Skeleton oil seal
145*175*13/14
The function of the skeleton oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to allow the leakage of lubricating oil. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the structure, it can be divided into single lip skeleton oil seal and double lip skeleton oil seal. The auxiliary lip of the double-lip skeleton oil seal plays a dust-proof role to prevent external dust and impurities from entering the machine.
1. The oil seal has a simple structure and is easy to manufacture. Simple oil seals can be molded at one time, and even the most complex oil seals have no complicated manufacturing process. Metal skeleton oil seals can also form the required oil seals from metal and rubber only through stamping, gluing, inlaying, molding and other processes.
2. The oil seal is light in weight and less consumables. Each oil seal is a combination of thin-walled metal parts and rubber parts, and its material consumption is very low, so the weight of each oil seal is very light.
3. The installation position of the oil seal is small, the axial dimension is small, it is easy to process, and the machine is compact.

material | Low TEMP. |
High TEMP. |
Performance | ||||
NBR | -40 | 120 | Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters |
||||
HNBR | -25 | 140 | HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties. |
||||
ACM | -25 | 150 | It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance. |
||||
EPDM | -40 | 125 | Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler. |
||||
VMQ | -60 | 125 | The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance. |
||||
FKM | -20 | 250 | Fluoroelastomers have a high degree of chemical stability and are currently the best media resistance of any elastomer. Type 26 fluoroelastomer resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on |
