A Greenwood Rare Earth Magnetic Tube 12000 gauss- mirror finish

Greenwood magnetic tubes (magnetic rods) are a simple low-cost form of magnetic separation. Used in a variety of industries from food or plastics processing to chemical and powder processing, they can be easily installed into machinery or assembled according to the wishes of the customers. Encased in 316 stainless steel tube 25.4mm diameter, they are manufactured with high intensity rare earth magnets (up to 12,000 gauss). We manufacture them specifically to the length requested by the customer. The sealed stainless steel ends can be left blank or drilled and tapped for fixing purposes.
