Cylindrical holders (Type B) distinguish themselves with a large body height, which allows for deep mounting. Used where the magnet must be hidden deep in the material or precisely positioned.
These holders usually have an internal thread (blind or through) on the back wall. It is a precise, durable solution enabling depth adjustment.
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). It is an industrial product, not a precise machine element, although the execution is careful.

Pros as well as cons of neodymium magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
  • They retain their magnetic properties even under strong external field,
  • By covering with a smooth coating of nickel, the element has an nice look,
  • They show high magnetic induction at the operating surface, which increases their power,
  • 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 customize to complex applications,
  • Fundamental importance in modern technologies – they serve a role in mass storage devices, electric drive systems, advanced medical instruments, as well as multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic holder.
  • Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
  • Due to expensive raw materials, their price is higher than average,

Lifting parameters

Highest magnetic holding force – what affects it?

The lifting capacity listed is a theoretical maximum value executed under standard conditions:
  • using a sheet made of low-carbon steel, functioning as a ideal flux conductor
  • with a thickness no less than 10 mm
  • characterized by even structure
  • under conditions of ideal adhesion (metal-to-metal)
  • under axial force direction (90-degree angle)
  • at standard ambient temperature

Lifting capacity in real conditions – factors

Please note that the application force may be lower subject to the following factors, starting with the most relevant:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Warnings
Permanent damage

Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.

Magnet fragility

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

Handling rules

Be careful. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can move away.

Crushing force

Large magnets can break fingers instantly. Never put your hand betwixt two strong magnets.

Adults only

Neodymium magnets are not toys. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.

Precision electronics

A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.

Threat to electronics

Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Fire risk

Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.

Danger to pacemakers

Patients with a heart stimulator should maintain an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
