Hydraulic cylinders maintenance : 5,  before disassembling the hydraulic cylinders, the system should be unloaded, the circuit pressure should be zero, the oil source should be cut off, and the oil port should be blocked after loosening the oil port piping to ensure safety. 6, when the hydraulic cylinders leak and other faults need to be disassembled and repaired, the piston rod should be moved to the bottom of the cylinder first, and it is strictly forbidden to hit with hard objects during disassembly, so as to avoid the sudden drop of the piston rod and cause damage. 7, inactive or idle hydraulic cylinders for a long time should be turned on the operated regularly, so that all hydraulic cylinder components can be completely lubricated, so as to avoid rust on the working surface and affect the normal application in the future.

we will try our best to develop new hydraulic  cylinders . For example A hydraulic cylinder. A cylinder are commonly used in heavy duty construction equipment. A cylinder features a 3600 psi pressure rating. It will be functional tested and pressurized to ensure performance reliability. Other requirements are as below : 1) induction hardened, hard chrome plated piston rod 2) spherical bearing 3) double acting applications 4) tube:  presition honed steel

Two methods to keep cylinder use for a long time Hydraulic cylinder is the heart of hydraulic system, so it is very important to know the ways to keep your cylinder use for a long time. 1) Anti rust. cylinder rod will be extent out during working process. So cylinder rod should be anti rust to prevent the oxidation. That is why cylinder rod will be chrome plating during production. 2) Change hydraulic oil from time to time. Beause the frequent use of hydraulic cylinder, it is inevitable that something will enter into the hydraulic oil. This contaminant will lead to friction inside cylinder tube. Besides,cylinder oil also has time limited. So hydraulic oil should be changed from time to time to safeguard the hydraulic cylinder.
