Features

O-Ring, JISB2401 P Series (for Fixing/Dynamic):Related images

An annular packing with an O-shaped cross section that seals in fluids and dust.

An O-ring is an annular packing with an O-shaped (circular) cross section that is fitted in a groove and compressed appropriately to prevent the leakage of a wide variety of fluids such as oil, water, air, and gas. By making full use of synthetic rubber suitable for a variety of purposes, it is possible to withstand long-term use and use under harsh conditions.

Technical Information

O-ring sealing principle

The sealing principle of the O-ring is that the compressed O-ring maintains the repulsive force to seal.

O-ring JISB2401 P series (fixing/dynamic), O-ring sealing principle
 

Properties required for O-ring materials

Since O-rings exert their sealing force by the stress generated by crushing, it is fundamentally required that they have an appropriate amount of stress within a range that does not cause abnormal deformation.
This basic property must not be lost during use. Synthetic rubber is one of the best material with these properties.
However, it is difficult to cover all of these properties with a single material, so it is necessary to use different materials according to each application.

Cautions and Prohibitions

Precautions for storage and storage period

Please note the following points when storing O-rings.

  • Do not open the package unnecessarily. Contaminant or dust may stick to it, or it may be scratched.
  • When storing a product that has been opened, be careful not to let contaminant or dust adhere to it or mix it in, or scratch it.
  • Store it in a place away from direct sunlight with low humidity. Ultraviolet ray and moisture can accelerate the deterioration and dimensional changes of rubber materials.
  • Do not place it near high temperature heat sources (boilers, stoves, etc.). Heat can accelerate the deterioration of rubber materials.
  • Do not hang the O-ring on a nail, steel wire, etc., or hang it on a string, as this may cause the O-ring to deform.
  • Nitrile rubber (NBR) and styrene-butadiene rubber (SBR) may develop ozone cracks (cleavage-like cracks across the entire O-ring surface) when stored in an open or otherwise exposed state to the air.
  • In particular, avoid storing in the following conditions, as it will accelerate the occurrence of such cracks.
    Storing near electric motors (copy machines, etc.) that generate ozone easily.
    Storing of the product while it is stretched. (This includes storing with the O-ring installed.)
 

Storage period

ProductMaterialStorage period
Single rubber productNitrile rubber (NBR)10 years
Silicone rubber (VMQ)20 years
Fluoroelastomer (FKM)20 years
Sthylene-butadiene rubber (SBR)10 years

The storage period are for products that are stored indoors in standard packaging, away from direct sunlight, high temperatures, and high humidity.

Behind the Scenes

 

NOK has established the Shonan Development Center to further reinforce the material technologies it has cultivated over many years.
NOK believes that this center can conduct more comprehensive basic research than ever before, and that the company has established a system that enables it to develop materials
that meet an even greater variety of uses and requirements.

In addition, NOK is expanding internationally through its global branches and also completely rebuilt Kumamoto Plant, the hub of the O-ring production in April 2007,
with the aim of making a further leap forward. NOK is proud that this new plant is in a state where the company can aim for further quality improvement and stability by creating a better premises environment.


NOK's O-rings have already earned the trust of a wide range of industries around the world, but the company is not satisfied with the current situation and would like to continue to meet the diversifying and sophisticated needs of customers through continuous
material development and production of highly reliable and high-quality O-rings.
