In addition to their durability, metal oil seals also offer excellent sealing capabilities, helping to prevent the escape of oil and other fluids from equipment. This is crucial for maintaining the proper lubrication of moving parts and ensuring that machinery operates efficiently. By creating a tight seal between mating surfaces, metal oil seals help to reduce friction and wear, extending the lifespan of components and reducing the need for maintenance.

The design of a grating usually involves considerations such as the material, the number of grooves per millimeter, the depth of the grooves, and the angle of incidence. In the case of 19w2% grating, the choice of material is critical. Common materials used for fabricating gratings include glass, quartz, and specialized polymers, each chosen based on the specific application. For ultraviolet applications, for instance, materials that absorb less in the UV range are preferred.
