Inline reduction gear with self-locking function for tilting and reversing devices, 50 kg·m.

Equipped with a unique self-locking feature to hold the load on the output side when stopped! Compact and ideal for tilting and inversion devices! Supports a permissible rated holding torque of 50 kgm!

The "S-Reducer," which is being adopted across various industries due to its higher efficiency and compact design compared to existing worm gear reducers, has improved its allowable rated holding torque from 40 kgm (392 Nm) to nearly the same size at 50 kgm (490 Nm). Its greatest feature is the unique self-locking function (shoji-lock), which allows for the retention of loads even if the movement is stopped during the raising, lowering, or rotation 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 speed of rotation and input torque, so please feel free to consult us. *For more details, please visit our official website or feel free to contact us.*

Railway-related: Load retention and operability during tilting and inversion! Compact inline reduction gear.

No need for brake stoppers! It holds the load when the rotation stops, allowing work and experiments to be conducted while tilted. The input and output shafts are aligned in a straight line, achieving space-saving design!

This is a compact inline reducer 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 reducers with self-locking functions require a considerable amount of space due to the input and output shafts being orthogonal, our design has the input and output shafts aligned in a straight line (inline), allowing for a lightweight, smart, and compact design that can be easily integrated into various devices. The lineup can be selected based on output shaft torque and reduction ratio, 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 clean room and vacuum equipment compatibility. The basic model features a black Teflon coating that 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. It is rated IP65, making it resistant to dust.
