This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. It is commonly used for cleaning flour, sugar, plastic granules, as well as oils and coolants. Thanks to the use of strong neodymium magnets, the rod catches even metallic dust.

The construction relies on a sealed, welded stainless steel housing, polished smooth. The center is filled with NdFeB magnets and pole pieces, arranged to maximize the field on the tube surface. Such construction ensures full resistance to corrosion, water, oils, and acids.

Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. You can use compressed air or special non-magnetic strippers (rings). In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.

The Gauss value tells us how effectively and deeply the magnet will catch contaminants. For basic machine protection against pieces of iron, standard power is sufficient. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.

We fulfill individual orders for bars perfectly matched to your machine or separator. We offer various tip options: threaded holes (e.g., M8, M10), protruding screws, flat pivots, mills, or handles. Contact us for a quote on a non-standard dimension.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their immense field intensity, neodymium magnets offer the following advantages:

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They are extremely resistant to demagnetization induced by external field influence,
A magnet with a metallic nickel surface is more attractive,
They feature high magnetic induction at the operating surface, which improves attraction properties,
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...
Considering the possibility of free forming and customization to specialized projects, NdFeB magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
Universal use in advanced technology sectors – they serve a role in mass storage devices, electric motors, advanced medical instruments, as well as modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Limited ability of producing nuts in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The lifting capacity listed is a result of laboratory testing executed under standard conditions:

using a plate made of high-permeability steel, serving as a circuit closing element
possessing a thickness of at least 10 mm to avoid saturation
characterized by even structure
with total lack of distance (without impurities)
under perpendicular application of breakaway force (90-degree angle)
in temp. approx. 20°C

Magnet lifting force in use – key factors

In real-world applications, the real power is determined by many variables, ranked from the most important:

Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Nickel allergy

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.

Shattering risk

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Mechanical processing

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

GPS and phone interference

Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Finger safety

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Magnetic media

Equipment safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Implant safety

For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.

Adults only

These products are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a severe health hazard and requires immediate surgery.

Thermal limits

Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Respect the power

Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can react.
