There are generally two types, one is low-speed, bonded with AB glue; the other is high-speed bonded with AB glue and then fixed with a stainless steel sleeve; many only use AB glue to add a layer on the outside Plastic, so that one can be fixed, and one can prevent iron things from being adsorbed to the surface of the magnetic steel, which is difficult to remove, or the electrophoretic layer on the surface of the magnetic steel is destroyed when removing! Generally, AB is used for those below 3000RPM and a diameter of 55 or less. Adhesive bonding is no big problem!
