[Strength of products/technologies]
We will cater to every need for racks. Machines need different kinds of racks in terms of sizes and shapes depending on their applications. We have a track record up to M50, and we respond to various needs. We also welcome joint development with the customer. Whatever the size or requirements, please consult us. 
We have introduced a rack gear grinding machine. This has made it possible for us to offer a ground gear rack that realizes high precision and high rigidity, and that is resistant to wear. We are ready for higher requirements from our customers!

[Representative's message]
We have focused on, the rack and pinion system, which is one of the direct acting apparatuses, and we are advancing research, development, and production. Our gears cannot do anything on their own. However, when two or more gears are combined, they can do great work with the power they convey. With this in mind, we developed our carburized ground helical rack. It can replace ball screws, linear guides, and other direct acting apparatuses. Please try out this great product. Once you try it, we are confident that you will see the potential it can offer. 

[Company structure for market development/overseas expansion]
In 2010 we created a foothold in the Kanto region. This was done through the Sales Channel Coordination Project by the Kanto Office of the Organization for Small and Medium Enterprises and Regional Innovation, Japan (SMRJ). In July 2012 we opened a sales office in Tokyo. We are continuing our efforts to develop sales channels for major enterprises.
For overseas expansion we participated in an expo in Indonesia (Jakarta). In 2013 we went to Southeast Asian countries on an inspection tour with feasibility study support. Starting from 2012 we plan to recruit personnel with language abilities to act as staff responsible for overseas sales channel development.
