New Higher Torque Electromagnetic Particle Brakes


Ogura has developed two new models of the OPB series of magnetic particle brakes. The two new models, OPB 120N and OPB 250N are rated at 110 in. lbs. and 220 in lbs. respectively. The largest previous model in the OPB series was rated at 70 in. lbs.

Heat dissipation of the 120N is 80 watts and heat dissipation of the 250N is 100 watts but both brakes will have an optional mounted fan to increase heat dissipation to 200 watts and 240 watts respectively. Although the brakes are mainly used for tension control of foil, film, wire and paper there are many other industrial applications where soft stops can be of benefit. Since output torque is almost directly proportional to input voltage/current, torque can be controlled very quickly and accurately. An example being a conveyor system conveying a delicate or sensitive product would require a controlled stop to avoid damage. The new brakes series are designed to be less costly than the old PB series and will be more readily available.

Ogura has been producing clutches and brakes since 1938. Over that time, we have developed over 5,000 different models of clutches and brakes. Although Ogura primarily produces electromagnetic clutches and brakes, we also produce magnet particle, mechanical, pneumatic, hydraulic and a variety of specialty products. Ogura is the world's largest manufacturer of electromagnetic clutches and brakes. Current manufacturing capacity is over 30 million units per year. To provide localized support, we have fourteen manufacturing plants spread throughout the world in Asia, The Americas, and Europe. All manufacturing facilities are ISO recognized and conform to the ISO 9001;2008, ISO 140001, and ISO/TS 16949.
