Servo Class Couplings come in miniature sizes.

Press Release Summary:

Single-disc Model SD005 and double-disc Model SC005 are 16 mm in diameter with operating torque of 4.43 lb-in. and maximum speed of 10,000 rpm. Suited for miniature servomotor systems, units feature zero-backlash, flexible metal stainless discs, and keyless clamp-style mounting hubs. Model SD005 provides smaller package with greater torsional and axial stiffness than Model SC005 that allows for small amounts of parallel misalignment.

Zero-Max Servo Class Couplings Available In Miniature Sizes - Single And Double Disc Models Available For Servomotor Systems

Plymouth, Minnesota: Zero-Max has expanded its line of Servo Class couplings to include a new smaller 16 mm diameter size with operating torques of 4.43 in-lb. in both single SD and double disc SC models. Called the SD005 or SC005, this coupling is designed for use in miniature servo applications. Designed to handle the drive and resolution characteristics of servomotors such as AC, DC, or Stepper and AC synchronous.

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.
