A manufacturer of thermoforming machines needed a holding brake. They wanted to continue to use a servo motor made in Japan and a gear reducer made in the USA but no one offered a brake that could go between the different faces of the two components. Faced with either costly design changes or abandoning one of these trusted components, the OEM approached Mach III for a solution.
Mach III solved the dilemma with this spring applied, air released friction brake. The output side of the brake (top photo) has a 1.625 Inch Shaft with standard keyseat to connect to the USA-made imperial gear box. The input side (bottom photo) has a 55mm bore and features a locking collar which connects the brake to the Japanese metric motor.
Mach III’s catalog model NEMA Frame clutches have a female input bore and male output shaft and are designed for coupling motors and gearboxes. But what do you do when you need to couple two components with output shafts, one metric and one imperial? Insert a custom designed Mach III clutch with NEMA housing that has a female input on both sides.
Specifications for Product No. C3C2R-002:
Torque Rating = 573 lb.in. @ 80 PSI
NEMA Frame Size = 143T/145T
Input Bore = 0.875 Inch with Standard Keyway
Output Bore = 32mm with Standard Keyway

A manufacturer of plastic thermoforming machinery needed a replacement for a troublesome caliper brake but no manufacturer offered a servo brake that would match the Japanese built servo drive (metric) and a U.S. made gear reducer (imperial). Mach III saved the OEM the expense of modifying the machine design by creating a c-face, spring applied brake to fit between the two components. This example has a 55 mm input bore and a 1.625 Inch output shaft. Torque rating: 6400 pound inches, 58 PSI release.
