Disaster prevention and response, no power supply needed, small inline reducer that can be driven by electric tools.
SRM/SRE Series
No need for brake or stopper! It can hold the load while stopped and allows work or experiments to be conducted at an angle. The input and output shafts are aligned in a straight line, achieving space-saving design!
This is a compact inline reduction gear equipped with our company's self-locking mechanism (Shoji-Lock). For example, it can hold a load even if the movement is stopped during the ascent, rotation, or tilting of the device, making it suitable for requests such as wanting to conduct experiments or perform tasks at a stopped position. Another feature is that while conventional worm reduction gears with self-locking functions require a considerable amount of space due to the input and output shafts being orthogonal, our design allows the input and output shafts to be in a straight line (inline), enabling a lightweight, smart, and compact design that is easy to integrate into various devices. The lineup can be selected based on output shaft torque and reduction ratios, with options available for output shaft torque ranging from 5 to 100 kgm (load × torque arm). Some products are also available in all stainless steel for cleanroom compatibility. The basic model is coated with black Teflon, which is resistant to rust. Additionally, it can operate and maintain load even without power during emergencies. It is being introduced as a mechanical component in various fields such as defense and military, plant-related applications, semiconductor manufacturing equipment, automotive assembly lines, and device lid opening and closing.

Company information
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.
