Product Description
N42SH Neodymium Arc Magnet – High-Temperature Industrial Motor Grade
Engineered for precision and extreme durability, this N42SH Neodymium Arc Magnet is the industry standard for high-performance motors and generators. The SH Grade designation ensures that this magnet maintains its full magnetic strength at temperatures up to 150°C (302°F), far exceeding standard neodymium grades.
With a 3-inch Outer Diameter (OD) and a precise 90-degree curvature, these arc segments are designed for seamless integration into cylindrical motor housings and magnetic assemblies requiring high torque and thermal stability.

Warranty
This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.Product Videos

Great magnet but does not do well near salt water.
Currently there is no option to purchase this magnet with a protective covering for salt air/water,.
