FRL-A1/B1

Specialty dampers

FRL-A1-B1 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.

Principles of Reverse Lock

It is a click mechanism part that incorporates the principles of bearing clutch. Although the damping direction can be either clockwise or counter-clockwise, one side is always locked and the other damping direction is in a free state. For example, when opening and closing a lid on a piece of furniture, such as the one shown below, the lid is in a free state when it is lifted up to open, and a lock torque is applied in the closing direction the lid can be locked in at any angle. To close the lid, applying a small amount of force will release the lock, allowing the lid to close.

Application examples
Diagram 1 :
When a lid is lifted, a locking torque is applied in the closing direction, and the lid can be locked in at any position.
Diagram 2 :
When pressure is applied to the lid in a closing direction, the reverse lock is released and the lid can close freely.
