RDZ163H-200 Rotary Damper for Soft-Close Toilet Seat Systems
The RDZ163H-200 is a 20 mm toilet seat rotary damper set with a 1.0–3.5 N·m torque range and 0°–110° opening and closing angle. Its shell and shaft use PA66+50%GF, with a zinc hinge support specified for the set.
It is intended for toilet seat and lid mechanisms where the damper size, shaft interface, hinge geometry and required torque are matched before production. For OEM projects, we can discuss torque requirements as well as tag, label and logo customization.
RDZ163H-200 Technical Specifications
Confirm the damper dimensions and required torque against the actual toilet seat and hinge system before ordering. The 1.0–3.5 N·m range provides multiple torque choices, but the final selection must match the mechanical design of the seat and lid.

Model-Specific Test Evidence for RDZ163H-200
Slow-Drop Tests
CN20D product information states that the damper set has undergone no fewer than 50,000 slow-drop test cycles.
High-Force Tests
The model information also states 20,000 high-force tests as part of its durability verification.
Reinforced Structure
Both the specified shell and shaft use glass-fiber-reinforced PA66, combined with zinc hinge support.
For OEM approval: cycle count alone does not define the complete validation requirement. Include the required torque, test load, seat configuration, fixture conditions and acceptance criteria in your project specification so the sample can be evaluated against the intended toilet seat system.
What Must Match Before You Select RDZ163H-200?
A rotary damper cannot be selected by product name alone. RDZ163H-200 should be evaluated against the dimensions and torque required by the actual toilet seat, lid and hinge assembly.
- Required damping torque within the 1.0–3.5 N·m range.
- Available installation space for the 20 mm damper size.
- Required seat and lid opening angle within 0°–110°.
- Damper shaft and mating hinge interface dimensions.
- Seat or lid model being developed or matched.
- Required durability and force-test conditions.
- OEM tag, label, logo or other project identification needs.

Where Does the RDZ163H-200 Toilet Seat Damper Fit?
Use CN20D as a candidate where the toilet seat hinge system requires a 20 mm rotary damper and a torque within the specified range.
Integrate the damper with a matching hinge design after confirming torque, dimensions, shaft interface and opening angle on the actual seat assembly.
For replacement sourcing or redesign, compare the existing component dimensions, torque requirement and hinge interface before approving CN20D.
For UF or PP toilet seat programs, the damper should still be selected by the actual mechanical requirements. Material-specific alternatives are available when they provide a better match for the seat design.
