GN 51.2 Retaining Magnets Steel, Disk-Shaped, with Tapped Blind Hole, with Rubber Jacket


Product description


GN 51.2 retaining magnets with rubber jacket, in combination with the steel part, form a system that shields and strengthens the magnet and concentrates the magnetic flux optimally on the rubberized magnetic surface.

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.
