Ferrite ring magnet Ø 40 / 22 mm, h. 10 mm, strength 2.5 kg

Ferrite ring magnets are a type of permanent ceramic magnet. Compared to neodymium magnets, they have a lower magnetic force, but excel in their resistance to corrosion, moisture, and temperatures up to 250 °C. A magnet with an outer diameter of 40 mm, inner diameter of 22 mm, and a height of 10 mm has a magnetic force of approximately 2.5 kg, a weight of 42 g, and axial magnetisation Y30.

The larger diameter, 10 mm height, and centre hole expand the possibilities for installation and use in technical equipment. The ceramic material does not corrode, making the magnet suitable for outdoor environments or operations with high humidity. The magnet requires no surface treatment and retains its properties even with long-term use.

Thanks to its larger dimensions and higher magnetic force, this ring magnet is suitable for more demanding applications. It is frequently used as a component in electric motors, generators, magnetic couplings, industrial fixtures, or various devices where the centre hole allows for precise seating on a shaft or axis.

Typical use:

• in electric motors, generators, and drive units,
• for shafts, axes, and rotating mechanisms,
• for magnetic couplings and technical assemblies,
• for production, assembly, and inspection fixtures,
• for mechanical engineering and electrical applications,
• during the repair and manufacture of technical equipment,
• outdoor use, as they are corrosion-resistant,
• for long-term industrial use,
• for applications requiring a ring magnet with a centre hole.

You can glue the magnet using magnet glue.

Warning: Do not bring weaker ferrite magnets close to strong neodymium magnets, as this may lead to the demagnetisation of the ferrite magnet.

The ferrite magnet has axial magnetisation Y30 with poles on both circular faces.

The centre hole allows for precise seating on a shaft or axis, and the magnetic force of 2.5 kg expands the possibilities for use in more demanding technical applications. If you are looking for a durable ring magnet for long-term operation, this will be a good choice.
