If you are looking for the highest temperature resistant oil seals, Perfluoelastomer can go up to 600°F. If you are more concerned for low temperature, Chloroprene can go all the way down to 40°F, which is why it is used most commonly for refrigeration. And if FDA applications or medical devices are your primary concern, Butyl , the all petroleum compound, will be your best choice. As you can see, when choosing the right material to work with, you must analyze several other key components to help choose the right one.
- Despite their seemingly small size, 35x50x8 oil seals have a significant impact on the overall performance and longevity of equipment. Their selection, installation, and maintenance must be done with precision to ensure optimal functionality. Regular inspection for signs of wear, damage, or leaks is crucial to prevent potential breakdowns and costly repairs.
Shaft hardness should be at least 30 HRC. In usage conditions where wear can occur easily because of dust or contaminated oil, hardness should be 50-60 HRC.

Silicone (VMQ) Oil Seals
Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.

Shaft Speed
Another common cause of black spark plugs is engine oil leakage. If oil is leaking into the combustion chamber, it can cause the spark plugs to become fouled with a black, sooty residue. This can lead to misfires and engine hesitation, as well as increased fuel consumption. It is important to address any oil leaks promptly and replace the spark plugs if necessary.
(4) The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a W-shaped oil seal can be used.
