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
Furthermore, the 30-50-10 oil seal is designed to withstand prolonged use and harsh operating conditions. This makes it suitable for a wide range of applications, including automotive, industrial, and agricultural machinery.
