SmCo Deep Pot Magnet

The Samarium Cobalt (SmCo) bi-pole deep pot is used in higher temperature clamping applications. Bi-pole pot magnet is also known as a twin-pole pot magnet. The deep pot name is linked to the design style (usually taller pot magnets with magnetism deeper into the clamped ferromagnetic surfaces). The Samarium Cobalt material allows this powerful rare earth pot magnet to be used at temperatures up to +200 degrees Celsius (+392 Fahrenheit).

Having a precision ground H6 tolerance on its brass retaining shell / cup allows the magnet to be inserted into precision milled holes by press fitting. The SmCo magnet material is embedded within the pot magnet structure – two ground mild steel poles are visible (one is a North face; the other a South face), allowing flux concentration to give a high pull to surface area ratio. The steel poles also allow the Samarium Cobalt deep pot bi-pole magnet design to take any mechanical forces during the clamping process, protecting the SmCo magnet within the deep pot.
