The RD20013 from Power Team is a heavy-duty 200-ton capacity double-acting push/pull hydraulic cylinder, featuring a 13.13 in (13-1/8 in ) stroke, a retracted height of 22.5 in and extended height of 35.625 in. It delivers up to approximately 206 tons of push at 10,000 psi and about 113 tons of pull under full pressure.
Built for harsh industrial applications like bridge lifting, shipyard work, and utility/mining repair, it features chrome-plated piston rod resistant to corrosion, aluminum-bronze overlay bearings for extended service life, a removable load cap with high-capacity threaded pull capability, dual 3/8 in NPTF female half-couplers, and a built-in safety relief valve for retract over-pressure protection.
Push & pull capability: Because it’s double-acting, the RD20013 can apply force in both extension and retraction, which is useful in applications requiring controlled push and pull.
High tonnage with long stroke: Combines significant capacity 13 1/8″ stroke, making it suitable for heavy lifting, jacking, or positioning tasks where both reach and force are needed.
Durability & service life: The use of aluminum bronze bearings, chrome rod, and heavy load caps contributes to extended life under cyclic heavy loads.
Safety features: Internal relief valve helps prevent damage or risk in case the retract line is blocked or misused.
Pull thread & load cap flexibility: The removable load cap exposes internal threads so the same cylinder can be used to pull (retract) with full rated force.
Robust design for industrial service: Designed for heavy applications such as bridge lifting, shipyard operations, utility / mining maintenance.
Internal safety relief: Built-in relief valve protects the retract circuit from overpressure if the retract port is blocked or restricted.
Mounting / threads: The cylinder includes mounting holes, collar threads, and the load cap’s threaded section to allow secure installation or pulling operations.
Capacity (Push): 200 ton rated
Capacity (Pull / Retract): ~113.1 ton
Stroke: 13.13 in
Retracted height: 22.50 in
Extended height: 35.625 in
Effective area (push side): 41.28 in²
Effective area (pull side): 22.62 in²

Load cap / Pull capability: The load cap is removable to expose internal piston-rod threads rated for full tonnage for pulling applications.
Construction / Materials:
• Aluminum-bronze overlay bearings for durability under heavy loads
• Chrome-plated piston rod to resist corrosion
• Heavy duty load cap with grooved ring pattern to help reduce slippage
Size & weight: At 356 lb and over 22.5 in retracted height, it’s not compact — needs sufficient clearance and strong support structure.
Hydraulic system demands: To fully utilize the push and pull capacities, the pump and hoses must support sufficient flow and 10,000 psi pressure.
Alignment & side loads: As with any high-tonnage cylinder, misalignment or off-centre loading can shorten life or damage the unit.
Maintenance of safety features: The relief valve is internal and should never be blocked or tampered with; if leakage is detected from the relief, service is required.
Oil volume & fluid handling: Large displacements mean more hydraulic fluid movement—slow response or lag may occur if pump flow is insufficient.
Typical ApplicationsHeavy machinery lifting and re-positioning (e.g. bridge decks, structural segments).
Tasks where both pushing and pulling cycles are required (e.g. pulling rods or ejecting components).
Shipbuilding, port / marine operations, utility and mining equipment maintenance.
Structural and repair jobs where combined reach and force are needed over a moderate stroke.
Center hole cylinders operate at a maximum working pressure of 10,000 PSI and are designed for use with compatible high-pressure hydraulic systems.
