Rotary Damper
Compact rotary damper for controlled soft-close hinge systems.
WW20H8S / Rotary Damper
WW20H8S is a rotary damper for controlled movement. The published dimensional reference is Ø19.85 mm body / 48 mm overall length, with a torque range of 1.0–3.0 N·m. These catalogue values provide a starting point for selection; the result in an assembly also depends on the moving load and pivot geometry.
The listed rotation information is CW / CCW variants. Compare the shaft or drive interface, available mounting space and operating angle with your design. Where more than one variant is available, confirm the required direction and torque before sample approval.
For a seat, lid or cover project, record the moving weight and its centre of gravity, then review the available space around the pivot. Confirm the selected direction and evaluate the closing movement in the actual assembly.
A rotary damper can be integrated into the hinge mechanism to control the closing movement of a toilet lid or seat. Match the torque and rotation direction to the moving part, and check the hinge fit and closing action in the complete assembly.
Application examples illustrate selection considerations, not automatic compatibility or project qualification.
