Does your company have access to magnetic sand for electric brakes?
The powder (sand) used in electromagnetic powder brakes (EMP) and clutches may vary in grain size and quantity from one brake/clutch manufacturer to another. Over a period of time the powder will lose its effectiveness as it becomes contaminated with wear debris from the hard chrome surfaces inside the unit, this will display itself a “slipping”. The powder can be replaced but this will become more frequent as the hard chrome surfaces deteriorate exposing the soft housing underneath until the unit needs to be replaced. CGB Precision Products can offer replacement powder and repair kits (bearings and seals) for specific brakes and clutches manufactured by Merobel France.
