Custom Neodymium Magnet Tubes Manufacturer
Neodymium Magnet Tubes are high-performance cylindrical magnets with a hollow center, combining strong magnetic force with lightweight structural design. Manufactured from premium NdFeB material, these tube-shaped magnets are widely used in sensors, motors, medical devices, filtration systems, holding assemblies, and custom engineering projects.
As a professional neodymium magnet manufacturer, we provide custom Neodymium Magnet Tubes in various sizes, grades, coatings, and magnetization directions to meet your exact project requirements.
What Is a Neodymium Magnet Tube?
A Neodymium Magnet Tube is essentially a ring-shaped magnet with an extended length, creating a tubular form. Compared with standard ring magnets, tube magnets offer:
- Larger contact area
- Higher magnetic stability
- Better alignment in shaft systems
- Lightweight center-hole structure
- Ideal for sliding, guiding, and assembly applications
They are commonly magnetized axially or radially depending on end use.

Key Features of Neodymium Magnet Tubes
Strong Magnetic Power
Made from rare earth NdFeB material, providing extremely high pull force relative to size.
Hollow Center Design
Allows mounting onto rods, shafts, bolts, pipes, or cable systems.
Multiple Magnetization Options
Available in:
- Axial magnetization
- Radial magnetization
- Multi-pole magnetization
Precision Machining
Tight tolerances available for high-end industrial applications.
Corrosion Protection
Coating options include:
- Nickel (Ni-Cu-Ni)
- Zinc (Zn)
- Epossidico
- Oro
- PTFE
- Custom coatings

Dimensional Identification
D for the outer diameter , d for the inner diameter , H for the thickness (height).
If the dimension of neodymium magnet tube is D10 x d7 x 3 mm:
- Its outer diameter is 10 mm
- The inner diameter is 5 mm
- The thickness is 2 mm
Regular neodymium magnet tubes have 1 type of hole: straight holes. Straight holes are drilled vertically into the magnets. It differs from the neodymium ring magnets, that has 2 types: consecutive holes and countersunk holes.
If a magnet tube has a dimension of D10 x M7 x 2 mm:
- Its outer diameter is 10 mm
- The central hole diameter is 5 mm
- And the thickness is 2 mm
Available Dimensions

| Tolleranza | ±0.05mm / Custom |
* Custom sizes welcome.
Direzioni di magnetizzazione
- The magnetization orientation of neodymium magnet tubes is typically tangential magnetization.
- Their uses are pretty comparable. You’ll need their big circular sides to draw metals rather than the two tiny areas on both extremities.
