It is the "heart" of every magnetic filter used in industry for cleaning raw materials. Its task is separation (separation) of metal filings from the transported material. High magnetic induction on the surface allows catching the finest iron particles.
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. Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Metal filings stick to the surface very strongly, so cleaning requires strength or cleverness. 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. For the food and precision industry, we recommend the highest induction parameters.
We fulfill individual orders for bars perfectly matched to your machine or separator. The rod end is strictly adapted to the fastening system in your device. We ensure fast realization of special orders and technical advice.

Advantages and disadvantages of neodymium magnets.

Strengths

Apart from their superior power, neodymium magnets have these key benefits:
  • They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
  • Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
  • The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
  • Magnets have very high magnetic induction on the outer layer,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to the possibility of precise molding and customization to unique solutions, magnetic components can be created in a variety of shapes and sizes, which increases their versatility,
  • Huge importance in advanced technology sectors – they are utilized in computer drives, motor assemblies, precision medical tools, and modern systems.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: tips and applications.
  • At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
  • We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
  • Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
  • Due to expensive raw materials, their price is relatively high,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what affects it?

The load parameter shown refers to the maximum value, measured under laboratory conditions, meaning:
  • with the application of a yoke made of special test steel, guaranteeing maximum field concentration
  • possessing a massiveness of at least 10 mm to avoid saturation
  • with an polished contact surface
  • under conditions of no distance (metal-to-metal)
  • during detachment in a direction vertical to the mounting surface
  • at standard ambient temperature

Practical aspects of lifting capacity – factors

Real force impacted by specific conditions, including (from most important):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Plate thickness – too thin steel does not close the flux, causing part of the power to be lost into the air.
  • Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
  • Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safe handling of NdFeB magnets
Adults only

NdFeB magnets are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.

Keep away from electronics

A powerful magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a device to prevent damaging the sensors.

Conscious usage

Handle with care. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.

Implant safety

Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Bone fractures

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Eye protection

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

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.

Operating temperature

Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Safe distance

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Fire warning

Dust created during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
