5000mm High Stroke Hydraulic Jack Hydraulic Cylinder for RV
1. Cylinder Barrel
Hydraulic Equipment includes Engineering Hydraulic Cylinder, Hydraulic Cylinder for metallurgical equipment, Hydraulic Cylinder For Industry and Thin Hydraulic Cylinder, etc. The commonly used materials of DGR-MOB Series hydraulic cylinder are seamless steel pipes of 20#, 35#, and 45#, which have been honed or rolled to meet the European roughness requirements of less than 0.4um. Low pressure oil cylinders can use 20# steel pipes, while high pressure oil cylinders can use 45# steel pipes.
2. Piston Rod
There are two types of piston rods: solid rod and hollow rod. One end of the hollow piston rod should have a vent hole for welding and heat treatment.
The material of the plug rod is 35# and 45# steel, and the material of the hollow piston rod is 35# and 45# seamless steel pipe.
After rough machining, the piston rod is quenched and tempered to a hardness of 229-285HB. If necessary, it is then subjected to high-frequency quenching to achieve a hardness of 45-55HRC.
3. Cylinder Head
Castings for low pressure, HT300 gray iron for medium and low pressure, and 35# and 45# steel for medium and high pressure.
When the cylinder head itself is the guide sleeve of the piston rod, it is best to choose cast iron for the cylinder head. At the same time, brass, bronze. or other wear-resistant materials should be melted onto the quide surface. If a structure with a guide sleeve pressed into the cylinder head is used, the guide sleeve should be wear-resistant cast iron, bronze, or brass.
4. Piston
Commonly used materials are wear-resistant cast iron, gray cast iron (HT300, HT350), steel, and aluminum alloy. The coaxiality tolerance value of the piston and piston rod in the structural diagram should be 0.03mm.
