Product Overview

These 5/8" x 5/8" N45 Neodymium Cylinder Magnets are engineered for applications that demand exceptional magnetic strength and precise positioning. With equal diameter and height, they provide a true cylindrical profile that fits neatly into drilled holes and machined components while delivering a deep, concentrated magnetic field for secure holding power.

Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these magnets offer stronger magnetic performance than N42, N40, N38, and N35 grades. Their impressive 42-pound pull force makes them ideal for industrial equipment, engineering projects, woodworking, robotics, magnetic fixtures, and custom fabrication where dependable performance is critical.

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 embedded mounting, alignment, positioning, magnetic fixtures, and heavy-duty holding applications.

These magnets are magnetized through their thickness (height), placing the north and south poles on the two flat circular ends for maximum magnetic efficiency.

Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.

How Strong Is This Magnet?

This 5/8" x 5/8" N45 cylinder magnet delivers over 42 pounds of pull force under ideal testing conditions using a thick, clean steel surface.

Actual pull force can vary depending on:

  • Surface material
  • Steel thickness
  • Contact area
  • Air gap
  • Mounting method
  • Environmental conditions

For maximum holding performance, use this magnet against a clean, flat, thick steel surface.

Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.

Common Questions About This Magnet

What is the pull force?

This magnet provides over 42 pounds of pull force under ideal testing conditions. Actual pull force depends on the application and contact surface.

Is N45 stronger than N42 magnets?

Yes. N45 delivers greater magnetic strength and energy than N42 magnets of the same dimensions.

Can this magnet rust?

Like all neodymium magnets, it contains iron and may corrode if the protective coating becomes damaged or exposed to moisture for extended periods.

Can it be used outdoors?

Yes. However, additional sealing is recommended for long-term outdoor or marine environments.

What direction is it magnetized?

This magnet is magnetized through its thickness, with the north and south poles located on the two flat circular ends.
