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.
This spring engaged, air released friction brake was designed at the request of a thermoforming machinery manufacturer in Taiwan who needed to assure that a forming platen is held stationary in the absence of air pressure. Communicating by email across 7,800 miles and 12 time zones, Mach III’s engineers were able to obtain all the details about the application as well as the dimensions of the servo motor and gearbox the brake would go between.
Within a couple of days a design and quotation were presented for this holding brake which has 2,409 pound inches of torque. The brake connects directly to a Yaskawa SGMGV-IE 15kw servo motor on the input side and a Lenze GKS-11 3W gearbox on the output side.

In addition NEMA Frame mounted models, Mach III also produces clutches, brakes, clutch-brake combinations and torque limiters to IEC Flange standards. The model pictured is a combination air applied clutch – spring applied brake.
Part Number: X5C2R-004
IEC 100 Frame, B5 Flange
28mm Input Bore and Output Shaft
Clutch Torque: 495 lb-in @ 80 PSI
Brake Torque: 197 lb-in, 20-30 PSI Release
NEMA and IEC models are available also a variety of finishes: aluminum, anodized aluminum and stainless steel, making them suitable for food processing and packaging applications.

What makes this Mach III brake custom? Not much, really. It is basically a catalog model D5C3R-21H spring applied brake with an output shaft diameter of 1.125 Inch instead of 1.375. A minor change, but when the brake must be mounted between a 213TC NEMA frame motor and a 182TC NEMA frame gear box it is a major difference. No longer does the client have to purchase a brake, disassemble it, turn down the output shaft and put it back together. This Mach III brake is out of the box and on the machine with a lead time of only 3 weeks.

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.
