This ferrite pot magnet has a diameter of 90mm, a height of 12mm and a pull force of 30kg. It has a countersunk magnet bore and a 4.6mm pot bore.
Our These large Ferrite Pot magnets have a mild steel cap that covers a ferrite ring magnet with a convenient countersunk central hole. This hole allows them to be attached to non-metallic surfaces and also protects the brittle Ferrite material from being damaged. The casing over the magnet also increases the pull force to the uncapped magnetic surface which makes them a cost-effective alternative to Rare Earth magnets and ideal for use in holding or securing applications.
CAUTION: Do not overtighten attachment screws as this can potentially cause the magnet to become damaged or cracked.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
