SKU: GM17440
Stock: 16
Diameter (D): 50 mm
Height: 10 mm
Material housing: Galvanized steel
Compact magnet systems with a steel shell and a cylinder hole for easy mounting. These pot magnets are screwable at a high torque while the magnet remains unloaded. Thanks to the shell of these magnet systems, the magnetic field strength increases and the pot magnets are more resistant to corrosion or chemicals. Pot magnets have a single attracting surface. This precludes dispersion of the magnetic field.Pot magnets with cylinder hole are available in various sizes and grades such as neodymium and ferrite.

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron (NdFeB), which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface is covered with a protective coating to prevent corrosion. The cylinder hole makes the magnet system screwable with a high torque.

Operating temperature

When does loss of magnetic strength occur?

Neodymium cylindrical and flat pot magnets have a maximum operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% 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.
 

Important to know

Screwable at a high torque

These 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.
