Technical details
Product Description
Details

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 Variations.

 

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 are also produced as disc magnets, block magnets and sphere magnets.

 

Remarks

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.
