Product Overview
These 7/8" x 1" N45 Neodymium Cylinder Magnets are designed for applications that require exceptional holding power in a compact cylindrical form. The 7/8-inch diameter provides a generous contact surface, while the 1-inch height produces a deep magnetic field capable of delivering approximately 85 pounds of pull force under ideal conditions.
Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver stronger magnetic performance than N42, N40, N38, and N35 grades. They are ideal for industrial machinery, magnetic fixtures, robotics, engineering prototypes, manufacturing equipment, and heavy-duty magnetic assemblies where dependable performance is essential.
Each magnet features a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating that provides outstanding protection against corrosion, scratches, and chipping while maintaining a smooth, polished 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 generate a deeper magnetic field than thinner disc magnets, making them ideal for applications requiring concentrated magnetic force in a compact profile.
This magnet is magnetized through its thickness (axially magnetized), 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, sensors, product assemblies, and engineering applications.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 7/8" x 1" N45 cylinder magnet delivers approximately 85 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 in your intended application.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be tested for your specific application.
