In line with global environmental standards, spark plug manufacturers in China are increasingly focusing on sustainable practices and eco-friendly materials. Compliance with environmental regulations and the adoption of green manufacturing processes are becoming integral to the production of spark plugs. Customers seeking spark plugs and wires can inquire about the environmental policies and certifications of suppliers to align with their sustainability goals.
Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.
Nitrile rubber offers good durability for general use, while the flexibility of the spring behind the sealing lip keeps the oil seal firmly in place against the moving part.
This is almost similar to that of ‘A’ type seal. But this has the metal case placed outside. When the housing is rough, temperature is high and working conditions are severe, this type is preferred
Although it does have a higher tensile strength and longer wear times than other materials, it is recommended to be used in dry-running applications sparingly or intermittently.
The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.
Does it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
