Double C-Face Coupler Brakes

Double C-face brakes use a self-contained design that support a range of coil voltages and function as a coupler between standard C-face motors and standard C-face gear reducers.

Stearns offers two types of general purpose double C-face industrial brakes:

Use Cases for Double C-Face Brakes for NEMA C-Face Motors

Stearns provides a general purpose line of double C-face motor brakes in accordance with the National Electrical Manufacturers Association (NEMA) standards. Double C-face brakes present a simple solution for coupling a C-face motor to a C-face gear reducer and support a range of rotational force requirements with torque support spanning from 1.5 to 105 lb-ft. General purpose double C-face brakes at Stearns are intended for indoor or outdoor use primarily to provide protection against dust, rain, ice formations and other natural elements.

How Does a Double C-Face Coupler Brake Work?

Stearns NEMA double C-face coupler brakes are a style of brake constructed in a safety-focused fashion which protects employees and critical mechanical parts in the event of a system failure by powering off and pausing an industrial operation until the system error has been resolved.

Benefits of Stearns Double C-Face Brake Couplers

Coupler benefits include:

Spring set, electrically released
Rugged 4-stud design for simplified mounting
Simple wear adjustments that provide easy maintenance
Standard or dust-tight, water-proof enclosures available
Sturdy construction for long, quiet operation
Optional space heater

The largest advantage of a double C-face brake is that it easily attaches to a standard NEMA C-face motor and are designed to provide maximum versatility in accordance with space size. Horizontally mounted double C-face brakes used in variable-torque and constant-torque-dependent commercial applications making them ideal for a range of use cases including: pumps, compressors, cranes, conveyor belts, fans, and more. Alternatively, vertically mounted double C-face brakes are well suited for industrial pump systems and low-inertia applications where space is more limited due to worker access requirements or restraints by larger, neighboring structural parts.

Easy Add-On to Existing Equipment

Disc brake couplers are versatile units that can be mounted to a C-face motor and reducer with simple two-wire connections to single phase or polyphase motors. As an easy add to existing equipment without having to replace the motor or other critical system components, double C-face brakes offer optimal torque levels with minimal maintenance or downtime.
