Motor To Gear Reducer Drive Arrangement


Mach III offers catalog model brakes, clutches, combination clutch-brakes and torque limiters that are designed for mounting between a c-face motor and gear reducer in NEMA frame sizes ranging from 56C to 215TC. Our combination clutch-brakes can also be connected to a c-face motor and a sprocket or pulley can be mounted on the output shaft. All Mach III NEMA Frame models are completely enclosed. Standard aluminum, clear anodized aluminum and stainless steel finish options are available.

In addition to these standard NEMA frame sizes, Mach III offers IEC sizes and custom designs for unique mounting situations such as Imperial to Metric. Use the Explore Custom Products link below to learn more, or contact our engineering department to discuss your requirements.
