Advanced ExampleConcept of Swivel Hinges (HG-S) Operating Force

Since the mass of the lid/door is theoretically irrelevant when rotating in the swivel (horizontal) direction, the following formula can be used to calculate it.

Operating force = Torque value ÷ horizontal distance from center of rotation to operating point

Example

Swivel torque hinges HG-S50-34 (torque value 5.0±20%N-m), mass=3kg
If the horizontal distance from the center of rotation to the operating point is 450 mm,
the operating force is 5.0 N.m ÷ 450 x 1000 = 11.11 N.

In addition, because the variation of torque is ±20%, a swing to the lower limit will
result in 5.0N-m x 0.8 ÷ 450 x 1000 = 8.89N, and a swing to the upper
limit will result in 5.0N-m x 1.2 ÷ 450 x 1000 = 13.33N.

In other words, it is believed that it can be operated at 8.89N to 13.33N.

The formula is different for torque stays that do not have a torque generating axis
at the center of rotation.
Please use the torque stay selection tool.
