The choice of materials in manufacturing oil seals is crucial. Typically, these seals are made from elastomers, including rubber compounds that provide excellent flexibility and resilience while maintaining a strong barrier against contaminants. This makes them adept at handling the challenges presented by various operating environments, including high temperatures and pressure fluctuations.

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.

Oil seal manufacturers are responsible for designing and producing seals that meet the specific requirements of various applications. Their expertise lies in selecting the right materials, such as rubber, elastomers, or thermoplastics, that can withstand extreme temperatures, pressures, and chemical exposures. Quality is a major focus for these manufacturers, as a poorly designed or manufactured oil seal can lead to catastrophic failures.

1. Dimensions The numbers can indicate the dimensions of the seal. For instance, the first number may denote the inner diameter, the second, the outer diameter, and the third could refer to the width or height of the seal. These dimensions are critical for ensuring that the seal fits perfectly within the intended assembly, thereby maximizing effectiveness.
