SINGLE AND DOUBLE DISC COUPLINGS FOR SERVOMOTORS

The Zero-Max line of Servo Class couplings includes single disc SD and double disc SC models. Both styles are designed to meet the precision positioning requirements and high reverse-load characteristics.

SD models are said to provide a small package with high torsional and axial stiffness while SC models provide high parallel and axial misalignment capability. Both models have zero backlash, low inertia with a greater coupling torsional stiffness operating range to avoid system resonance in most applications.

Designed to handle the drive and resolution characteristics of servomotors such as ac, dc, or stepper and ac synchronous, these couplings have flexible metal stainless discs and keyless clamp-style mounting hubs. Both single and double disc styles require no maintenance and are said to be easy to install. Units are available with inch or metric keyless hub bores.

Available in eighteen sizes with torque ratings from 4.43 to 885 in. lb (0.5 to 100 Nm), the couplings are available with clamp style hubs with either inch, metric or combination bores. Bore sizes range from 0.157 to 1.375 in. (4.0 to 35.0 mm). The products are available with 3D CAD drawings and coupling sizing software on a CD ROM upon request.
