Our Technologies Realize Your Dreams One-Way Hinges RoHS Compliant One-way hinges are a mechanical component that combines the functions of the one-way clutch and torque limiter, and are a hinge that has a load torque for retaining a lid, etc. in one direction while freely rotating without load in the other direction. When used in door mechanisms, they can be used to make opening easy (only the weight of the lid) or to hold in any arbitrary position. These are ideal as the door hinges on various types of lids in OA related equipment.

One-Way Hinges Ｆ ａ ｕｅ ｅ ｔｒ ｓ １． Compact, thin and high-torque The width is 13mm for 0.1 to 1.0N･m type or 19mm for 1.0 to 3.0N･m type ;   therefore, it requires minimum mounting space. ２． Free stop   Capable of stopping a lid at any position and supporting its load. ３． Not easily affected by environmental conditions   Operation condition：-5℃ to +60℃, 90%RH ４． Wide torque setting range   A standard setting torque is from 0.1 to 3.0N･m by an increment of 0.1N･m. units within the range. Please consult us if you require other torque range specified above. ５． Two directions, R and L, are available...

One-Way Hinges Mounting Insert the adaptable shaft to the one-way hinge and put the boss part of the hinge into the grooves of gears and other matching component. When is operated, the hinge needs to be turned. Standard Model Set the flange part of the housing and then insert the adaptable shaft. You may make a "D-cut" at the edge of the shaft for mounting, when putting a gear. When is operated, the shaft needs to be turned.
