The steel cup acts as an armature, concentrating the magnetic flux and increasing capacity even several times. Moreover, the metal housing protects the brittle neodymium magnet from cracking upon impact. The bushing with internal thread allows easy screwing of any element (bolt, hook, handle).

Care must be taken not to screw the bolt too deep into the magnet bushing. We recommend checking thread depth before assembly and shortening the screw if necessary. You can use a spacer washer or lock nut to limit screwing depth.

These holders are commonly used in industry, advertising, and construction for quick mounting. They serve as a base for hooks, cable holders, organizers, and lighting systems. Ideal for fixing lighting on machine tools and welding tables.

This value applies to perfect adherence with the entire magnet surface. On a thin surface or painted cabinet, the magnet will hold much weaker (even by 50-70%). For side detachment (sliding), the force is only approx. 1/3 of nominal capacity.

Steel cups are usually coated with a layer of nickel (shiny) or zinc (matte/bright), providing basic protection. For outdoor applications, we recommend additional protection with varnish or choosing a rubberized (hermetic) version. The whole is well protected for standard workshop and industrial applications.

Maximum lifting capacity of the magnet – what it depends on?

The lifting capacity listed is a theoretical maximum value executed under specific, ideal conditions:

with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
with a cross-section of at least 10 mm
with an ideally smooth contact surface
with zero gap (no coatings)
during pulling in a direction vertical to the mounting surface
at room temperature

Magnet lifting force in use – key factors

Real force is affected by working environment parameters, mainly (from most important):

Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

* Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap {between} the magnet and the plate decreases the load capacity.

Pros as well as cons of NdFeB magnets.

Strengths

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

They do not lose strength, even after approximately ten years – the reduction in lifting capacity is only ~1% (based on measurements),
Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by external interference,
By applying a decorative layer of gold, the element presents an elegant look,
Magnets possess impressive magnetic induction on the active area,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Due to the potential of accurate molding and customization to specialized requirements, neodymium magnets can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
Wide application in high-tech industry – they find application in HDD drives, electric drive systems, medical equipment, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices

Limitations

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce 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 during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Safe handling of neodymium magnets

Eye protection

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Avoid contact if allergic

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.

Impact on smartphones

An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.

Heat warning

Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and strength.

Choking Hazard

Neodymium magnets are not suitable for play. Eating several magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Fire risk

Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Life threat

Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.

Powerful field

Be careful. Rare earth magnets act from a distance and connect with massive power, often quicker than you can react.

Bodily injuries

Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Cards and drives

Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Important!
