Set of 2 Magnets. Dimensions in MILLIMETERS of the completed MOTOR ring:: 33.5 mm OD x 27.25 mm ID x x 5 mm thick, 140 degrees arc segments (2 pieces to a set), magnetized inside curve to outside curve. Nickel (Ni) Plated (silver-like shine) Grade N45H. Very, very strong magnetic material. These arc segments are magnetized through their thickness - 1 with the North Pole on the outer diameter and 1 with the South Pole on the outer diameter. Heat rated to 248 degrees F. These magnets will provide MAXIMUM Torque for fast starts and better traction for your RC vehicle. N45 equals very strong magnetic material. The "H" represents a high heat rating. Standard neodymium magnets - those with no extra letter after the number rating - will produce their maximum strength up to 176 degrees F. Beyond 176, standard NdFeB magnets begin to lose strength. These N45H magnets will maintain full strength up to 248 degrees F - perfect for applications which require high heat tolerance - such as some motors.

We are disc NdFeB magnet manufacturer, can supply large disc magnet, our sintered NdFeB magnets are very powerful.
We produce sintered NdFeB magnet in many shapes and sizes, such as disc NdFeB magnet, can also supply large disc magnet with other magnet material including large disc ferrite magnet etc.
