Low inertia miniature couplings deliver high torsional stiffness

October 1, 2010 By Leslie Langnau Leave a Comment

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.”

Performance specifications for Servo Class couplings:
