Retaining magnets GN 57.2 with rubber jacket, in combination with the steel part, form a particularly strong system that shields the magnet, increases the depth of its effect and concentrates the magnetic flux optimally on the rubberized magnetic surfaces. This makes these magnets particularly suitable for use on surfaces that are coated with thick layers of paint or have round or uneven shapes.
The rubber protects sensitive surfaces from being damaged by the magnet and also has a high coefficient of friction, resulting in high lateral displacement forces.
