There is danger of our living environment becoming polluted with environmental hormones and toxic substances without our even realizing it. We are doing our utmost to prevent the use of such substances in the materials used to make chains and in our manufacturing processes.

The problem of trash is one that weighs heavily on our nation. In the incineration and trash recycling processes, chains play a large role in conveyance and sorting.

Until now, chains have been covered in oil and noisy. We have developed chains that are quiet and do not leak oil to dispel that bad image.
