Segment Rare Earth Magnet for AC Dry Hydraulic Motor Parameter Part No. NSGN45-68 Dimensions Customized sizes Material Sintered Neodymium-Iron-Boron (NdFeB) Shape Arc / Segment Plating Zinc (Zn) Magnetization Direction Diameter Grade N45 Maximum Temperature: 80 Degree Coating: Nickel (Ni) Magnetization: Inside Curve to Outside Curve Dimensional Tolerance +/-0.005″ Neodymium magnets are the most powerful of all permanent magnets. They are often known as “Super Magnets”.
They are used in applications where the strongest magnetic force is required from the smallest possible volume of magnet material. Neodymium magnets are relatively new, they were developed in the mid 1980s and can now be found extensively in countless modern applications from fridge magnets to wind turbines! Threads cannot be manufactured directly into neodymium magnets because they are too hard and brittle, but when integrated into pot magnet assemblies, rear threaded fixings are available in the steel pot magnet shell. Since the introduction of neodymium magnets, the manufacturing cost of neodymium magnets has fallen in line with a massive increase in production capability and now small neodymium magnets are cheap enough to be used in low cost promotional giveaway items.
Neodymium magnets (NdFeB), commonly known as ‘rare earth’ magnets are high-performance permanent magnets constructed from an alloy of neodymium, iron and boron. They are true permanent magnets and will not lose their magnetism unless they are heated to a temperature which exceeds the maximum operating temperature rating or their protective plating is damaged and water ingress causes rusting, which over time will magnetically and mechanically damage the magnets.
