Other proposals

This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. High magnetic induction on the surface allows catching the finest iron particles.
The rod consists of a cover tube made of high-quality acid-resistant steel (AISI 304 or 316). The core is a precise magnetic system generating high induction (Gauss). Such construction ensures full resistance to corrosion, water, oils, and acids.
Metal contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. You can use compressed air or special non-magnetic strippers (rings). For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
Magnetic induction measured in Gauss (Gs) determines the density of magnetic flux on the rod surface. 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. You can choose a mounting method consistent with your technical design. We ensure fast realization of special orders and technical advice.

Pros as well as cons of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even over nearly ten years – the drop in power is only ~1% (according to tests),
  • They do not lose their magnetic properties even under close interference source,
  • The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
  • Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of custom machining as well as modifying to atypical conditions,
  • Huge importance in advanced technology sectors – they serve a role in HDD drives, drive modules, medical devices, and complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:
  • At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
  • Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these products can be problematic in diagnostics medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum lifting capacity of the magnetwhat contributes to it?

The lifting capacity listed is a measurement result conducted under specific, ideal conditions:
  • on a base made of mild steel, optimally conducting the magnetic flux
  • whose thickness is min. 10 mm
  • with a surface free of scratches
  • with zero gap (no paint)
  • under axial force vector (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in practice – influencing factors

Bear in mind that the magnet holding may be lower influenced by the following factors, starting with the most relevant:
  • Distance (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
  • Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
  • Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
  • Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
  • Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with neodymium magnets
Medical interference

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Compass and GPS

Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Choking Hazard

NdFeB magnets are not toys. Swallowing several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.

Protective goggles

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Fire warning

Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Electronic devices

Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Safe operation

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.

Pinching danger

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!

Permanent damage

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
