B-7V & B-20V Brakes The B-7V and B-20V are designed for those applications where the axis of the shaft may not be horizontal. These brakes will operate with the axis vertical, horizontal, or at any angle you require. Instead of the cylindrical design of other magnetic particle brakes, these units have a disk shaped rotor. The space between the rotor and two sides is filled with the magnetic particles so the unit can be operated in any orientation. Applications include tensioning of film rolls on vertical shafts, packaging machines, and machine tools. B-20V Magnetic Particle Clutches & Brakes Typical Heat Dissipation Capacity Typical Torque vs. Current (90 VDC coil) Curves show heat dissipation capability of models under continuous duty conditions. No "de-rating" or "service" factors need to be applied. Do not size a brake at a torque rating over its rated torque. CAUTION: This product contains rotating parts which could cause injury. At the time of installation, appropriate protective guards should be installed by the user according to the use of this product. 128 Magnetic Particle Clutches & Brakes
