It is a ready-made mounting element that allows quick creation of a magnetic point. 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.
The screw is solidly seated in the cup, however, moderation must be maintained when tightening the nut. Do not use the magnet as a structural bolt transferring huge mechanical loads in shear. The construction is durable and adapted to industrial conditions.
Above this temperature, the magnet may irreversibly lose some of its power. We also offer holders made of ferrite magnets (resistant up to 200°C) or special high-temperature versions. Avoid mounting directly on hot engine or machine components.
We use standardized threads that fit typical nuts available in every store. Stud length varies depending on the model (usually from 8 to 15 mm). It is a solid threaded connection, ready for use.
The magnetic system in a cup is more energy-efficient than the magnet itself of the same dimensions. However, such a system works point-wise and requires direct contact with metal.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
  • Magnets very well resist against demagnetization caused by foreign field sources,
  • By applying a smooth layer of gold, the element has an nice look,
  • Magnetic induction on the working part of the magnet remains impressive,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to versatility in constructing and the capacity to customize to unusual requirements,
  • Universal use in modern technologies – they are used in data components, motor assemblies, medical devices, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Limitations

Disadvantages of neodymium magnets:
  • At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
  • They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing threads in the magnet and complex forms - recommended is cover - magnet mounting.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

Magnet power was defined for the most favorable conditions, including:
  • on a base made of mild steel, effectively closing the magnetic flux
  • with a cross-section minimum 10 mm
  • with a plane cleaned and smooth
  • with zero gap (no coatings)
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

It is worth knowing that the application force may be lower depending on the following factors, starting with the most relevant:
  • Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
  • Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
  • Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets
Mechanical processing

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Crushing force

Pinching hazard: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Do not underestimate power

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Magnets are brittle

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

Electronic hazard

Do not bring magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Skin irritation risks

A percentage of the population experience a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact may cause skin redness. We strongly advise use safety gloves.

Life threat

People with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.

Do not overheat magnets

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.

Keep away from electronics

GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Choking Hazard

Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
