70x90x10 oil seal

Understanding the 70x90x10 Oil Seal Specifications and Applications

Oil seals, essential components in mechanical systems, play a crucial role in preventing the leakage of oils and lubricants while also protecting the internal parts of machinery from dust and contaminants. One such oil seal type is the 70x90x10 oil seal, characterized by its specific dimensions and design features. This article delves into the significance, applications, and benefits of this particular oil seal size, helping you understand its importance in various industries.

What Does 70x90x10 Mean?

The dimensions of an oil seal are typically noted in millimeters, where 70x90x10 refers to the inner diameter, outer diameter, and width of the seal, respectively. In this case

- Inner Diameter (ID) 70 mm - Outer Diameter (OD) 90 mm - Width (W) 10 mm

The notations may also include additional identifiers, such as the percentage ( ) that often relates to the material composition or specific design features of the seal. Although the exact meaning of this additional portion may vary, it often designates characteristics like the hardness or type of sealing lip used.

Construction and Materials

Oil seals, including the 70x90x10 type, are typically made from a variety of materials depending on their intended application. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone rubber. NBR is often favored for its excellent resistance to petroleum-based oils and general durability. On the other hand, FKM provides superior temperature resistance and is suitable for aggressive fluids.

The construction involves two primary components the sealing lip and the outer casing. The sealing lip creates a flexible barrier that adapts to the shaft's surface, while the outer casing ensures a secure fit within the housing. The design must account for various factors, including pressure differences, shaft speed, and temperature fluctuations.
