Neodymium Pot Magnet with Threaded Stud Ø20 mm, Neoflux Pot Magnets,  Pot Magnets with Screw Socket,  Female Threaded Stud Pot Magnet, Interior Thread Bushing Pot Magnet China Manufacturer

Neodymium Pot Magnet with Threaded Stud Ø20 mm X 15 mm Part No.HS-ND20 by HSMAG Features :

Material: Housing steel and Magnetic core sintered neodymium magnet with internal thread .
Version: Housing, galvanized. Magnet, Ni coated or Zn coated
Note: Shallow pot magnets with Internal Threaded Stud. These magnets are pressed or glued into the receiving holes.
Hairline cracks in the magnetic material are unavoidable for technical reasons in the D=20 mm version. They do not impair the attracting function of the magnets in any way.
Temperature range: max. 80°C.

Holding Pot Magnet with Internal Threaded
A HSMAG magnets is sole provider of pot magnets that are internally threaded stud popularly known as Internal Threaded Stud. These magnets have a very large force, which can clamp down the ferromagnetic material because of its Ni or Zinc plated mild steel. Thus, allow a magnetic circuit with improved material, which can achieved with minimal sizes.
Pot Magnets with internal thread stud/Boss mounting have that thick steel backing with female thread section. With help of threads like M4 and M10 screw and a bolt, these magnets have a platform, which can hold the pot magnets with much efficient internal thread with Stud/Boss mounting on the place.

Stud Neodymium Pot Magnets Ø16 mm

Neodymium Pot Magnet with Threaded Stud Ø20 mm / The basic principle of the holding or pot magnet is to direct and concentrate the flux from both magnetic poles to one active face. This is usually achieved with steel pole pieces or a steel-backing cup.
The standard selection can be broken down into three material types and there is a great variety of systems available. The following data should act as a simple guide:
1) Rare Earth Samarium & Neodymium, pots and assemblies can offer up to eleven times the performance of a Ferrite system in a comparable size. Applications tend to be specialized engineering projects where performance and available space are key factors. Maximum operating temperatures are +60°C for the Neodymium and +150°C – +250°C for the Samarium depending on the design configuration.
2) Sintered Ferrite, this material offers a good performance from an inexpensive magnet, however, they tend to be bulky and are not always suitable where space is an important factor. The steel parts are plated & the Ferrite is inert thus corrosion is limited. Maximum operating temperature is +120 °C.
3) Cast AlNiCo, offers a better holding force than Ferrite systems and is the only pot magnet that can be heated to extreme temperatures. However, the high cost of the Cobalt content in the cast magnet makes the price prohibitive unless the application requires temperatures over +120°C up to a maximum of +500°C.
When considering your selection, please be aware of the following factors: The stated Kg Pull (holding/gripping force) is based on the magnets retaining force against a direct pull when offered to a clean ground mild steel surface with a minimum thickness of 8mm. Painted or un-ground surfaces will reduce this force, assemblies working in shear will support approximately 1/3 of the stated value.
