Product Description

This miniature damper has three mounting holes, making it easy for customers to install. The damping wheel and buffer have shockproof effects and slow down the door opening and closing speed, making it smooth and effective in reducing noise generated during product use. The damper can enhance the overall product quality and extend the product's lifespan.

Product specifications:

Model	Torque	Damping rotation direction
LF-11E-30G	30±10gf.cm	360° rotation (bi-directional)
LF-11E-40G	40±10gf.cm	360° rotation (bi-directional)
LF-11E-50G	50±10gf.cm	360° rotation (bi-directional)
LF-11E-60G	60±10gf.cm	360° rotation (bi-directional)
LF-11E-70G	70±10gf.cm	360° rotation (bi-directional)
LF-11E-80G	80±10gf.cm	360° rotation (bi-directional)

Note: 1) The marked torque is based on testing conditions of temperature at 23℃ and humidity at 80%, with a motor speed of the test stand at 36 revolutions per minute, measured after the damper rotates for five circles.
2) Torque customization can be provided by changing the viscosity of the damper grease.
3) Maximum operating temperature range of the damper: -40℃ to +90℃.
4) This series of dampers can provide gear customization.

(Damper characteristics)

A. Temperature characteristics:
The torque generated by the damper will change under the influence of environmental temperature. This is because changes in temperature affect the viscosity of damping oil, causing torque output to decrease with rising temperatures and increase with falling temperatures. When the temperature returns to normal, torque also returns to its original value.

B. Speed characteristics:
The torque of the damper will also change when using different rotational speeds. Generally, as rotational speed increases, torque also increases; as rotational speed decreases, torque decreases as well. Additionally, starting torque differs from standard torque.

Specific usage methods for gear dampers

A. Gear meshing with rack (linear motion of workpiece)

B. Gear meshing with gear (rotational motion of workpiece with angle limitation)

C. Gear meshing with gear (no angle limitation)

D. Workpiece directly connected to damper rotating shaft
