It can be used as a guide ring for the piston rod to support and guide the piston rod. It has excellent vibration damping performance and is simple and safe to install. It is made of metal and plastic materials. It can prevent work stagnation and violent vibration. The embossed structure facilitates the formation of lubricating micro-pits and improves lubrication. At the same time, the seal prevents the intrusion of tiny foreign objects and protects the sealing system.

According to the material, DMS Seals’s products are divided into several categories, and oil seals are one of them.

Wiper seals are utilized to remove contaminants like moisture, soil, and dust. Some wipers or even scrapers possess a secondary lip utilized to catch any oil which might have bypassed the major seal. The secondary lip can also get rid of any bonded contaminate in the pole surface. These kinds of wipers are usually called double-edged wipers. Metallic scrapers could be used for sub zero temperature software and especially arduous software where foreign substances can deposit the pole.

Gasket sealing mechanism: The function of the gasket is caused by the blocking effect on the internal medium formed by the contact pressure of the sealing material on the joint surface and the elastic restoring force to the external tightening force. Classification and structure of gaskets: Gaskets are divided into three categories: non-metallic gaskets, non-metallic and metal combined gaskets and metal gaskets. The common materials are rubber, leather, asbestos board, cork, PTFE, tinplate, steel, aluminum, copper and stainless steel.

Construction machinery sealing system requirements: High and low temperature resistance Because of continuous work for a long time, if it is outdoors in summer, the hydraulic oil temperature of the machine may exceed 100°C, which requires the seal to be resistant to high temperature. If it is outdoors in winter, the temperature may be around -40°C when it is just turned on, and the seals are required to be resistant to low temperatures. Therefore, the sealing system is required to withstand a wide temperature range. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small.
