What are the differences between dustproof sealing ring and oil seal? Which equipment should be dustproof? In daily life, machinery and equipment, engineering machinery and equipment, automobiles and so on all need to achieve dust-proof sealing effect. Generally, sealing parts manufacturers will be used for the sealing ring or sealing ring of rubber sealing material damaged by the invasion of dust and dirt glume of homeowners. However, the oil seal is also a kind of seal, and what is the actual difference between the dust seal ring. How do we tell the difference?

The difference between dustproof seal and oil seal:

First dustproof seal is generally used for oil pressure machinery, air pressure and hydraulic machinery equipment, and is composed of rubber sealing ring specifications and materials. In special cases, the outside of the cylinder and piston rod in cold work is frozen, and the chemical industry department also uses metal to prevent the sticking on the piston rod. If the hydraulic equipment infiltrates dust, it will not only wear the lip seal structure, but also lead to wear of the guide sleeve and piston rod. Secondly, impurities into the hydraulic medium, will also affect the function of the operating valve and pump. In the worst case, they could be damaged. Dustproof seal (sealing ring) can get rid of the dust and debris on the surface of the piston rod, but damage the oil film on the live cold rod, which also has a certain role in the lubrication of the rubber sealing ring.

Two, oil seal is divided into skeleton and skeleton oil seal seals. Oil seals are often used in mechanical bearings, especially rolling bearings. The function of oil seal is to isolate the oil chamber from the outside, seal the oil inside and seal the dust outside. Oil seal light weight, less consumables, good sealing performance, long service life, vibration of the machine and eccentric spindle have a certain adaptability. Oil seals can be used as dustproof seals, but in serious dust or in order to protect other seals, special dustproof seals are often used.
