Ferrite ring magnet Ø 21 / 13 mm, h. 6 mm, strength 600 g

Ring Ferrite Magnet is among the permanent ceramic magnets. Compared to neodymium magnets, it has a lower magnetic strength, but it is highly resistant to corrosion, moisture and temperatures up to 250 °C. A magnet with an outer diameter of 21 mm, inner diameter of 13 mm and a height of 6 mm has a magnetic pull of approximately 600 g, a weight of 5.8 g and axial magnetisation Y30.

Ferrite magnets are resistant to moisture and common chemical influences. The ceramic material does not corrode, so the magnet can also be used in outdoor environments or in places with higher air humidity. The magnet requires no surface treatment and retains its properties even with long-term use.

The centre hole allows for fitting onto a shaft, tube or guide pin. Ring ferrite magnets therefore serve as components of electric motors, sensors, clutches or other technical equipment where precise centering of the magnet is required.

Possible uses:

• for electric motors, generators and drives,
• for position and speed sensors,
• on shafts, axles and guide pins,
• in technical and electrical equipment,
• for assembly and testing fixtures,
• during repairs and manufacture of machinery,
• outdoor use, as they are corrosion-resistant,
• for long-term technical use,
• for applications using ring permanent magnets.

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 expands the mounting options and the precision of the magnet placement. If you are looking for a durable ring ferrite magnet for technical or electrical use, this size represents a practical and long-term reliable solution.
