Magnet Brake (TB-AN Type)
This frictional powerless brake, manufactured according to the regulation JEM 1240, is AC controlled DC magnetic brake, which satisfies the use of hoisting of cranes, roller tables, press accessory machines, belt conveyors, etc. in mini mill factories.
Furthermore, this DC magnetic brake has specific characteristics such as short working time, shockless, high frequent use quick stop of big capacity motor, good holding power in holding state and other hard working conditions.

(1) No lubrication of rotating frictional areas 

    The brake is adopted with oil-less dry metal to the frictional areas (Conjunction Pins) not necessary to oil maintenance.


(2) Reduction of shocks

    Shockless to the motor shaft and brake drum by means of sealing cover that air dampers the gap between magnetic plates.

(3) Small and light

    Main structure is steel casting, good look, small and light.

(4) High reliability and pragmatic

    Suitable to high frequent use(600 times/Hr), continuous operation, hard working conditions.


(5) Easy to disassemble / assemble

    All the conjunctions areas are connected bolts and pins, and when replacing the brake coil, only the coil can be separated 

      and assembled.
