The retaining magnets GN 57.2 with rubber jacket form a system together with the steel part that is especially strong, shielding the magnet, increasing the depth of its effect and optimally concentrating the magnetic flux on the rubberized magnetic surfaces.

This makes these magnets particularly well suited for use on surfaces that may have thick coats of paint or feature rounded or uneven shapes.

The rubber protects sensitive surfaces from being damaged by the magnet and also delivers a high friction coefficient, resulting in high lateral displacement forces.
