Custom Magnetic Assemblies
Reliable Magnet Assembly Supplier for Motors & Automation
What Is a Magnetic Assembly?
A magnetic assembly is a functional combination of permanent magnets and other metallic or non-magnetic components (such as steel shells, threaded rods, or bonding housings) designed to generate, control, and apply magnetic force efficiently. Compared with standalone magnets, assemblies provide stronger holding power, better protection, and easier mounting in industrial systems.
Mag Spring® offers a wide range of standard and custom magnetic assemblies that integrate advanced materials like NdFeB (neodymium magnets), SmCo, or ferrite, combined with precision-machined housings and protective coatings. Our assemblies are widely used in motors, sensors, automation lines, robotics systems, lifting equipment, and test instruments.
Standard Magnetic Assembly Types
Steel-Shell Magnetic Assemblies
Our steel-covered magnetic assemblies feature high mechanical strength and concentrated magnetic flux. The steel shell protects the magnet from corrosion and mechanical impact while intensifying the magnetic field toward the working surface.
- Available in round, pot, and cup shapes
- Materials: NdFeB or ferrite core with steel housing
- Surface finish: Zinc, Nickel, or Epoxy coating
- Operating temperature up to 200 °C
Threaded Magnetic Assemblies
Designed for convenient mechanical mounting, threaded magnet assemblies come with external or internal threads, allowing easy integration into motors, conveyors, or robotic tools. Widely used in sensor fixtures and automation jigs.
- Standard metric and inch thread sizes
- Strong holding force in compact dimensions
- Custom thread design and depth available
- Optional stainless-steel housing for corrosion resistance

FAQ – Magnetic Assemblies
What’s the difference between a magnet and a magnetic assembly?
A single magnet is a raw material; a magnetic assembly combines magnets and structural components to deliver practical magnetic force and mounting convenience.
Can I request a custom shape or magnetic direction?
Yes, we can manufacture round, rectangular, ring, or irregular shapes with axial, radial, or multi-pole magnetization.
What materials are used for housings?
Common housings include steel, stainless steel, aluminum, or engineering plastics depending on mechanical and corrosion requirements.
How is magnetic strength tested?
We use flux-meters, gauss-meters, and magnetic mapping systems to verify surface flux and magnetization uniformity.
Do you support small batch or prototype orders?
Yes. We offer sampling and low-volume manufacturing for design verification before large-scale production.
