Rotary dampers utilise the principle of fluid resistance to reduce the speed of moving parts and hence provide controlled opening and closing of small lids, drawers, panels and covers. The oil viscosity (or thickness) provides the “braking” or torque force in Wixroyd rotary dampers – differing viscosity results in differing torque and hence braking force capacity.
Wixroyd rotary dampers are extremely compact and are used in many different applications; glove boxes, storage compartments, arm rests, music centres, electronic and scientific equipment and much more. When used with a toothed rack, such as Wixroyd Q3150, rotary dampers can be provided dampening on linear planes.
With a range of different damping speeds (torque force Kgf.cm), a simple torque calculation is used to specify the correct Wixroyd rotary damper. Our technical engineers would be delighted to discuss your requirements with you and recommend the best options for your application, so why not give us a call to find out more?

Bi-directional rotary dampers. Up to 400 gf.cm torque Creates a smooth movement and dampening in applications.
Rotary dampers utilise the movement of fluid forced from one chamber to another via a rotor. Dampening speed is dependent upon the viscosity of the fluid and the diameter of the fluid aperture
Through the use of toothed plastic rack no. Q3150, rotary dampers with gears can be used to dampen on a linear plane rather than the normal dampening directly at the shaft.

To calculate the torque for your application, the following measurements are necessary.
t (torque) = w x 0.5 x h
h = length from pivot point to end of lid (cm)
w = weight of the lid (Kg)
Torque force stated per product (see individual product pages, is the maximum torque to which the specified part can be exposed before the dampening force yields and hence dampening is overcome
Damping direction is determined whilst looking directly onto the output shaft
Avoid side loading of the disk damper output shaft in order to maximise effectiveness.
Important Note: Once calculation has been made choose a disk damper from our range which can accommodate the newly calculated torque of thr application. Use the damper closing speed graphs opposite to confirm that the rpm given at the corresponding torque value matches the desired lid closing speed. If the desired rpm is beyond the capacity of the selected damper, then select another damper with a higher torque rating and re-test
If the rpm is too slow select another damper with a lower torque rating and re-test.
Follow the Torque calculation formula and utilise the following torque closing speed graphs to ensure the selected rotary damper best suits your application.
