Buy Pot Magnets with Internal Threaded Mounting online with Bunting – eMagnets™
The Pot Magnet with Internal Threaded Mounting can be attached to other items by using screws or bolts with M3, M4, M5, M6 and M8 threads. They come in Alnico, NdFeB, and SmCo formats and mainly have chrome, zinc, nickel or red paint-coated mild steel casings.
The Alnico Pot Magnet with Internal Threaded Mounting is rated for use up to +220 deg C. The NdFeB Pot Magnet with Internal Threaded Mounting is rated for use up to +80 deg C. The SmCo Pot Magnet with Internal Threaded Mounting is suitable for very high-temperature applications.
Products E1038 and E1039 are ideal for high-temperature corrosion-resistant applications. Unlike Neodymium magnets, the Samarium Cobalt magnets do not corrode when in damp environments (salt spray, high humidity). To prevent corrosion of the Pot Magnet steel casing, the steelwork of the SmCo Extreme Pot Magnet is upgraded to ferritic stainless steel (SS 430 grade). The supplied hook is upgraded to stainless steel (SS 304 grade) to aid with corrosion resistance. The adhesive in the SmCo Extreme Pot Magnet is also improved to cope with temperatures of up to +300 degrees C.
For use in dry, room temperature conditions the SmCo Extreme Pot Magnets are not quite as strong as the similarly sized NdFeB Pot Magnets. But at temperatures above +80 degrees C, the NdFeB Pot Magnets start to have reduced output as the heat starts to demagnetise them. The SmCo Pot Magnets will operate with little drop in performance up to +80 deg C and can be used at much higher temperatures. The SmCo Extreme Pot Magnet has been designed to perform at temperatures up to +300 degrees C. It may be possible to use SmCo Extreme Pot Magnets at up to +350 degrees C but the adhesive may start to fail (it is rated to +300 deg C).
For use at cold temperatures, the adhesive becomes brittle and risks failing (although may recover when warmed up). The SmCo Extreme Pot Magnet can be used at cold temperatures when taking this into account (Pot Magnets containing ferrite magnets are not suitable for very cold applications as the cold starts to demagnetise them; this is a feature linked only with ferrite magnets). Ignoring adhesive effects, it is possible to use the SmCo Extreme Pot Magnet to hold onto ferromagnetic structures at very low temperatures (e.g. to -100 degrees C) although suitability for use towards cryogenic temperatures (i.e. towards -273 degrees C), for which Samarium Cobalt magnets on their own are definitely suitable, is theoretically possible with a SmCo Extreme Pot Magnet but is, as yet, untested.
The Pot Magnet with Internal Threaded Mounting range offers maximum clamping forces from 0.8kg up to 50kg.
We have an extended range of Pot Magnet with Internal Threaded Mounting available – please contact us for the brochure (we may require a minimum order quantity). It is also possible for us to produce bespoke Pot Magnets with Internal Threaded Mounting but a minimum order quantity may be required (the minimum quantity depends on the size, shape and performance required).
