The 16 mm diameter size Servo Class coupling has operating torque of 4.43 in.-lb in both single (SD) and double disc (SC) models. They suit applications that need high torsional stiffness and low inertia.

The SD005 model delivers 43.3 torsional stiffness and 0.0009 in.lb² moment of inertia. The SC005 model delivers 30.5 torsional stiffness and 0.0013 in.lb² moment of inertia. All Servo Class couplings have zero-backlash, flexible metal stainless steel discs, and keyless clamp-style mounting hubs. Their robust design is maintenance free and they are easy to install.

The miniature sizes perform in all types of smaller servo motor applications including medical, electronic and assembly systems. “Reduced size doesn’t imply lower performance for these couplings,” reports Robert Mainz, Zero-Max sales manager. “They are as effective as any of the 18 larger sizes in the Servo Class coupling product line. They are a better option than beam style couplings.”

MISUMI Coupling types include high precision Single Disc and Double Disc Clamping models, many of which may be used with servomotors.  Also offered are Oldham, Slit and N Couplings, as well as Jaw, Sleeved, Bellows, and Resin types, in a variety of sizes and configurations.

The SCXW is a Double Disc type precision disc clamping coupling with high torque but no backlash.  Its torsional rigidity is up to 26% higher than conventional (standard) disc clamping couplings. It suits applications requiring fast positioning precision.  All the bolts are trivalent chromate plated and suitable for use in clean environments.

The MFJGWK is available as a high rigid Oldham coupling, set screw type. The MFJCGWK is a high rigid Oldham coupling, clamping type.  Both products feature an aluminum bronze spacer and have a keyed bore.  These couplings have allowable torque 2X higher compared to resin spacers.

The SCOC is a short Oldham coupling, clamping/spacer type. This space-saving version works with miniature devices because it is 17% shorter than conventional types.

Most MISUMI Couplings ship in six days, with the exception of the new High Rigid Oldham Couplings, which ship in eight days.  Some couplings offer optional express shipping for faster delivery.

Huco Dynatork, an Altra Industrial Motion company, offers the worlds most comprehensive range of small precision couplings from a single manufacturer. Huco’s precision couplings are ideal for use in high-end servo drives, pulse generators, scanners, X-Y positioning slides, high speed dynamometers, measuring instruments, robotics, machine tools and in many other applications where specific dimensional or performance criteria is required.

Because there is such a wide range of different motion control couplings from which the design engineer can choose, Huco offers a complete Design Guide to coupling performance characteristics on the company’s website.

The website also contains a unique Coupling Selector designers can use as a tool to identify the coupling types that meet their design criteria for angular, radial or axial misalignment, or a combination of all three. The interactive tool helps designers understand whether they need a bellows, membrane, sliding disc or helical beam, or another design.

The Coupling Selector takes the key information provided about the application and presents all the couplings that fit the criteria, with a link to the detailed specification of each coupling. Selection is based upon coupling type (mechanism), dimensions, shaft connections, performance, displacement and other conditions.
