Outstanding value for money, these ferrite pot magnets are made of a ferrite magnet sunken in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them a strong hold for their size. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully. This product is often utilised in applications where you require an instant fixing. It can be attached and removed without the need for additional equipment, greatly decreasing downtime and labour. One example where our ferrite pot magnets are handy is in steel containers, where magnets can be used to hold light fixtures, display signage and create storage space. This magnet is versatile and commonly used in conveyor systems, switches, speakers, arts, crafts, science, and DIY. It has a high operating temperature, capable of functioning up to 180 degrees Celsius, and excellent resistance to demagnetisation and corrosion without any extra coating. It can be easily fixed in place with 10mm diameter cap head screws. This strong rare earth magnet offers a 68kg maximum pull from the magnetic surface when in flush contact with a mild steel surface of equal thickness to the magnet. The specifications are: 100mm diameter x 22mm thick with an 11mm diameter plain through hole for a screw or bolt. The steel shell is chrome plated.
