Neodymium Block Magnet - 20mm x 12mm x 5mm | Countersunk 5mm-7mm hole

Neodymium Block Magnet Product Description:

These Rare Earth Neodymium Block Magnets, or Bar Magnets, have a centered countersunk hole designed for mounting on a surface. Strong Neodymium magnetic material allows for an impressive pull force of approximately 5.9kg. They are super strong considering their small size of 20mm x 12mm x 5mm. This permanent magnet is axially magnetised and the countersunk hole allows for the magnet to be installed on most surfaces.

AMF Magnetics uses high-quality Rare Earth Magnets for maximum strength. AMF offers bulk discounts for this product.


Uses for our Rare Earth Block Magnet with Countersunk Hole:

Many magnets, or magnetic devices, act as torque limiters. A torque limiter is a device that protects mechanical equipment from damage from any excessive mechanical force. Many of these devices use strong neodymium blocks because of their size to strength ratio. Often used in propeller assemblies or liquid pumps to regulate force through a watertight barrier. This method of transfer of force avoids the need for rubber seals which can perish over time and fatigue easily.

This bar magnet is also used as a precaution on jewellery like necklaces and bracelets or earrings. Magnetic clasps protect both the wearer and the precious material in the event of excessive force by uncoupling. This allows for individual components to simply be re-attached by their owners.

Painting support using magnets

The rare earth magnets are meeting our expectations with providing support for my paintings. They enable me to set up time efficient displays with keeping my paintings secure. The process of purchasing was expedient and easy. Thanks

Strong magnets best invention since the deep plate.

Life is about what you see.

So hang is when u can

Do not hide it

Hang it on a magnet is cheaper than looking

And finding after you bought a new thing.
