Couplings accommodate substantial misalignment
Discflex miniature disc couplings comprise an assembly of two anodised aluminium hubs, a centre spacer and multiple flat stainless-steel disc springs to transmit torque.
The thin discs allow for a substantial amount of misalignment between shafts, while remaining rigid under torque loads.
Parallel misalignment is accommodated by the double disc style or by two single disc couplings used in tandem.
Disc couplings are high performance motion control couplings with zero-backlash, excellent speed capabilities up to 10,000rev/min, strength and torsional stiffness characteristics, as well as low inertia for today's highly responsive systems.
Double disc couplings are used in typical servomotor lead screw applications, whereas single disc couplings can be used when a longer distance is required such as on gantry systems.
Double disc styles are available with either an anodised aluminium centre spacer or an electrically isolating acetal centre spacer.
Both disc style couplings are offered in standard sizes with outside diameters from 15 to 57mm in both Nomar clamp style and set screw style, and bore sizes ranging from 0.125 to 1.25in in the inch series and 3 to 30mm in the metric series.
