SMC & SSC Series Bellows Couplings
MW Component's SMC Flexible Shaft Couplings meet rigorous requirements of precision positioning and motion control instrumentation. SMC flexible shaft couplings use Electrodeposited Bellows Technology to ensure precise measurements and tolerances with an all-metal construction. Bellows couplings have zero backlash, torque ranges from 3.7 Ncm to 2471.8 Ncm, low elastic windup, zero cyclic speed variation, low side thrust, and low movement of inertia.
SMC (adhesive assembly) and SSC (soldered assembly) bellows couplings can be used in applications that require angular misalignment or parallel misalignment. The bellows technology offers the greatest combined misalignment value of any coupling on the market, resulting in simple installation.
CAD files for stock and standard SMC and SSC Series bellows couplings are available for download in MW OnDemand.

Custom Manufacturing
Custom Bellows Couplings
Custom bellows couplings offer many benefits including, choice of material composition, simplification of assembly, and customizable attachments and tolerances suited to your specific end-use.
MW specializes in custom component manufacturing, providing you with the right features to ensure proper performance. Whether you need to eliminate endplay or spring, ensure zero backlash, need to increase torsional stiffness, or reduce windup, we can create the right custom coupling for your specialized need made to your exact specifications.

Bellows Coupling Manufacturing & Configurations
Manufacturing
SMC (adhesive assembly) or SSC (soldered assembly) couplings can be installed in two common configurations. Two set-screw at 120 degrees apart can connect directly to customer instrumentation or an integral clamping hub can also be chosen from our standard product line. Our standard end pieces are manufactured from high-strength aluminum to ensure operation in robust applications. Bore sizes are available from 2mm up to 25.4 mm (1 inch).
MW Components produces a variety of standard and custom couplings from bellows couplings to Helical beam couplings. To view a side-by-side comparison of all the standard couplings we offer, review our Couplings Comparison Guide below.
