No thread rod
A samarium cobalt -magnet in a tall iron housing. This serie has an outer diameter with h6 tolerance according to ISO 286-2.
The A marking on the drawing is the maximum distance the article can be cut or machined without damaging the magnet or function.
The stated 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.
