- In the intricate world of automotive engineering, where every component plays a pivotal role in the smooth operation of a vehicle, the 14mm spark plug may seem like a diminutive piece amidst the vast machinery. However, this unassuming part carries significant weight in terms of performance and efficiency.
The shaft on which the oil seal is mounted has to be ground to a rough surface finish. The shaft also should be hardened to prevent grooves forming on the shaft when the pressure is exerted by the spring on the seal. The area where the seal is fitted also has to be ground to prevent grooves that tend to wear out the lip of the oil seal faster than normal.
silicone rubber is better than silica gel for fuel oil and mineral oil, but it is inferior to silica gel in
precision, high temperature resistance, high wear resistance, harsh conditions, military products use more.
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.
