A ring NdFeB magnet housed with a flat steel cup with threaded bushing in the middle,the magnetic assemble is used as strong salvage magnet.The standard size range from 16mm to 75mm in diameter.
Steel housed NdFeB(neodymium) magnets are called neodymium pot/cup magnets, due to the magnetic solutions provided by steel housed neodymium magnets,they also known as neodymium clamping magnets, neodymium mounting magnets, and neodymium magnetic holders.
The the steel house not only protects the inside magnet, but also guides the magnetic line of force of the magnet to one side, which greatly enlarge the magnetic force. Covered with steel house,different designs for fastening become to be possible. For example,internal threaded bushing and external threaded mounting stud can be made on the top of steel house. Ø10mm NdFeB Flat Counterbore Pot Magnet
This one is flat type neodymium shallow pot/cup magnet with a threaded mounting hole in the center. The surface treatment choice includes zinc plating, nickel plating and plastic spraying, which have strong anti-corrosion performance.
These medium-sized neodymium pot magnets are made of a neodymium magnet encased in a stainless steel shell. The shell is completely sealed providing the maximum resistance to corrosion making these magnets ideal for applications in direct contact with liquid. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets can be fixed in place with the M8 bolt and washers included.
