The most common permanent magnets assemblies that magnet housed with round steel shell are pot (cup) magnets, they are results of the development of magnets application, and widely used in magnetic holding,magnetic mounting.All types permanent magnetic material can be used to make pot (cup) magnets. Besides of protecting the inner magnets, the steel cups can transfer the magnetic line and make it into a magnetic circle. By this, the steel cup provides the magnets with more magnetic strength. Then the magnetic strength of whole magnet assembly is much more than equivalent round magnets. Rare earth neodymium is the best material to make the strongest pot(holding,mounting) magnets.
According to needs, the steel shell of pot(cup) magnets can be made into different types, Meank magnetics often make the following types of strong holding & mounting magnets:
Type-A： Neodymium pot(holding, mounting) magnets with a countersunk (counterbore) mounting hole, a countersunk NdFeB magnet housed in a steel cup with a hole in the center.The hole let the magnets easy to be screwed on.Countersunk pot magnet offer a magnetic base for magnet fishing.
Type-B：Flat neodymium shallow pot magnets with a cylindrical mounting hole, which composed of ring neodymium magnets and steel cups with a hole.This design makes it easy to be mounted.
Type-C： Strong mounting magnet composed of a disc neodymium magnet and steel cup that with an external(male) threaded stud. Which is called externally(male) thread neodymium pot magnets and neodymium pot magnets with external thread stud, the external thread magnets are strong enough for holding.
Type-D： Internal(female) thread neodymium pot(cup) magnets,they are composed of disc neodymium magnets and steel cups with internal threaded bushing which make them easy to screw hooks or bolts. Female thread cup magnet is magnetic base for hook magnet.
Type-E： Hook magnets or magnetic hooks. The disc neodymium magnet are affixed into a steel cup with an female threaded socket, The hook can be removed and replaced with eyelet and bolt. Strong neodymium magnetic hooks are used for heavy duty hanging.
Type-U： The steel shell is flat and without hole and threaded stem,which called flat neodymium shallow pot(cup) magnet, which used as strong holding&clamping magnets
Type-H： Flat neodymium pot(cup) magnet with a threaded hole in the center,it can be used for mounting and fishing.
Our ndfeb pot magnets are used to mount lighting, exhibition equipment and other devices.
Our neodymium pot (cup) magnets can be used to hold and clamp the ceiling, signs, banners.
Our neodymium cup magnets can be used for heavy duty hanging.
Countersunk pot magnets are magnets with mounting holes, they are mounted with countersunk head screw.You can mount a countersunk pot magnet onto wood door for holding.
External threaded pot magnets are mounted with nut, make a hole in the panel to be installed, the external screw stud passes through the hole, and screw on the nut on the other side of the panel.
Above types are just standard types of holding pot magnets we make, we can also make other types based on customers' designs. Our standard types of holding pot magnets for sale are made from neodymium strong magnets. All our neodymium holding pot magnets for sale have good market performance. Our company, a notable pot magnet supplier, a powerful pot magnets factory, will ensure our customers buy neodymium pot magnets that meet their needs.
To meet clients' needs on actual application conditions and cost control, we provide a different magnetic material choice on the magnets used for each type ndfeb pot magnet. And also have wide range of size for choosing according to the need of holding force. If clients need very powerful magnetic strength and want to save cost, the ferrite pot magnets or ceramic pot magnets are perfect. If clients want very strong magnetic power, they can buy our neodymium pot magnets for sale. If clients used the pot magnets under the condition of higher temperature, then SmCo pot magnets can be used. All in all, there must be one type suit for you.
Neodymium material makes the best strong pot magnets while ferrite material make the best rust-resistant pot magnets.
Choose countersunk pot magnet for magnetic holding on walls.
Choose the pot magnet with external threaded stud for magnetic holding on plate.
Choose the pot magnet with threaded socket for magnetic lifting.
A pot magnet usually work with steel hook or rings.
