Johnson Type CX DC Magnetic Disc Brakes

The Johnson Type CX DC Magnetic Disc Brakes are a versatile and robust solution for a wide range of industrial applications. Available in 11 distinct models, these foot-mounted brake units are constructed with a durable fabricated steel mechanism and come with separate enclosed control units suitable for both DC and AC supplies. They are ideal for use in mechanical handling equipment, cranes, winches, conveyors, and mills, providing reliable emergency stopping power, often installed on the flange of crane winding drums.

Engineered for high performance, the Johnson magnetic disc brakes offer a variety of options to meet specific operational needs. These include a self-adjusting device to compensate for brake lining wear, special materials and finishes, and limit switches to monitor release, set, or wear. For industries with high integrity requirements, such as the nuclear sector, these brakes are designed to meet stringent standards.

The magnetic actuator of the Johnson Type CX DC Magnetic Disc Brakes features a short stroke DC tractive type with an encapsulated coil and a screw-off release nut, with an optional switch. The all-fabricated steel construction ensures durability, while the resin encapsulated coil with Class F insulation provides reliable performance. The optional replaceable coil arrangement for the CX range, along with 100% continuous rating up to 40°C ambient, ensures these brakes are built to last. Additionally, the air gap is dust and drip protected by a neoprene gaiter, and the terminal box is enclosed in an IP55-rated enclosure for added protection.

For those seeking specific technical specifications, the brake models range from CU01 to CX135, with varying disc diameters, applied forces, effective face sizes, and weights to suit different applications. For instance, the CX90 model offers a disc diameter range of 960-1500 mm, an applied force of 225 kN, and a weight of 440 kg, making it suitable for heavy-duty applications. For discs outside the standard range, customers are encouraged to contact the support team for tailored solutions.
