U-magnets
U-magnets are AlNiCo (AN) magnets and are manufactured by casting, with a red lacquer coating, which allows them to be used at temperatures up to 180 °C. To avoid negatively impacting the magnetic properties, the fastening screws should be made of a non-magnetic material such as stainless steel, brass or plastic.
U-shaped magnets: strong magnetic field and precise fixation
U-shaped magnets are one of the most effective solutions when it comes to creating a strong, directional and stable magnetic field. Due to their special “horseshoe” shape, these magnets concentrate magnetic forces between two poles, making the attraction zone extremely precise and powerful. This allows for reliable attraction and fixation of metal parts even in difficult industrial situations.
How do U-shaped magnets create a stronger field?
The shape of the magnet allows the pole areas to be brought closer together, thus creating a concentrated magnetic circuit. Such a design solution reduces magnetic field losses and increases the strength of the attraction. As a result, U-shaped magnets are used where high force and a precisely defined area of action are required, for example, in metalworking equipment, lifting mechanisms or measuring instruments.
Why are they ideal for fixing metal parts?
Thanks to their enhanced pulling force, U-shaped magnets can securely hold even heavier or larger parts. They are particularly useful in assembly lines, temporary fastening processes, magnetic grippers or transport solutions. The U-shaped design allows the part to be inserted between the poles, ensuring a stable hold without the risk of slipping.
How to choose the right U-shaped magnets?
When choosing a magnet, it is important to consider:
– magnet size and material (neodymium, ferrite, alnico),
– tensile strength,
– temperature and environmental resistance,
– installation type.
For heavy loads or precision work, more powerful neodymium U-shaped magnets are recommended, and for standard applications, ferrite magnets.
What are the advantages of U-shaped magnets?
Compared to disc or cylindrical magnets, they provide:
– a more directional magnetic field,
– higher concentration at the fixation point,
– better adhesion to uneven surfaces.
These properties make U-shaped magnets a reliable choice in both industrial and technical applications where strong and precisely controlled magnetic fixation is required.
