GN 57.1 Retaining Magnets Neodymium, Iron, Boron, with Tapped Hole, with Rubber Jacket

Type: A - With 1 tapped hole
Color: SW - Black

Standard Sheet GN 57.1 Print This Page More Information on Retaining Magnets Plastic Characteristics

Product description

Retaining magnets GN 57.1 with rubber jacket, in combination with the steel part, form a system that shields and strengthens the magnet and concentrates the magnetic flux optimally onto 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.
