- The primary function of a mechanical oil seal is to create a barrier between the rotating shaft and the stationary housing, preventing the escape of oil and other lubricants. This helps to maintain proper lubrication levels within the equipment, reducing friction and wear on moving parts. Additionally, oil seals help to prevent contamination of the lubricant by dirt, dust, and other contaminants that can lead to premature wear and equipment failure.

u shaped rubber gasket. The U shape of the gasket creates a compression seal when it is installed, ensuring that no air or liquid can escape from the sealed area. This tight seal helps to prevent leaks, reduce energy loss, and protect sensitive equipment from environmental contaminants.
Fundamental things and its importance
Notes
*1 ASTM: American Society for Testing and Materials
*2 For more details on fluid compatibility, please see the following:

-20 °C to + 130 °C
The temperature range of the mechanism in which the seal is installed must not exceed the temperature range of the seal elastomer.
Unscrew the pulley bolt anticlockwise with a socket and bar. Start it turning with a sharp blow on the bar.
Box: If a BX appears at the end of the part number, that oil seal will be in a box.
