Neodymium Ring Magnets
Neodymium ring magnets are sintered NdFeB permanent magnets with a central hole for mounting around shafts, fasteners or other components. Their compact ring design makes them suitable for sensors, positioning devices and industrial magnetic assemblies.
We manufacture neodymium ring magnets in various sizes and magnetic grades, including the 10mm OD × 6mm ID × 3mm specification. Custom dimensions, coatings and magnetization options are available to meet different application requirements.
Products Description
Our 10mm OD x 6mm ID x 3mm neodymium ring magnets are made from sintered NdFeB with a 10 mm outer diameter, 6 mm inner diameter and 3 mm thickness. The 6 mm center hole leaves a 2 mm radial wall and provides clearance for shafts, fasteners or sensor components.
These magnets feature Ni-Cu-Ni plating and standard axial magnetization, with the magnetic poles on the two flat ring faces. They are suitable for compact assemblies where a central opening is required.

Applications and Magnetization Options
These small neodymium ring magnets are used in shaft-mounted components, sensors, positioning devices and compact magnetic assemblies. The central hole allows the magnet to fit around a shaft or leave space for other components.
Axial magnetization is the standard option for applications requiring magnetic poles on the flat faces. Diametrical or multipole magnetization may be considered for specific sensor and encoder designs, depending on the required field pattern and manufacturing feasibility.
Custom Neodymium Ring Magnets
As a manufacturer with our own production facilities, we can produce neodymium ring magnets with different outer diameters, inner diameters, thicknesses, grades and coatings.
For applications requiring precise alignment, bore concentricity and dimensional tolerances can be specified according to customer drawings.
Please provide the required OD, ID, thickness, magnetic grade, magnetization direction, operating temperature and order quantity.
