Overview - Samarium Cobalt Deep Pot Magnet

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 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.

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.

"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."

Adrian Seeley, Production Supervisor at AB MAURI UK & Ireland

"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"

Maintenance Manager at EXL Tube (Steel Ventures)

"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."

John Smith, MMTCI

"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."

Facilities Manager, Milacron Machines (Sub-Contract Machining)

"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."

Pat Richards, Chief Engineer at Simpsons Malt

“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”

Kenneth McRae, Principle Engineer at Vallourec

"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."

Justin Lawler Ph.D. MBA, Chief Technology Officer at Qualflow Systems Ltd

"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"

John Crossley, NDT Technology Lead at the Nuclear AMRC

"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
