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.

Mounting is done by screwing with a bolt from the back of the device or machine. It is a precise, durable solution enabling depth adjustment.

The thick, steel or brass housing (sleeve) effectively screens the magnetic field on the sides of the holder. It increases attraction force in the magnet axis and facilitates assembly in ferromagnetic blocks.

The steel housing provides excellent mechanical protection for the brittle magnet against impacts. 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). It is an industrial product, not a precise machine element, although the execution is careful.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:

They retain magnetic properties for nearly ten years – the loss is just ~1% (based on simulations),
Magnets effectively resist against loss of magnetization caused by external fields,
By applying a smooth layer of gold, the element has an elegant look,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to modularity in shaping and the capacity to adapt to complex applications,
Wide application in electronics industry – they are utilized in mass storage devices, motor assemblies, diagnostic systems, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases 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 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complex forms in magnets, we recommend using cover - magnetic mechanism.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

Information about lifting capacity was determined for optimal configuration, assuming:

using a base made of mild steel, serving as a ideal flux conductor
with a cross-section of at least 10 mm
with an ground touching surface
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in stable room temperature

Impact of factors on magnetic holding capacity in practice

In real-world applications, the actual lifting capacity results from many variables, ranked from crucial:

Distance (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Angle of force application – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Material type – the best choice is pure iron steel. Hardened steels may attract less.
Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Warning for allergy sufferers

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.

Do not drill into magnets

Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Crushing risk

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.

Product not for children

These products are not suitable for play. Swallowing several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.

Shattering risk

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Life threat

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Operating temperature

Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Data carriers

Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).

Safe operation

Be careful. Rare earth magnets attract from a distance and snap with massive power, often faster than you can react.

GPS Danger

A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
