Other proposals

This type of holder has a integrated threaded stud (screw), making it ideal for mounting in through holes. Mounting consists of inserting the screw into the hole and securing with a nut (e.g., wing nut). They are commonly used in machine building, exhibition stands, lighting, and advertising.
Too strong tightening with a wrench can cause the stud to rotate in the cup or strip the thread. Do not use the magnet as a structural bolt transferring huge mechanical loads in shear. The magnet itself is protected by a steel cup and is very resistant to impact.
Standard neodymium holders are adapted to work in temperatures up to 80°C. If you need resistance to higher temperatures, ask about special versions (H, SH). Avoid mounting directly on hot engine or machine components.
We use standardized threads that fit typical nuts available in every store. Exact screw dimensions can be found in the product technical table. The thread is made of galvanized steel, ensuring corrosion resistance.
Thanks to shielding the sides and top, all magnet power is directed downwards, giving higher capacity than a bare magnet. However, such a system works point-wise and requires direct contact with metal.

Pros as well as cons of rare earth magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
  • Neodymium magnets are extremely resistant to loss of magnetic properties caused by external magnetic fields,
  • By using a shiny coating of nickel, the element acquires an proper look,
  • Magnets have extremely high magnetic induction on the active area,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • In view of the potential of precise molding and adaptation to individualized needs, magnetic components can be manufactured in a broad palette of geometric configurations, which expands the range of possible applications,
  • Universal use in modern industrial fields – they serve a role in hard drives, drive modules, medical devices, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices

Disadvantages

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
  • Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

Holding force of 140.00 kg is a measurement result conducted under specific, ideal conditions:
  • on a base made of structural steel, effectively closing the magnetic field
  • whose thickness equals approx. 10 mm
  • characterized by smoothness
  • without the slightest insulating layer between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • in temp. approx. 20°C

What influences lifting capacity in practice

In real-world applications, the actual lifting capacity depends on several key aspects, ranked from crucial:
  • Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
  • Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Warnings
Keep away from computers

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Crushing force

Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.

Product not for children

Always store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.

Immense force

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Fragile material

NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets will cause them breaking into small pieces.

Do not drill into magnets

Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.

Nickel allergy

A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause dermatitis. It is best to wear protective gloves.

Life threat

Individuals with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.

Demagnetization risk

Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Impact on smartphones

GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
