Counterbore Ferrite Pot Magnets

Unlike the ferrite channel magnet, these ring shaped ferrite magnets are glued in shallow iron cup with holes in the center. The iron cup acts as a fixed base and also enhances the magnetic force of the ferrite magnet. This kind of magnetic assemblies are called counterbore ferrite (ceramic) pot magnet in the industry. The popular sizes of ferrite (ceramic) pot magnets with cylindrical counterbore holes are 50mm, 57mm, 63mm, 80mm and 100mm. There are technical specification of the steel covered ferrite ring magnets in the following table.

Characteristics Of Counterbore Ferrite Pot Magnets

  • The hole on the iron shell is smaller than that of the magnet, providing a fixed position for the flat head screw.

  • Nickel or zinc is plated on the iron shell of the counterbore ferrite pot magnets.

  • Anisotropic ferrite magnets are used to the counterbore ferrite pot magnets.
