Rubber Coated Disc Magnets, Round Rubber Coated Magnet, neodymium disc magnet, the multiple pole design of these rubber coated Neodymium (NdFeB) pot magnets ensures a dense shallow magnetic field on the holding surface. This allows for excellent holding onto thin, lacquered car body metal. The sideways displacement (sheer forces) are extremely good due to the suction effect of the rubber surface. Maximum recommended operating temperature is 60 degrees Celsius.
These rubber coated Neodymium (NdFeB) pot magnets are especially suitable for magnetically fixing objects such as advertising displays or safety blinkers onto car roofs (the metal work must have a mild steel content - aluminium or carbon fibre surfaces will not work). The rubber coated Neodymium (NdFeB) pot magnets are also suitable for fixing signs, plates, temporary lightings and sample parts scratch-free onto highly polished chrome-plated or painted mild steel (ferrous) surfaces.
The rubber coating also provide a good level of corrosion protection in humid conditions. Because of their high performance, slide resisting properties and paint work protection ability, these rubber coated Neodymium (NdFeB) pot magnets are sometimes also known as Boutique Magnets.
Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw. Because these magnets have a rubber-coating they are ideal for using to attract fragile or easily marked surfaces, the rubber coating increases friction, softens impacts and prevents marking. Countersunk magnets with opposite poles on the countersunk face can be used to attract two surfaces or two opposing countersunk magnets with the same pole on the countersunk face can be used to create a damping, shock absorbing or repelling effect. Also available with the north pole on the countersunk face.

Note on adhesive force
The adhesive forces determined by us were determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm with the magnet pulled off vertically (1kg~10N). A deviation of up to -10% compared to the specified value is possible in exceptional cases.
Classy look and high-quality material
Thanks to the elegant look of our Neodymium Magnet System Ø 22 mm - 66 mm black rubber-coated with counterbore hole, they can be placed where they are clearly visible.
