Installation and maintenance of fiberglass trough covers are relatively straightforward
- The elasticity and flexibility of silicone gaskets enable them to conform to irregular surfaces, creating a tight seal that prevents leaks and protects sensitive components
J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
Double Lips - In addition, the 49055s spark plug is designed to provide better fuel efficiency and improved engine performance
49055s spark plug. By delivering a consistent spark and igniting the air-fuel mixture efficiently, the 49055s spark plug helps the engine run smoothly and efficiently. This leads to better fuel economy and overall performance.
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
What material are oil seals made from?

Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure


When selecting industrial oil seals, it is essential to prioritize quality, durability, and compatibility with specific machinery and equipment. High-quality oil seals are designed to withstand the demanding conditions of industrial operation, providing reliable sealing solutions that contribute to the overall performance and safety of the machinery. Choosing reputable suppliers and manufacturers known for producing high-quality industrial oil seals is crucial to ensure the reliability and longevity of these critical components.
