Wholesale Cup Magnets NdFeB Pot Magnet with Counterbore Hole

Neodymium Cylindrical Borehole Pot Magnets considers as ring magnet when these magnets have a pot magnet within. The spaces within an area of an inner diameter of these magnets have a screw and a bolt to fix it with any substance. This space occupies with Clearance hole in the ring magnet with a screw/bolt head. However, the sizes of the magnet occupy a diameter. With the help of these features, it helps the designer to verify the fixing of the screw and the bolt.

Product features:

• The strong cup magnets has Ni+Cu+Ni triple layer coated. The best coating available, it makes the neodymium magnets with countersunk holes surface smooth and flat, will not scratch the metal and has a rust-proof effect.

• These super strong neodymium magnets are protected in steel cups, which greatly increases the life of the magnets, and these perforated rare earth magnets come with screws for mounting on non-metallic materials, making them even more versatile.

• Heavy duty magnets can be used as locker magnets, magnets for fridge, calendar, map, kitchen, Billboard, Dry Erase Board, Tool storage in Home, storehouse, warehouse, warehouse, garage, workshop, office, classroom, school, science, funny decorative. Perfect size for easy Installation and use.

Advantages:

Neodymium Pot magnets have many advantages and can be supplied with a tapped hole, a countersunk hole, a counter-bored hole, a threaded stud or a threaded collar all for convenient mounting. They can also be supplied with hooks and eyebolt attachments, ideal for hanging a variety of items.

· best choice for using on steel surfaces.

· unlike permanent magnets, mounting magnets,pot magnets will not break or crack since they are protected by their metal body.

· Easy to install.

· best choice for hanging.

· Cost-effective

Size:

Pot Magnet with Through Hole Mounting is available in sizes from 8mm to 150mm diameter with pull forces ranging from 0.5kg up to 500kg. The holes could take M3,M4 M5, M6, M8 and M10 threads. The inner diameter of the ring magnet is much larger than the hole in the steel casing allowing the head of the bolt or screw to easily fit in place.

Applications

Neodymium Magnet Pot Powerful Rare Earth Pot Magnets: Made of strong rare earth Neodymium Magnet, uniquely design to have magnet sits inside a hard steel housing to provides excellent mechanical properties and durability.

These super magnets could be used for assembly at Home, Business and Schools, Science Projects, Workshop, Office for art projects, craft etc.

FAQ:

Q1. What's a pot magnet?

A1. Pot magnets are special magnets which, especially the bigger ones, are used in the industry as industrial magnets. The magnetic core of pot magnets is made of neodymium and is sunk in a steel pot in order to intensify the adhesive force of the magnet. That is why they are called "pot" magnets.

Q2. Are pot magnets stronger?

A2. Compared with single neodymium countersunk magnet, pot magnet has more advantages: 1. More Magnetic Strength with Small Size: the steel housing concentrates magnetic force on one side and increases the holding power dramatically.

Q3. Why are pot magnets stronger?

A3. The steel shell on a pot magnet means that it can hold a greater amount of ferromagnetic material. This is because the steel pot causes the magnetic force to be contained within the shell on the ferromagnetic surface, making the magnetic pull stronger.

Q4. What are pot magnets used for?

A4. High in magnetic strength for their small size, pot magnets are ideal for all types of applications where high strength magnets are required. They are often used for heavy duty holding, mounting, and fixing purposes in workstations, classrooms, offices, warehouses, for pop displays, as retrieval magnets and more.

Q5. What is shallow pot magnet?

A5. The countersunk mounting pot magnet is also known as a shallow pot magnet (a term often used with ferrite material as the inner magnet but other magnet materials are used). The countersunk mounting pot magnet / shallow pot magnet is a ferromagnetic steel cup into which is inserted a countersunk ring magnet.
