Coupling for special environment
Couplings that can be used in special environments such as clean room, vacuum, high temperature (80 ° C or higher) are available.

● Low particleThe amount of attached particle is ultra low.
This is directly available in a cleanroom. This does not bring contaminated matters into a cleanroom.
● Vacuum-supportedA material with which outgas production in a vacuum environment is small is used.
If misalignment becomes larger due to vacuum pressure difference,MOHS MOP, for which larger misalignment is permitted, are recommended.
● Less outgasMaterials with which production of outgas that causes chemical contamination under atmospheric environment is small are used.
● Heat resistantThis is available even in an environment of high temperature（ 80℃ or higher）
Elongation or deflection of a shaft associated with thermal expansion may increase misalignment. If misalignment becomes larger, MOHS MOP, for which larger misalignment is permitted, is recommended.
● Chemical resistantMaterials superior in chemical resistance are used.
Analysis of outgas
*Both inorganic gas and organic gas are not more than the lower limit of determined amount and are not detected.
Change in static torsional stiffness due to temperature
This is a value for each product under the condition where the static torsional stiffness at 20°C is 100%.
