The hydraulic cylinder cylinder is the main body of the honing pipe. The inner hole is generally manufactured by precision machining such as boring, reaming, rolling or honing, so that the piston and its seals and supports can smoothly slide and reduce wear; hydraulic cylinder The cylinder is subjected to a large hydraulic pressure and, therefore, should have sufficient strength and rigidity.
The end caps form a closed oil chamber with the cylinder barrel at both ends of the cylinder tube. Therefore, the end cap and its connecting member should have sufficient strength. The design must consider both the strength and the structural form with better craftsmanship. The guide sleeve guides and supports the piston or the plunger. Some hydraulic cylinders do not have a guide sleeve and are directly guided by the end cover hole. This structure is simple, but the end cover needs to be replaced after wear.
