They offer zero-play operation, a high torsional stiffness and are easy to mount in even difficult installations. Typical applica- tions are in motion control, e.g. in positioning systems, transport systems, optical systems, etc. A main feature of these cou- plings is the ability to absorb radial displacement without bending. Since there is no persistent force from bending, "floating" moulded disc which absorb deflections. At the same time it acts as a mechanical safety fuse. Under serious overload, the disc fails, fractur- ing cleanly, and thus provides some degree of protection to disc is easy to change and the entire construction, in which the parts can bepulled from one another, enables disassembly without removing the drive discs from axles. These couplings require that both axles have sufficient support. They must not be used on long unsupported axle lengths and must not be used in pairs with an intermediate unsupported axle.

*The couplings can withstand a minimum of 10G reversals of operating direction at these levels The maximum recommended rate of rotation for all the couplings is 3000 rpm. L = Depth of axle hole, L2 = Distance between endsof axle. Material: Aluminium alloy with alocrom corrosion protection. AcetaI discs. A 4 to 6.35 mm adaptor is available for 4mm axles.
