Strong Rare-Earth Neodymium Ring Magnets

Neodymium (also known as "Neo," "NdFeb," or "NIB") ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center. Neodymium ring magnets are the most powerful magnets commercially available today, with magnetic properties that far exceed those of other permanent magnet materials. Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials for design optimization, while achieving the same result.

* $15.00 total minimum order (excluding shipping & tax if applicable) - Items can be combined to reach the minimum amount.

*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in the correct context. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Features & Technical Information for Rare-Earth Neo Ring Magnets

Like all rare earth neodymium magnets, neo ring magnets feature exceptional pull strength. They also resist demagnetization, providing a reliable, long-term magnet solution for industrial and commercial applications. We are an industry leading supplier of high-quality neodymium ring magnets, and a trusted source to customers worldwide for licensed permanent magnets of all types.

Manufacturing Methods for Neo Ring Magnets

Our neodymium ring magnets are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include a triple layer nickel (Ni-Cu-Ni) plating, or aluminum IVD coating.

Standard Measurement Tolerances for NdFeB Ring Magnets

Here are the standard tolerances for Rare Earth Magnets (SmCo & NdFeB) based on the following dimensions:

  • +/- 0.004” on OD & ID dimensions ranging from 0.040” to 1.000”.
  • +/- 0.008” on OD & ID dimensions ranging from 1.001” to 2.000”.
  • +/- 0.012” on OD & ID dimensions ranging from 2.001” to 3.000”.

*Tolerance on thickness +/-0.004” regardless of size.
