Product Overview
These 3/4" x 3/4" N52 Neodymium Cylinder Magnets deliver maximum magnetic strength in a perfectly balanced cylindrical design. With equal 3/4-inch diameter and height, they fit precisely into drilled holes, machined components, and custom assemblies while generating an exceptionally deep magnetic field for demanding applications.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets provide the highest commercially available magnetic strength. Their impressive 60-pound pull force makes them ideal for industrial equipment, robotics, manufacturing fixtures, woodworking, magnetic tooling, product assemblies, and other applications where maximum holding power is required.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing outstanding 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 generate a deeper magnetic field than flat disc magnets, making them ideal for applications requiring concentrated magnetic force in a compact cylindrical shape.
These magnets are magnetized through their thickness (height), placing the north and south poles on the two flat circular ends. Their design makes them ideal for magnetic fixtures, positioning systems, robotics, industrial tooling, sensors, magnetic separators, and embedded mounting applications.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 3/4" x 3/4" N52 cylinder magnet delivers over 60 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force may vary depending on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
Because cylinder magnets have a relatively small contact surface, actual pull force should always be verified in your intended application.
Note: Pull force values are estimates based on ideal laboratory conditions.
