Detail Description


Sunrise Low MOQ Single shaft magnetic powder brakes for printing machine


PFB Attention for using magnetic powder brake:


1, Install it with correct mounting method (make high-speed rotation side as the input side) to use the magnetic powder clutch. If the mechanical structure of output and input shafts have to be installation reversely, make sure to use the under 1000R/MIN. If the output shaft and input shaft be installed reversely, which will make the machine idle for a long time,  the magnetic powder clutch will greatly shorten the life by mixing magnetic powder. 

2, Note the moisture. If the magnetic is damp, then performance will become unstable, so be careful do not to let the oil or water get into the housing. Especially when installed in the gear box, oil penetrated the internal branch of the housing through the shaft, so please seal it with film completely.

3, Note the surface temperature. Caused by continuous operation, the maximum temperature of the surface is below 90 degree when running more, than the value and durability will be greatly reduced. Make sure to limit the temperature will not above90 degree, make sure to keep the use of sliding within allowed work range.
