These are magnets in the shape of a rod in a brass or steel sleeve, ideal for embedding in deep sockets. Thanks to side shielding, they do not "catch" the walls of the mounting hole, which facilitates installation.
These holders usually have an internal thread (blind or through) on the back wall. Thanks to the long body, the magnet is stable in the hole and does not tilt.
The thick, steel or brass housing (sleeve) effectively screens the magnetic field on the sides of the holder. This is a key feature when mounting in steel sockets so the magnet doesn't "stick" to the hole walls during insertion.
The neodymium magnet is deeply embedded (glued) in a solid block of steel or brass, making it very resistant. The risk of magnet cracking with normal use is minimal as it is shielded.
We recommend making the mounting hole with slight clearance and using glue for certainty. It is an industrial product, not a precise machine element, although the execution is careful.

Pros as well as cons of rare earth magnets.

Advantages

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
  • Neodymium magnets prove to be exceptionally resistant to demagnetization caused by magnetic disturbances,
  • Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
  • Magnetic induction on the top side of the magnet is impressive,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to flexibility in designing and the capacity to modify to specific needs,
  • Universal use in advanced technology sectors – they serve a role in mass storage devices, drive modules, medical devices, as well as technologically advanced constructions.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets: tips and applications.
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic holder.
  • Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

The force parameter is a measurement result performed under specific, ideal conditions:
  • with the use of a sheet made of special test steel, ensuring full magnetic saturation
  • whose thickness is min. 10 mm
  • with an polished contact surface
  • without the slightest insulating layer between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in temp. approx. 20°C

What influences lifting capacity in practice

Effective lifting capacity is affected by working environment parameters, mainly (from priority):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
  • Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Warnings
Caution required

Handle with care. Rare earth magnets act from a distance and snap with massive power, often quicker than you can react.

Keep away from children

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.

Machining danger

Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Danger to pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Beware of splinters

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Metal Allergy

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose coated magnets.

Phone sensors

GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Crushing risk

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Maximum temperature

Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Safe distance

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
