Johnson MB Series Thruster Disc Brakes

The Johnson MB Series Thruster Disc Brakes are a versatile and robust solution for a wide range of industrial applications. Available in five distinct models, these compact brake units are engineered with a fabricated steel mechanism and feature major pivots that are non-ferrous bushed. The high-temperature resistant friction linings ensure durability and reliability, while the standard Eltma Elhy EB series IP56 thruster provides a secure and enclosed operation. Ideal for use in mechanical handling equipment, cranes, winches, stacker reclaimers, and conveyors, these brakes are designed to meet the demands of heavy-duty environments.

Each model in the Johnson MB Series offers a variety of options to enhance performance and adaptability. Users can choose from features such as a self-adjusting mechanism, a mechanical release lever, and limit switches to monitor release, set, or wear. For those requiring precise control, electronic modulated torque can be managed via a remote pedal. Additionally, the brakes can be customized with special materials, tests, and finishes to meet high integrity requirements.

The thruster data for the Johnson MB Series is impressive, with the standard EB Series utilizing transformer oil BS148, typically Shell diala ‘B’. The brakes boast approximate operating times of 0.1 seconds for release and 0.25 to 0.5 seconds for setting, depending on size and brake spring load. Optional features include high-temperature viton seals, internal preset hydraulic delay valves, a dust-protecting hood, and an internal return c-spring. For those operating in hazardous environments, an explosion-proof design is available, compliant with EExd Group I and II standards.

For added flexibility, alternative thrusters such as Johnson/Eldro/Elhy/Elco to DIN 15430, Johnson DC Custom, and KT/TKF types can be supplied. Flame-proof options are also available, ensuring that the Johnson MB Series Thruster Disc Brakes can be tailored to meet the specific needs of any industrial application. With a range of models offering varying disc diameters, applied forces, and weights, these brakes provide a comprehensive solution for any braking requirement.
