Wixroyd One-Way Hinges - S4005
What is...
One-way Hinges are a mechanical component that combines the functions of the one-way clutch and friction 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 chosen position. These are ideal as the door hinges on various types of lids for sheet metal, machine enclosures or office automation equipment.
Technical Specs
Bespoke shafts for standard and flange models
If you are making your own shaft for gear mounting, please use the shaft satisfying the following specifications shown in the table.
| Specification items | Specifications of the adaptable shaft |

| Materials | Heat treated steel |
Operation Enviroment
| Operating conditions | Operating enviroment |
| Temperature | -5°C to 60°C |
| Humidity | 90% RH or less |
Installation
Mounting
| Models | Mounting |
| Standard model | Insert the shaft to the one-way hinge and put the boss part of the hinge into the grooves of gears and other matching component. When operated, the hinge needs to be turned. |
| Flange 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 operated, the shaft needs to be turned. |
Mounting examples
General Guidance
Comparison with oil damper
| Head | Torque | Lid | Environment | Other |
| One-way hinge | Constant | Motion can be stopped at any position | -5°C to 60°C 90%RH | Wide torque setting range |
| Falls | Affected by environmental conditions |
Reliability
Torque is set as within ±10% to the nominal value before shipment. Guaranteed life-time is 20,000 cycle (1 cycle = 1 return motion).
| Test condition items | Test conditions |
| Speed | 13 strokes / min |
| Operation angle | 360° |
Caution
Care must be taken when mounting the One-way Hinge. The torque may be changed if an unbalanced load is directly applied in the radial or axial direction.
