Description
The support ring of the hydraulic cylinder seal is installed on the inside of the end cover of the hydraulic cylinder.
* To support the piston rod; preventing the piston rod from vertical pressure to bring uneven sealing pressure caused by the rod seal and the poor sealing effect. Short life and other effects.
* Second, the guide ring of the hydraulic cylinder seal ring
The back up ring of the hydraulic cylinder seal is installed on the piston, and its main function is to guide the piston to perform linear motion, to prevent the piston from deviating due to uneven force, causing internal leakage and reducing the life of the seal.
* The service life of the back up ring and the support ring directly affects the use effect and life of the piston seal and the piston rod seal, so the requirements for the back up ring are also high, such as low friction coefficient, high hardness, long service life, etc. .
* There are many forms of guide belts and support rings, and they are also used in combination with the main seal.
