Notes to avoid the demagnetization of SKF bearing rings

To make the SKF bearings demagnetization amplitude as large as possible and the amplitude decay as slowly as possible in the demagnetization machine, you should follow the notes

1.       The products can not be piled up together when demagnetization.Otherwise, the outer products will have shielding effect on the middles and decrease the demagnetization amplitude.

2.       The axis of the products should be made perpendicular to the demagnetization drive's magnetic line.As bearing products like a ring conductors, if its axis parallel to the magnetic line, equivalent to a short-circuit ring in the demagnetization drive, The magnetic field generated by this short-circuit ring is just opposite with demagnetizations to reduce the amplitude.  

3.       Products leave the demagnetization machine should be as slow as possible.The magnetic field decays when products leave the demagnetization machine. Leaving fasterdecaying faster.
