Furthermore, the handbook delves into the regulations governing plastic and polymer additives, highlighting the significance of safety assessments and compliance with environmental standards. As public awareness of plastic pollution and its environmental impact grows, regulatory bodies have imposed stricter guidelines for the use and disposal of plastic materials. By understanding the chemical analysis of plastic additives, manufacturers can ensure their products meet these regulatory requirements while also maintaining performance quality.

It is possible to get custom-made seals manufactured at reasonable rates from good-quality manufacturers if the readymade seal specification doesn’t meet the requirement.
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
Aspects to consider when selecting oil seals

Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.

When it comes to choosing the right oil seal for a particular application, there are several factors to consider. One of the key aspects is the material used in the construction of the seal. Different materials offer varying levels of resistance to heat, chemicals, and wear, so it is essential to select a seal that can withstand the specific conditions it will be exposed to.

BENEFITS OF OIL SEALS

wheel oil seal. Signs of a faulty wheel oil seal include oil leakage from the wheel hub, unusual noise coming from the wheel assembly, and excessive play or wobbling of the wheel. If any of these symptoms are noticed, it is important to have the wheel oil seals replaced immediately to prevent further damage to the wheel bearings.
