The website has been renewed.
A completely new self-locking deceleration mechanism "shoji-lock" that allows you to hold the load at the desired position without the need for brakes. We have separated the lineup of deceleration devices, winches, and rack jacks equipped with this mechanism into individual pages. Additionally, each page includes videos. You can check the series of movements: drive → stop → load holding → restart. There are also plenty of highlights such as an explanation page for "shoji-lock" and development stories. Please take a look. We have also fully revised the catalogs for each product. They are available for download on our website. Please make use of them.

Opening today! We will be exhibiting at the Technical Show Yokohama 2020 (Venue: Pacifico Yokohama).
We will be exhibiting at the "Technical Show Yokohama 2020," which will be held from today, February 5, until February 7 (Friday) at the Pacifico Yokohama Exhibition Hall. We will showcase actual machines such as "winches" and "reduction gears" equipped with our uniquely developed self-locking reduction mechanism "shoji-lock," and we will introduce their features. Please feel free to stop by. (Booth number H-28, within the Shonan Wide Area Urban Administration Council booth)
About庄司歯車エンジニアリング
The new self-locking mechanism (shoji-lock) built into the reducer, winch, and linear rack jack is lightweight, compact, and achieves space-saving!
The load-holding function equipped reduction mechanism (shoji-lock) has been developed for application products such as winches and rack jacks since the early 2000s. Steady sales activities have borne fruit, and it has begun to be adopted for various applications. Unlike conventional worm reduction gears with self-locking functions where the input and output shafts are orthogonal, our design features them in a straight line (inline), allowing for a compact design and space-saving, which has received high praise and resulted in a diverse range of practical examples. (Patents have been obtained in Japan, the United States, the EU (Germany, France, the UK), China, South Korea, and Taiwan.) Furthermore, starting in April 2023, we launched a new overseas parts procurement business, beginning with Vietnam. Currently, a majority of our parts are procured overseas, and leveraging our achievements and network, we aim to assist companies struggling with cost reduction in parts procurement.
