The BCH S-72 is a Type S AC Solenoid Operated Brake designed for braking and holding applications in electrically driven industrial machinery. It features a 180 mm (7 inch) brake wheel diameter and a maximum braking torque of 102 Nm (75 lb-ft). BCH specifies the S-72 for intermittent-duty operation.
The BCH Type S brake range uses an electrically released and spring-applied operating principle, providing a fail-safe braking arrangement. When the solenoid is energized, the brake is released; when the electrical supply is removed, the spring-applied mechanism engages the brake. This makes the Type S design suitable for applications where dependable stopping and holding are important.
The S-72 is part of the 7-inch Type S brake family. BCH lists the S-71 at 68 Nm for continuous duty and the S-72 at 102 Nm for intermittent duty, with the same approximately 180 mm wheel diameter. The standard compatible brake drum is AC50D7.
The brake is suitable for appropriately designed applications such as conveyors, hoisting equipment, elevators, escalators, machine tools, printing presses, small cranes, overhead doors and other electrically driven machinery. For frequent stopping or heavy inertial loads, the required stopping performance should be evaluated using the load inertia, shaft speed and stopping frequency.
The BCH S-72 AC Solenoid Brake can be considered for:
The BCH S-72 provides a practical braking solution for machinery requiring up to 102 Nm of maximum braking torque with an approximately 180 mm brake wheel. Its intermittent-duty specification makes it appropriate for applications where the brake does not need to operate continuously within the same duty profile as the continuous-duty S-71.
The spring-applied and electrically released design provides fail-safe braking operation. This operating principle can help ensure the brake is applied when the electrical release supply is removed, making it suitable for equipment where controlled stopping and holding are important.
The 102 Nm torque capacity provides a defined braking capability for compatible loads. Brake selection should not be based on torque alone; factors such as shaft speed, load inertia, stopping frequency and required deceleration time should also be evaluated.
The 180 mm / 7-inch wheel size places the S-72 within the BCH 7-inch brake family. The corresponding AC50D7 brake drum is listed as the standard drum for S-71/S-72 applications.
The brake's intermittent-duty construction can be useful in applications where braking occurs periodically rather than continuously. For frequent stopping or high-inertia loads, BCH recommends providing complete application details for proper engineering evaluation.
BCH provides multiple standard coil-voltage choices for Type S brakes. The applicable voltage should be selected according to the brake configuration and available control supply.
The BCH Type S AC Solenoid Brake is designed for long life, easy installation and minimum maintenance, making the S-72 suitable for OEM machinery manufacturers, industrial maintenance teams, panel builders and plant engineering departments.
