Disk Dampers Q3200 - Q3260
What is...
Solutions for controlled opening and closing motion
Wixroyd Disk Dampers offer controlled opening and closing of lids, drawers, covers and much more. They provide a range of solutions for a variety of applications, creating smooth movement and function. Though unnoticed in many applications, Disk Dampers are a vital part of many products bringing quality, safety and durability.
Disk Dampers provide quality movement enhancing both touch and feel. Available in uni-directional (single) dampening or bi-directional (double) version.
Introduction
Disk Dampers utilise the principle of fluid resistance to reduce the speed of moving parts. The oil viscosity is utilised to provide the "braking force" of the damper. The torque or "braking force" can be adjusted by changing the viscosity of the oil.
Applications
- Loading trays for DVD, MD players.
- Arm rests, center consoles, glove boxes, handles and storage compartments in passenger vehicles.
- Camcorders, mobile phones and small personal devices.
General Guidance
Operating Principles and General Specification
Disk 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, Disk Dampers can be used to dampen on a linear plane rather than the normal dampening directly at the shaft.

Technical Specs
Torque Calculation
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.
Note
Damping direction is determined whilst looking directly onto the output shaft.
Important
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 the 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.
Torque graphs for temperature and speed
Follow the torque calculation formula opposite and utilise the following torque closing speed graphs to ensure the selected Disk Damper best suits your application.

Knowledgebase Questions
The MTBF (Mean Time Between Failures) measure is not applicable. Unless the dampers are used out of specification, the dampers don’t suffer catastrophic failure. However, the more revolutions they do the weaker they get. As such, there is no recovery between failures, just a decline of strength over time, which is normally well over the given life expectancy of 50,000 cycles.
Thank you for your enquiry. Yes, the Q3260 damper spins freely in one direction and exerts a damping force in the other.
