Piston Rod Seal NBR

There are many kinds of Piston Sealing rings, such as piston dustproof Sealing ring, piston rod main Seal, Buffer Ring, antifouling ring, anti-wear Sealing ring, etc. The oil cylinder is composed of a cylinder body, a piston, a piston rod, a cylinder head and a sealing ring. The piston sealing ring refers to the seal between the cylinder body and the piston. Poor sealing will affect the performance of the oil cylinder. Piston rod sealing ring refers to the seal between the piston rod and the cylinder head. Poor sealing will lead to oil leakage. Generally, the sealing groove is opened on the hole and on the shaft.

The sealing structure and sealing ring for the piston rod are the key components in the reciprocating actuator. It is not only related to leakage problems, but also affects the performance and life of the entire machinery and equipment. In the reciprocating motion actuator, the piston rod mainly bears a certain axial force, and reciprocates at a certain speed to perform external work. With the development of science, technology and industry, the requirements for reciprocating motion are getting higher and higher, especially in the case of high pressure and high speed motion, the problem of sealing structure and sealing ring for piston rod is particularly important.
