- 1. Face-Type Metal-to-Oil Seal This type of seal consists of two metal rings that are pressed together to create a seal. The rings have matching grooves that hold the sealing element in place. Face-type seals are commonly used in applications where the shaft has a small diameter.
However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
- Furthermore, the oil seal 45 65 10 is designed to provide long-lasting performance, reducing the need for frequent replacements and maintenance. This not only helps in improving the efficiency of machinery but also decreases downtime and overall operating costs. With its superior sealing capabilities, this oil seal ensures smooth operation and extended lifespan of equipment.

18 - The quality and condition of diesel glow plugs significantly impact the overall efficiency of the engine
diesel spark plugs. High-quality spark plugs, such as those from renowned brands, ensure a more consistent ignition, smoother engine operation, and better fuel economy. They are usually made from durable materials like platinum, iridium, or ceramic, providing longevity and resistance to extreme temperatures.

Offering a much more superior temperature resistance, polyacrylate seals are perfect for applications such as high surface speed oil. Benefits include:
Clean all dirt and oil from the housing, and set the new seal in place with its open (spring) side towards the engine.

(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.

Fundamental things and its importance
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
