Wholesale Neodymium Magnet Tubes

Neodymium magnet tubes are permanent magnets in cylindrical tubes with a central opening. It has a geometric shape with a height (length) more significant than the circumference.

They are widely used as a primary form in various commercial products and industrial equipment. Many of their uses can be found in multiple goods and sectors, including electrical engines, generators, sensors, and magnetic separation devices.

Neodymium magnet tubes are permanent magnets in cylindrical tubes with a central opening. It has a geometric shape with a height (length) more significant than the circumference.

They are widely used as a primary form in various commercial products and industrial equipment. Many of their uses can be found in multiple goods and sectors, including electrical engines, generators, sensors, and magnetic separation devices.

Features

Magnetic discs and neodymium magnet tubes have very similar forms. The main distinctions are that they are relatively longer / taller and have an opening in the middle.

Depending on your uses, you can specify the sizes of the interior openings. A single section of a continuous magnetic tube can provide an even and consistent magnetic field. The total cost may be less than that of a magnetic assemblage of many smaller magnetic pieces.

They are widely used in commercial goods and industrial equipment. The following are some of the most common uses for neodymium magnet tubes.

Small Motors:

Tube-shaped magnets can be used in some popular electric motors to create the magnetic field required for the engine to function.

Sensors:

Magnetic tubes can be used in various sensors, including proximity and location sensors, which sense the existence or orientation of items.

Linear Actuators:

Linear actuators can use neodymium magnet tubes to transform rotational motion into linear motion.

Magnetic neodymium tubes are occasionally used in magnetic bearings, which use magnetic fields to support and propel spinning items.

We provide bespoke neodymium magnets with extensive expertise in producing magnets of different forms. The following are some of the possible issues with this sort of magnet. But don’t worry; we always prioritize quality over cost-effectiveness.

Manufacturing neodymium magnet cylinders presents several hurdles and problems. The most frequent is about exact measurements and limits – for example, the interior or exterior radii must be the correct sizes.

Meanwhile, neodymium magnet tubes can have problems with magnetic homogeneity. The magnetism may not be spread equally along the length of the cylinder, affecting its function.

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

Grades

The strength of a neodymium magnet is determined by the purity of its magnetic field. The grade of a neodymium magnet is represented by a number. A higher figure indicates a stronger magnetic field.

Neodymium magnets come in a variety of grades spanning from N35 to N55, as well as high-temperature categories for specific uses such as H, M, SH, EH, and AH.

You can learn more about neodymium magnet classes by reading our primer. It will assist you in determining which school level is best for you.

Magnetization Directions

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.

Coatings

Neodymium magnets are environmentally delicate. They can deteriorate rapidly due to dampness and other harmful factors.

To increase the longevity of neodymium magnets, we will need to cover their surfaces with a layer or levels of compounds. Meanwhile, the magnets will be more immune to scrapes and other harm due to this.

We can make bespoke neodymium magnets with a variety of finishes. Nickel, copper, urethane, and other materials are among them. Each of them has distinct characteristics and advantages.
