Specialty dampers

FRX-A1 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
FRX-A1 damping charateristics 1. Temperature characteristics A leading damper's torque varies according to the operating environment. In general, as shown in the graph to the right, the torque decreases as the ambient temperature increases, and the torque increases as the ambient temperature decreases. This is because the viscosity of silicone oil inside the damper varies according to the temperature. When the temperature returns to normal, the torque will return to normal as well.
