Awareness of environmental conservation is the most important objective for TOK. All of our products: Bearings, One-way clutches, torque limiters, and rotary dampers are carefully monitored during the production process.
We put the utmost effort into conserving the environment and having awareness of environmental issues because what we do to our planet affects us individually and collectively, now and for future generations.
1. We recognize the importance of environmental conservation and implement our production activities while taking its environmental impact into consideration.
2. We comply with all applicable requirements related to the environmental aspects of our company. In addition, we endeavor to protect the environment by setting voluntary standards as well, to improve our standards towards having as little environmental impact as possible.
3. Each individual must construct and improve the environmental management system to improve performance and prevent further pollution of the environment.

5. Continuously setting environmental objectives and targets to improve the environment.
6. Each individual of TOK is aware of these policies and strive reach the goals of our environmental management system.
7. This policy is disclosed to the general public on our website and can be obtained at our reception desk.
We will plan and propose new technologies and services characteristic of our organization. We test these new technologies using machines that focus on “control rotations” and ensure that the results meet your standards. Through our vast experience accumulated through past client interactions, and inventions in a wide range of industries, we will work with you in ensuring you get the best possible design and performance, at the lowest possible costs.
A product design begins by evaluating a trial production. We independently process components, resins, and metals used for trial productions. We keep our client’s requests in mind during these trial productions, and test to ensure that we achieve your desired results.
We at TOK take pride in our development structure and our belief in the concept of value analysis: making sure that our clients are getting the desired results at the lowest possible costs to them, regarding material, design, and implementation. To stand on this belief of ours, we thoroughly perform evaluation tests for each product. To ensure our strict evaluation standards, we have developed our own evaluation equipment independently. We use testing machines that were produced based on our expert experience to perform daily evaluations that guarantee superior performance for all our products.
In manufacturing plastic products, building a mold is one of the most critical process. To meet a wide variety of customer needs, TOK utilizes various machine tools to build molds of high precision.
“Create an Environment That Produces Excellent Products” is one of our most central themes, and as such, TOK has continued to improve productive facilities and production methods. We design and manufacture production equipment such as auto-assembly machines (for bearings and one-way clutches) built while conducting improvement. In-house designed production equipment and rigorous quality control structures have built a highly reliable and efficient production system. In addition, to build a global quality system, we have positioned the Yamanashi Plant as the main production plant, the top standard of our production process, which from our overseas manufacturing subsidiaries then apply that same top level of production and quality control to match that of Japan.
