Damper Flat Plastic Hinges
- Volume Discount
·It closes slowly, increasing safety.
·There are two types of torque generation directions: opening (clockwise) and closing (counterclockwise).
·Movement in the opposite direction of torque generation is also smooth.

- The operating angle is 115°. Please place a stopper such as a door stay to prevent the door from opening or closing beyond this limit.
- Please use within the applicable load torque range. Using beyond the applicable load torque range may cause damage.
- Horizontally align the axes of each hinge.
■How to Select a Damper Hinge
When selecting, you will need to calculate the maximum torque based on the size and weight of the lid you are installing.
The lid in a horizontal position generates maximum torque as shown below.
Calculate maximum torque according to the following formula before selecting a damper that satisfies the specifications.
* It is assumed that the center of gravity is in the center.
[Formula]
Max. torque T = L (door dimension: m) / 2 × m (weight kg) × 9.8 (Newton N)
Example: When L = 0.2 m and m = 10 kg
Max. torque T = 0.2/2 × 10 × 9.8 = 9.8 N⋅m
