Pressure brakes have the advantages of simple structure, wide adaptability, low noise, and reliable braking, and are widely used in various mechanical transmission devices. They are an ideal actuator in industrial modernization. The automation of production technology requires ultra-thin power-off brakes (safety brakes) to meet the needs of various machinery such as robots and motors for different purposes with their excellent characteristics.

Pressure brakes are divided into short stroke block brakes and long stroke block brakes according to the length of the control device stroke. The magnet of the short stroke block brake is directly installed on the brake arm. During operation, the moving iron core rotates around the pin shaft to achieve the release of the brake; When the magnet loses power, it relies on the main spring to tightly close. This type of brake has a compact structure, with fast closing and releasing actions, but with a large impact force. Long travel block brakes can generate a large release force through the brake lever system, but the braking action is smooth and suitable for various sizes of deceleration equipment.
