FYT/FYN-D1/D2

Vane dampers

FYT-FYN-D1-D2 Series
Bansbach vane dampers and dashpots are used to dampen drives, control speed, and many other applications. Our rotational viscous dampers are maintenance free and the most durable units on the market. Bansbach silicone oil viscous dampers are available in either fixed rate or adjustable models. On adjustable vane dampers adjustment is made with an integrated set screw.
The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions. In vane dampers with continuous rotation, a fluid damping is produced by the shearing or braking force of silicon fluids resistance between the surfaces of a rotor and a stator. The damping moment is determined by the viscosity of the fluid and the size of the orifice or gap. The damping characteristics can be customized by changing the viscosity of the silicon fluid or by changing the structure of the rotor and stator. vane dampers life-cycles are typically in excess of 50,000 cycles. The service life may be significantly higher or lower, depending on the application. After extended life cycles the dampers still produce over approx. 80% of their original damping moment.

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 viscosity of the oil inside the damper varies according to the temperature. When the temperature returns to normal, the damper characteristics will return to normal as well. The changes in the time it takes for the lid to close are shown in the graph to the right.  characteristics
The damper's working angle is ±52.5° with respect to the attachment flange. Please determine where to attach it according to your needs. Also, rotating the damper beyond this angle will cause damage to the damper. Please ensure that an external stopper is in place..
 diagram
The FYN-D1 series is a fixed type; its torque is non-adjustable. The torque range is customisable between 2 ~ 20Nm by changing the oil viscosity.
