Product Description

Product Description

Engineering Double Acting Single Piston Rod Hydraulic Cylinders for Excavator Mining Machinery

DGRHSG*01-E series are all double acting single piston rod hydraulic cylinders, which are actuators in the hydraulic system that move in a straight line. It has simple structure, reliable operation, with other characteristics like convenient assembly and disassembly, easy maintenance, and diverse connection methods.

The installation method often adopts earring type. According to the connection method between the cylinder head and the cylinder block, it can be divided into three types: external thread connection, internal key connection, and flange connection.

The engineering hydraulic cylinder mainly uses hydraulic systems for engineering machinery cities, heavy machinery piles, lifting and transportation machine, and mining machinery combs.

Note:
1. Speed ratio ϕ refers to the ratio of the effective area of the piston to the effective area of the piston rod cavity.
2. The rod diameter size in the speed ratio of 1.46 is the preferred series.
3.In principle, the maximum stroke: ϕ=1.33, S=8D; ϕ=1.46, S=10D; ϕ=2, S=12D.
4. When the user's required S exceeds the maximum stroke specified in the table, it should be resolved through mutual consultation.
5. The minimum stroke for non hinged shaft and middle flange connections shall be as shown in the table above.
6. 1MPa is approximately equal to 10Kgf/cm².
