Strong Rare Earth Neodymium Disc & Cylinder Magnets

Types of disc and cylinder magnets

Disc magnets and cylinder magnets are wide terms and also know as many other names such as round or circular magnets or rod magnets. Our disc and cylinder magnets are mainly divided into these 3 distinct categories.

• Disc Magnets

  

  Disc magnets where thickness is less than diameter

• Cylinder Magnets

  

  Cylinder magnets where thickness is greater than or equal to diameter

• Diametric Disc & Cylinder Magnets

  

  Disc and cylinder magnets with diametric magnetization

Available coatings for disc and cylinder magnets

We provide the below nickel (Ni-Cu-Ni), black nickel (Ni-Cu-Ni-BlackNi), gold (Ni-Cu-Ni + Au), rubber and plastic coatings for our disc and cylinder magnets. Our default coating is a 3-layer nickel-copper-nickel (Ni-Cu-Ni) to protect from moisture and corrosion, enhance durability and to give a nice smooth silver finish. Additional coatings such as epoxy (Ni-Cu-Ni + epoxy) and silver (Ni-Cu-Ni + Ag) available. See custom neodymium disc and cylinder magnets for more details

You can use our magnet finder tool and select metric sizes to find close equivalents to popular metric sizes like 5mm, 10mm, 25mm, 50mm diameters, hole size or thicknesses, etc.
• Tolerances - Dimensional tolerances for all disc and cylinder magnets are 0.004" or 0.1mm.
• Pull force - Testing for all disc and cylinder magnets pull forces was done with precision equipment in real world use situations. You can use our free Magnet Strength Calculator and listed pull force for each product as a reference point, but each use case may present a unique situation and pull force may vary.

Disc and cylinder magnet magnetization directions

We offer disc and cylinder magnets in through thickness and diametric magnetization directions. Most of our disc and cylinder magnets are axially magnetized through their thickness and the rest are diametrically magnetized across the diameter of the magnet. Our disc and cylinder dimensions are listed in order of diameter then thickness. Below are diagrams of two magnetic polarizations we provide.

• Through thickness axial polarization

  

• Through diameter diametric polarization
