Servo Class couplings feature zero-backlash, flexible metal stainless discs and keyless clamp-style mounting hubs. They offer high torsional stiffness with low inertia to avoid system resonance.

The single disc SD005 design provides a smaller package with greater torsional and axial stiffness than the double disc SC005 design that will allow for small amounts of parallel misalignment. Both require no maintenance and are quick and easy to install.

This smaller size Servo Class Coupling, along with the full range of sixteen other models, is designed to meet the precision positioning requirements and high reverse-load characteristics of today's applications. The coupling provides lower inertia and weight with a compact package design.

Additional features include clamp-style mounting hubs, available with inch or metric keyless bores, which make them the ideal mounting solution for a broad range of precision servomotors.
