Bi-directional No-back clutch_SR2
TOK has developed a new type of bi-directional no-back clutch, named the SR2. The SR2 provides controlled motion to adjust the height at any position. Through its inverse interrupting mechanism, this breakthrough technique conducts driving from the input shaft to the output shaft and locks the input in place even if the drive is stopped. Thanks to this new mechanism, you can easily lift heavy objects and lock them precisely into position. This new control motion is perfect for applications such as adjustable tables, handicap sinks, and more.

Benefits:
･ No power supply
･ Easy operation
･ Ready to install
･ Competitive price

Finger Pinch Guard Preventer for sash and slide windows_SR8
 | Under development 　
Finger Pinch Preventer "SR8" has been developed for sliding doors, sash windows, and other window applications.
When a door or window is closed forcefully, the stopper automatically activates to reduce speed and prevent sudden closure. This helps protect users from finger-pinching injuries and enhances safety in schools, hospitals, stores, and other high-traffic environments. This product is made-to-order so the design can be modified to meet your needs, such as installation method, reaction speed, etc.

This product is not yet available for sale.
If you are interested in purchasing this product in quantities of several thousand units, please contact us using the inquiry form.


Benefits:
・A reliable deceleration mechanism works even with vigorous high-speed sliding, preventing dangerous finger pinching accidents.
・The stopper can be activated automatically without special operation.
・Since rotary dampers are not used, the design is not affected by environmental factors such as temperature variations.
・Speed can be adjusted by custom design.
