J.W. Winco: Retaining magnets
J.W. Winco, Inc. offers GN 51.7 Retaining Magnet Assemblies with ball knob or key ring, with rubber jacket, in metric sizes.
These RoHS-compliant magnet assemblies have a zinc-plated steel housing and a magnet of neodymium, iron, and boron (NdFeB). The rubber jacket is made of black Elastomer (TPE). Assemblies are offered with matte black technopolymer plastic (Polyamide PA) ball knob or nickel-plated steel key ring.
These retaining magnet assemblies with rubber jacket are especially suitable for applications where the surface is easily marred. Also, the magnets have an increased coefficient of friction, which creates high lateral retaining force. They are temperature resistant to 175 °F (80°C). Offered diameters are 22, 31, and 43 mm, with nominal pulling forces of 35, 75, and 85 N respectively.
