Rare earth rod magnets are extremely efficient at removing fine iron contamination from free-flowing products such as sugar, grain, tea, flour, granulate, and any other types of powder with low moisture content. This item can be supplied with blank, tapped, or studded ends for ease of installation. Rods are 25.4mm (1") in diameter. Magnetic Rods are particularly useful for those engineers who wish to build their own separator units or have severe space restrictions and are not able to accommodate a conventional unit. All product contact parts are manufactured using 316-grade stainless steel. These rod magnets are 0.250 inches (6.4mm) in diameter and 0.750 inches (19.1mm) long. They are magnetized through the length. They are composed of grade 40 neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion-resistant finish. Their individual pull force is approximately 9 lbs. The maximum working temperature is 176 F (80 C).
