Understanding the 35x47x7 Oil Seal Specifications and Applications

Oil seals play a crucial role in various machinery and automotive applications. Among these, the 35x47x7 oil seal has gained popularity due to its effective sealing properties and broad applicability. This article delves into the specifications, functions, materials, and common applications of the 35x47x7 oil seal.

Specifications of the 35x47x7 Oil Seal

The designation 35x47x7 refers to the dimensions of the oil seal a 35 mm outer diameter, a 47 mm inner diameter, and a 7 mm thickness. The number system is standard in the industry, aiding engineers and technicians in identifying the right seal for specific applications quickly. The design typically features a rubber sealing lip that fits snugly against the rotating shaft, preventing the leakage of lubricants while keeping out dirt, dust, and moisture.

Functions of the Oil Seal

The primary function of an oil seal is to contain lubricants within machinery, ensuring that the components operate smoothly without friction-induced damage. It acts as a barrier, maintaining the oil or grease within the system while preventing contaminants from entering. This is essential for the longevity and reliability of moving parts, particularly in environments where dust and debris are prevalent.

Another critical function is to prevent the leakage of hydraulic fluids in hydraulic systems. Hydraulic systems are often under high pressure, and any failures in sealing could lead to significant operational inefficiencies and potential damage to machinery.
