These are magnets in the shape of a rod in a brass or steel sleeve, ideal for embedding in deep sockets. They are used in positioning elements, injection molds, dies, and automation.
It can also be glued or pressed (maintaining tolerance) into a prepared hole. The mounting thread allows for stable and secure fixing in a machine or jig.
The construction causes the magnetic flux to short-circuit inside, making the sides practically non-magnetic. It enables precise point action without side interference.
It is one of the most durable types of holders, resistant to crushing. Thanks to the solid build, the holder withstands repeated impacts and shocks during work cycles.
These holders are produced with standard tolerance for industrial magnets (usually ±0.1 mm or h6). If high precision is required, measure the specific batch with a caliper before machining sockets.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
  • Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • Magnets are distinguished by very high magnetic induction on the active area,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to flexibility in designing and the capacity to modify to specific needs,
  • Huge importance in electronics industry – they find application in computer drives, electric motors, precision medical tools, as well as industrial machines.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Limited possibility of creating threads in the magnet and complex shapes - recommended is cover - mounting mechanism.
  • Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can complicate diagnosis medical when they are in the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

The lifting capacity listed is a theoretical maximum value conducted under standard conditions:
  • with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
  • whose thickness equals approx. 10 mm
  • with a surface perfectly flat
  • without the slightest clearance between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • at room temperature

Practical lifting capacity: influencing factors

In practice, the actual holding force results from a number of factors, listed from the most important:
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
  • Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Precautions when working with NdFeB magnets
ICD Warning

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Risk of cracking

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Electronic hazard

Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Heat sensitivity

Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.

Mechanical processing

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Allergy Warning

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact or choose versions in plastic housing.

Pinching danger

Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.

GPS Danger

A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to avoid damaging the sensors.

Handling rules

Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and respect their power.

Product not for children

Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.
