The single-acting lightweight cylinder (spring return) "PRH Series" is an ideal single-acting pull jack for tensioning and alignment. It comes standard with a special heat-resistant bellows to protect the plunger, and the jack returns via a spring after being stroked. 【Features】 ◯ The cylinder base is made of aluminum, making it about half the weight compared to steel. ○ A female coupler (CR-400) and dust cap are standard equipment. → The male coupler that connects to the PRH type female coupler is CH-604.

It was developed at the strong request of operators using hydraulic cylinders in welding operations. It improves work efficiency and extends cylinder lifespan, thereby increasing cost efficiency. For more details, please contact us or refer to the catalog.

Single-acting hydraulic pull cylinder

Lightweight manual pump set with cylinder and 1.8m rubber hose (with coupler) for easy portability.

We have added a lineup of aluminum single-acting strong cylinders with reinforced saddles and base plates, designed for tasks that require maximum cylinder capacity and have a relatively high frequency of use.

Portable single-action hydraulic cylinder with handle.

● Single-acting general-purpose cylinder ● Single-acting aluminum cylinder ● Single-acting flat/low-profile cylinder ● Single-acting pull cylinder ● Single-acting jack for heavy lifting ● Double-acting jack for heavy lifting ● Single-acting jack for heavy lifting (with safety nut)

Compared to a steel cylinder, it weighs half as much and is light enough to be carried by hand.

The "2-stage telescopic cylinder (load return)" is a hydraulic cylinder that incorporates two plungers. Compared to a single plunger cylinder, it allows for a longer stroke in a limited space. We also offer a "3-stage telescopic cylinder (load return)" that incorporates three plungers. 【Features】 <2-stage telescopic cylinder (load return)> ■ Improved wear resistance on both inner and outer surfaces due to nitro carburizing surface treatment ■ Prevents corrosion and damage to the inner surface of the cylinder ■ Ensures product lifespan and safety in harsh environments ■ Can withstand eccentric loads up to 3% of the maximum capacity of the cylinder ■ Can be used at maximum load capacity during the first stage stroke *For more details, please refer to the PDF document or feel free to contact us.

The "RA Series" is a single-acting/double-acting aluminum cylinder that weighs about 50-60% less compared to steel cylinders, making it easy to transport and install. With bearings synthesized from new materials, a floating state is formed on the sliding surface of the cylinder, allowing it to withstand lateral loads of up to 10% of its capacity, while also reducing cylinder wear. Additionally, we offer the double-acting aluminum center hole cylinder (hydraulic return) "RARH Series," which is approximately 40% lighter than steel center hole cylinders. 【Features】 ■ Weighs about 50-60% less compared to steel cylinders ■ Easy to transport and install ■ Can withstand lateral loads of up to 10% of its capacity, while reducing cylinder wear ■ The main material, aluminum alloy steel, can be safely used even in environments prone to rust *For more details, please refer to the PDF document or feel free to contact us.

The "RC Series" is a single-acting cylinder (spring return) that incorporates a double bearing (GR2) structure into the RC DUO cylinder. The return mechanism of the cylinder uses a reinforced spring, achieving both powerful tension and remarkable durability. The capacities range from 45kN to 100kN, 142kN, 233kN, 293kN/500kN, and 718kN/933kN. 【Features】 ■ The hydraulic seal is surrounded by bearings at both ends, allowing for effective distribution of eccentric loads. ■ By reducing the burden on the hydraulic seal, the durability is significantly improved compared to conventional products. ■ Prevents galling on the inner surface of the cylinder and early bearing damage caused by eccentric and dynamic loads. *For more details, please refer to the PDF document or feel free to contact us.
