Bar magnets of Neodymium-iron-boron (NdFeB)

Bar magnet of NdFeB, brass body, with internal thread and fitting tolerance h6

PRODUCT INFORMATION:
To differentiate the otherwise identical SmCo series the NdFeB bar magnets are coloured blue on the holding surface. Direct mounting of the bar magnet in iron reduced the holding power by up to 15% due to magnetic short circuiting. To avoid this, certain distances need to be maintained between the brass casing of the bar magnet and the iron. The distances are also to be adhered to if the bar magnet was shortened by dimension A. Please refer to the above column for recommended distances (distance mm).

The holding surface is ground and therefore not galvanised.

Alternative to the standard we also offer individual solutions:
» Stainless steel housing
» Housing completely galvanised to better corrosion protection
» Higher holding power
» Higher temperature until 280 °C
» Stainless steel pole shoes

* The forces have been determined at room temperature on a plate in polished steel (S235JR according to DIN 10 025) with a thickness of 10 mm (1kg ~ 10N). A maximum deviation of -10% compared to the specified value is possible in exceptional cases. Value is exceeded in general. Depending on the type of application (installation situation, temperatures, counter anchor etc.) the forces can be influenced enormously. The indicated values are serving as an orientation.
