Customer Delight

 

We do not only provide products, but also tackle each and every concern our customers may face
with PRECILENCE as the solution.

Customer Delight

Customer Delight

Want to assemble right away but must adjust shaft
diameter onsite to suit the bearing I.D.
Adjustment takes several days.
After assembly, must take time to adjust rotational
runout accuracy.
Isn’t there a way to cut out runout adjustment?

Quality Assurance

 

In order to guarantee product quality at a high level, we have carefully selected and maintained our measuring instrumentation also. Returning to measurement principles, we establish various measurement and quality assurance technologies.
Through designs using independently-developed equipment, we have made it possible to measure items not previously measurable, and acquire data previously unobtainable.

Human Resources

 

A dedicated PRECILENCE team establishes conditions to produce quality parts in each process, and works with a strong sense of responsibility and pride until the product warranty stage.

 

Production Environment

 

One major factor behind maintaining product accuracy is preparation of the right environment.
By adopting a constant-temperature/constant-humidity structure separated into zones by individual process, measurement error due to temperature change has been eliminated to the maximum extent.
We boast first-class cleanliness as a bearing plant and maintain an environment in which high-quality products can be produced with stability.
