Neodymium ring and tube magnets feature a central bore that makes them ideal for sensor triggers, through-bolt mounting, speaker assemblies, and axial alignment applications. The hollow centre allows wiring, shafts, or fasteners to pass through, giving engineers and designers maximum flexibility. Available in a broad range of outer diameters, inner diameters, and heights, these rare earth rings are precision-ground and nickel-plated for long-term durability. Suitable for robotics, scientific research, instrumentation, and industrial automation applications worldwide.
