GME, where you can find awesome quality, but also great service!
Cup Magnets are strong neodymium magnets that are set inside a steel cup or channel.
Most of cup magnets come in round shapes, but we also offer a few Rectangular Mounting Magnets.
These are powerful neodymium magnets housed inside of a stainless steel cup.
The cup protects the magnet and also increases the magnets power by redirecting one polarity towards the other side.
Attached to the cup there is a threaded stud that will work perfectly with a standard nut or threaded hole.
Cup magnets include countersunk holes or
threaded features that allow for mounting with standard hardware (nuts
and bolts), as well as various hooks.
Cup magnets are intended to attract to a steel (or other ferromagnetic) surface.
Awesome advantages: threaded features that allow for mounting with standard hardware (nuts
and bolts), as well as various hooks.
Cup magnets are intended to attract to a steel (or other ferromagnetic) surface.
More Magnetic Strength: 3-5 times of common neodymium magnet.
With the steel cup of a mounting magnet, the steel structure redirects
the magnetic field from the back-side of the magnet, turning it into
more useful holding strength.
The Magnetic force is made stronger because the south pole is redirected to face north.
Durability: Our Mounting Magnets are constructed so that the surface of the magnet is set very slightly below the surface of the steel cup.
When it hits a steel surface, the steel cup takes the brunt of most impacts.

Introduction of Great Magtech:
Advantages of GME cup magnets
1. High Grade / High performance of cup magnets: GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
2. High Consistency of cup magnetss:
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67.
The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
3. High Working Temperature of cup magnets:
GME magnets can satisfy the working temperature requirements with excellent temperature resistance.
The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.
4. Low Weight loss of cup magnets:
GME super-high magnets have a long lifetime with the following specifications; PCT: 130C，humidity 100%，
vapor pressure 2.7bar, 20days，average low weight loss <2 mg/cm².
5. High anti-corrosion of cup magnetss:
coating Nickel-Copper-Epoxy is typically more than 1000 hours.

Be careful – they’re super strong unexpected!
As always, you can't be more careful when handling strong neodymium magnets. Handle these cup magnet with care, especially the larger ones.
You don’t want to
pinch your finger between magnets that can exert hundreds of pounds of
force!
