This is a Samarium Cobalt bi-pole deep pot magnet (also known as a twin-pole pot magnet) which can be used in high temperature clamping applications. It is called a 'Deep Pot' because height is greater than the diameter.

Samarium cobalt is a rare earth material which is used for higher temperature applications and this particular pot magnet will operate in temperatures up to 200°C. It has very tight manufacturing tolerances and the brass shell has been ground to an H9 tolerance allowing for press fitting into precision milled holes. The Samarium Cobalt is embedded in the centre of the pot magnet with two mild steel poles, one on either side of the magnet. These mild steels are visible on the bottom of the pot, one is north and the other is south. This arrangements gives flux concentration and a higher pull-surface area ratio. The steel poles also take the brunt of mechanical forces during clamping and protecting the Samarium Cobalt magnet inside the pot.


The most common uses are in fixture jigs, assembly designs, work holding and positioning applications, clamping applications including high temperatures and all applications where high hold forces are required during clamping.
