Inline reduction gear with self-locking function for tilting and reversing devices, 25 kg·m.
ＳＲＭ０２５ ＳＲＥ０２５
Equipped with a unique self-locking function to maintain the load on the output side when stopped! Compact and ideal for tilting and inversion devices! Supports a permissible rated holding torque of 25 kgm!
The "S-Reducer," which is being adopted across various industries due to its high efficiency and compact design compared to existing worm gear reducers, has improved its allowable rated holding torque from 20 kgm (196 Nm) to nearly the same size at 25 kgm (245 Nm). Its greatest feature is the unique self-locking function (shoji-lock), which allows for the retention of loads even when the movement is stopped during lifting, rotation, or tilting of equipment. This makes it ideal for applications where it is necessary to hold or work at a stopped position. It has been introduced as a mechanical component in various areas such as semiconductor manufacturing equipment, automotive assembly lines, and plant lid opening and closing. Another feature is that, unlike the aforementioned worm gear reducers, the input and output shafts are aligned in a straight line (in-line), making it very compact and easy to integrate into equipment. We offer a variety of reduction ratios according to the rotation speed and input torque, so please feel free to consult us. *For more details, please visit our official website or feel free to contact us.*

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.
