Neodymium Ring Magnet – OD19mm × H4mm × ID8mm | N38
This Neodymium Ring Magnet (OD19mm × ID8mm × 4mm thick) is a compact yet powerful rare earth magnet designed for applications requiring a central hole for shafts, bolts, or alignment fixtures. Manufactured from high-performance N38 grade neodymium, it delivers strong magnetic force in a slim, space-efficient ring profile.
The 8mm inner diameter makes this magnet ideal for mechanical assemblies, sensor mounts, motors, jigs, fixtures, and precision engineering projects where accurate positioning and consistent holding power are critical. Finished with a smooth nickel (NiCuNi) coating, it offers excellent corrosion resistance and a clean, professional appearance.
Key Features
Outer Diameter: 19 mm
Inner Diameter: 8 mm
Height (Thickness): 4 mm
Material: Neodymium (Rare Earth)
Grade: N38
Coating: Nickel (NiCuNi)
Magnetisation Direction: Axially magnetised (through height)
Typical Applications
Mechanical and engineering assemblies.
Electric motors and rotors.
Sensors and encoders.
Jigs, fixtures, and tooling.
Robotics and automation projects.
DIY, prototyping, and hobby applications.
Despite its compact size, this N38 neodymium ring magnet provides excellent holding strength compared to ferrite alternatives, making it a popular choice where performance and reliability matter.
⚠️ Handling Note: Neodymium magnets are brittle and very strong. Handle with care to avoid chipping, pinching, or damage to surrounding items.
