Ferrite ring magnet Ø 140 / 65 mm, h. 17 mm, pull force 25 kg

The circular ferrite magnet is one of the largest and strongest magnets in this category. Although it has lower magnetic energy compared to neodymium magnets, it excels in its high resistance to corrosion, moisture and temperatures up to 250 °C. The magnet with an outer diameter of 140 mm, inner diameter of 65 mm and height of 17 mm has a magnetic pull of approximately 25 kg, a weight of 1 kg, and axial magnetisation Y30.

The large outer diameter, robust construction and wide centre hole allow for mounting on larger shafts, hubs or other structural elements. 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.

Both the dimensions and magnetic force make this magnet primarily suitable for industrial use. It finds application in the production of electric motors, generators, magnetic couplings, separation equipment or special machine assemblies where long service life, thermal resistance and reliable operation are essential.

Typical use:

• for electric motors, generators and industrial drives,
• for magnetic couplings and rotary mechanisms,
• for shafts, hubs and axles of machinery,
• for magnetic separators and industrial jigs,
• for the production of technological lines and machine assemblies,
• for demanding electrical engineering applications,
• outdoor use, as they are corrosion-resistant,
• for long-term operation in industrial conditions,
• for applications requiring a large 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.

A magnetic pull of 25 kg, a diameter of 140 mm and robust design place this magnet among the strongest circular ferrite magnets. Use this reliable magnet for demanding industrial applications and long-term operation.
