D6F4G-003_x500The application for this spring actuated holding brake required a minimum 3,300 lb-in torque capacity.  Our engineers first recommended the Mach III catalog D8F3K-STH,  however, the machine design could not accommodate the 11.75 inch flange diameter of this standard model.

To accomodate the radial space constriction, Mach III used the D6F3G-STH brake as a base and incorporated additional friction surfaces. The result was a brake with 4,405 pound inches of holding torque within a 9.53 inch diameter.
