Mini-Disc coupling feature higher torque capacity over elastomeric coupling types. When sizing the Mini-Disc, ensure that the maximum torque for the application is under the allowable torque for the particular coupling size. Check the maximum bore, misalignment, and torsional stiffness ratings against the requirements of the application.
The MD (mini disc) Series coupling features a higher torque capacity over elastomeric
coupling types. The MD Series one piece clamping design allows for easy removal and
assembly. The Aluminum hubs and stainless steel disc materials allow for excellent
resistance to oil and other chemicals.
The MD Series design offers moderate torsional
stiffness for applications requiring repeatability. The MD Series also offers up to .020
inches of axial misalignment.
The MDS (mini disc spacer) Series coupling features a higher parallel misalignment
capacity over standard MD Series at .006 inches. The MDS Series also has the
highest parallel misalignment at .012 inches and angular misalignment at 2° of any of
the mini disc couplings.
The compact design of the MDSD (Mini Disc Single Disc) Series accommodates
applications that allow for a minimum amount of space for the coupling.
The MDSD Series
coupling also features a high torsional stiffness over the MD and MDS Series. The MDSD
Series also has the lowest inertia of the mini disc designs.
