Classification of Rubber-Coated Pot Magnets

Inner thread rubber-coated pot magnet


On top of the rubber magnetic system, there are flat inner thread rubber-coated pot magnets that are strong enough due to neodymium-nickel. Black is the standard color for inner thread rubber-coated pot magnets. The rubber-coated inner thread pot magnets have the advantages of scratch resistance and child protection.


Standard sizes for flat inner thread rubber-coated neodymium pot magnets are 22mm, 31mm, 43mm, 66mm, and 88mm in diameter. The pulling force of the standard size inner thread rubber coated pot magnet ranges from 3.5kg to 42kg.


Characteristics of inner thread rubber-coated pot magnets


  • Material: neodymium magnet + A3 steel + TPE rubber.

  • Size: 22x6mm, 31x6mm, 43x6mm, 66x8.5mm, and 88x8.5mm.

  • Thread hole: 22:M3-M6; 31:M3-M6; 43:M3-M6; 66:M4-M10; 88:M5-M12.

  • Magnetic force: 3.5 - 42 kg varies with diameter.

  • Color: black, other colors can be customized.


Outer thread rubber-coated pot magnet


On top of the rubber neodymium magnet assembly, there are thread pins of different sizes that are classified as outer thread rubber-coated neodymium pot magnets. The rubber layer increases friction and protects the contact surface. Thread pins make the magnet easy to fix with nuts. Standard sizes for rubber-coated pot magnets with outer thread are 88mm, 66mm, 43mm, 31mm, and 22mm in diameter. The size of the thread pins varies with magnetic force and diameter. Customized packaging and low prices are available for all outer thread rubber-coated neodymium pot magnets.


Characteristics of outer thread rubber-coated pot magnets


  • Material: neodymium magnet + A3 steel + TPE rubber.

  • Size: 22x6mm, 31x6mm, 43x6mm, 66x8.5mm, and 88x8.5mm.

  • Thread hole: 22-m4x 6; 31-m6x 11; 43-m6x 15; 66-m8x 15; 88-M8x15.

  • Magnetic force: 5 - 42 kg varies with size.

  • Color: black, other colors can be customized.


Rubber-coated pot magnet with threaded liner


In this category, all rubber-coated neodymium pot magnets have a threaded liner on top, which makes them popular in magnetic retention applications. Threaded holes and hooks are the most common accessories for rubber-coated neodymium pot magnets with threaded liners.


The standard diameter for inner thread rubber-coated neodymium pot magnets with a threaded liner is 22mm, 31mm, 43mm, 66mm, and 88mm. The threaded liner is usually galvanized. If there is no color requirement, the rubber coating is black.

  • Material: neodymium magnet + A3 steel + TPE rubber.

  • Size: 22x6mm, 31x6mm, 43x6mm, 66x8.5mm, and 88x8.5mm.

  • Thread: 22:M4/M6; 31:M4/M6; 43:M4/M6; 66:M5/M6/M8; 88:M6/M8/10.

  • Magnetic force: 5 - 42 kg varies with diameter.

  • Color: black, other colors can be customized.
