retractable cylinder are widely used in India，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed retractable cylinder for customers from India.

Introduction to retractable cylinder:

retractable cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the retractable cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

In use, the retractable cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the retractable cylinder.

After chrome plating of the piston rod of the retractable cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The body of the retractable cylinder on the processing process requirements: the body of the retractable cylinder is an important and essential part of the retractable cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the retractable cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about retractable cylinder:

Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.
