Samarium Cobalt deep pot magnets

Details of the Samarium Cobalt bi-pole deep pot magnets

The Samarium Cobalt (SmCo) bi-pole deep pot is used in higher temperature clamping applications. The 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 it 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.

Applications of the Samarium Cobalt deep pot magnets

This Samarium Cobalt deep pot design is often used in fixturing jigs, assembly designs, work-holding positioning applications, high temperature clamping applications and applications where high hold forces exist alongside larger mechanical knocks during the clamping.

The Samarium Cobalt (SmCo) bi-pole pot magnet comes in diameters varying from 6mm through to 32mm and height varying from 20mm to 40mm. The Samarium Cobalt (SmCo) bi-pole deep pot magnets have pull forces varying from 0.8kg (8N) up to 60kg (600N) depending on the application.

It is possible for us to produce Samarium Cobalt (SmCo) bi-pole pot magnets in different sizes with different pull force values – please contact us for more information if you require such a customised Samarium Cobalt (SmCo) twin-pole pot magnet.
