Ceramic tube magnets are a highly economical magnetic separation solution. Available in a standard 1” diameter with length options ranging from 4” to 24”, tube magnets give you many different installation options. Ceramic magnets use a powerful magnetic field to attract and hold various types of ferrous metal debris, including larger ferrous pieces such as large screws, metal chips, washers, nuts, and metal scrap. They are designed to resist wipe-off, meaning that metal contamination will not re-enter material flow once it has been attracted to the surface of the tube magnet. Tube magnets are a great choice for many different industry applications where simple and effective magnetic separation is needed. Bunting Tube Magnets are tapped on both ends with a 1/4″-20UNC thread.
