Product Overview
These 1" x 1" N48 Neodymium Cylinder Magnets are engineered for applications requiring exceptional holding power and a deep magnetic field in a compact cylindrical design. With equal diameter and height, they provide a perfectly balanced shape that fits neatly into drilled holes, precision assemblies, and heavy-duty magnetic fixtures. Delivering approximately 105 pounds of pull force, they are ideal for demanding industrial and engineering applications.
Manufactured from premium N48 grade NdFeB (Neodymium-Iron-Boron), these magnets offer significantly greater magnetic strength than N45, N42, N40, N38, and N35 grades while providing an excellent balance between performance and value. Whether you're designing machinery, building custom fixtures, creating automation systems, or fabricating industrial equipment, these magnets deliver dependable, long-lasting performance.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished metallic finish.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a permanent magnet manufactured from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Cylinder magnets produce a concentrated, deep magnetic field that makes them ideal for applications requiring maximum holding power in a compact footprint.
This magnet is magnetized through its thickness, placing the north and south poles on the two flat circular ends. Cylinder magnets are widely used in industrial equipment, robotics, automation systems, magnetic fixtures, manufacturing, scientific instruments, and engineering projects.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1" x 1" N48 cylinder magnet delivers approximately 105 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force depends on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
Because cylinder magnets have a relatively small contact area compared to their magnetic strength, actual pull force should always be verified for your specific application.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be tested before use in critical applications.
