a throttle valve (flow control valve) in the pipeline to control the smooth extension of the cylinder.
