Neodymium ring magnets
Neodymium ring magnets are strong permanent raw magnets produced in extra high quality. Ring magnets have numerous application possiblities within the industrial business area and the magnets are often used in machinery, production facilities, motors, sensors, display systems, etc.
- Larko’s Neodymium ring magnets are magnitized axially
- Ring magnets can be achieved with/without countersunk holes
- Quality grade N35 is used for the neodymium ring magnets. Please contact us if other quality is needed.
- Max temperature: 80 °C
- Tolerance D: +/- 0.2 mm
- Tolerance H: +/- 0.1 mm
- Tolerance d: +/- 0.15 mm

Neodymium ring magnets from Larko Magnet are produced as round disc magnets with hole. The possibility of countersunk holes depends on the dimension in question. Please see further information under Sizes and Variants.
Thanks to the rare earth neodymium material the ring magnets are some of the strongest permanent magnets in the world. Consequently, they provide companies with multiple application possibilities. Larko’s neodymium ring magnets have undergone a special Ni-Cu-Ni treatment which protects the ring magnet and ensures long durability.
Neodymium magnets can corrode in moist environments. The holding forces have been determined at room temperature on a polished plate made of steel ( S235JR according to DIN 10 025) with a thickness of 10 mm by pulling the magnet vertically from the surface (1kg~10N). A deviation of -10 % (max.) in the stated values is possible in exceptional cases. In general, the value will be exceeded.
