Good magnetic properties, affordably priced
Ferrite pot magnets - or ceramic pot magnets - are fitted with a steel pot that provides shielding of the magnetic field. Ferrite pot magnets require only a minimal installation height. This provides constructive advantages.
When does loss of magnetic strength occur?
Ferrite pot magnets have an operating temperature of up to 200 °C. When heated to this temperature, the magnet loses 30 to 40% of its magnetic force. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.
Corrosion resistant and screwable at a high torque
Ferrite pot magnets do not corrode and are very suitable for outdoor use.
The pot magnets with cylinder hole are suitable for extra tightening. There is no force on the pot magnet itself. This is not a part of the screw connection. Mounting is easy with a cylinder head bolt.
