Specialty dampers

FHD-B1-B2 Series
Bansbachs Specialty dampers are a superior alternative to coil springs or rubber bump stops for energy absorption and linear deceleration. We offer many different models from mild to extreme. Our specialty dampers are the perfect solution for a wide range of applications, from a simple cabinet door, to the corrosive environments of the medical field, or the extreme environment of industrial machine equipment. Bansbach specialty dampers are designed to absorb the impact with no bounce back. This steady, gradual deceleration allows faster cycle rates, increased equipment life, and higher production rates while reducing maintenance expenses.

Damping Characteristics
FHD-B1-B2 damping charateristics 1. Temperature characteristics Damper characteristics vary according to the ambient temperature. In general, the damper characteristics become weaker as the temperature increases, and become stronger as the temperature decreases. This is because the temperature of the shaft bush inside the damper varies according to the temperature. When the temperature returns to normal, the damper characteristics will return to normal as well.
2. Speed characteristics The speed characteristics of a friction-type hinge damper are shown in the graph below. The damper torque is determined based on the speed characteristics at 2rpm.
