Product Overview
The N48 Neodymium Cylinder Magnet 1/4" x 1/4" delivers enhanced magnetic performance in a perfectly balanced cylindrical design. Measuring 1/4 inch in diameter and 1/4 inch in length, this compact rare earth magnet fits precisely into drilled holes and molded components while providing dependable alignment, secure positioning, and outstanding holding power.
Manufactured from premium N48 grade NdFeB (Neodymium-Iron-Boron), these magnets offer noticeably greater magnetic strength than standard neodymium grades while remaining easy to install and control. They are ideal for woodworking, electronics, engineering, magnetic closures, fixtures, product assemblies, and custom fabrication where increased holding power is required without increasing magnet size.
Each magnet is protected by a durable Nickel-Copper-Nickel triple-layer coating that provides superior resistance to corrosion and everyday wear while maintaining a smooth, polished appearance. Unlike standard epoxy-coated magnets, the triple-layer nickel finish offers significantly greater long-term durability, making these magnets an excellent choice for demanding applications.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Its cylindrical design creates a deeper magnetic field than a similarly sized disc magnet, making it ideal for alignment pins, embedded mounting, magnetic latches, positioning systems, and precision mechanical assemblies.
Because of their balanced dimensions and exceptional magnetic performance, cylinder magnets are widely used in manufacturing, woodworking, robotics, electronics, and countless industrial and DIY applications.
How Strong Is This Magnet?
This N48 cylinder magnet produces approximately 6.3 pounds or more of pull force under ideal conditions against a thick, flat steel surface. Its balanced 1/4-inch diameter and 1/4-inch length provide excellent stability while generating a deeper magnetic field than thinner magnets of similar diameter.
The premium N48 magnetic grade delivers enhanced magnetic performance over N42 and lower-grade magnets, making it an excellent choice for projects requiring compact size and dependable holding power.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, material thickness, surface finish, air gap, and mounting method. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 6.3 pounds or more of pull force under ideal conditions. Actual holding force may vary depending on the application and contact surface.
Is N48 stronger than N35?
Yes. N48 magnets generate substantially greater magnetic strength than N35 magnets while offering an excellent balance of performance and value.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating provides superior resistance to corrosion and is considerably more durable than standard epoxy coatings.
Can it be used outdoors?
Yes. For prolonged outdoor or marine exposure, additional sealing is recommended to maximize service life.
What direction is it magnetized?
This cylinder magnet is axially magnetized through its length, meaning the north and south poles are located on the two circular ends.
Do you offer bulk discounts?
Yes. Super Magnet Store offers competitive wholesale pricing and quantity discounts for manufacturers, distributors, educational institutions, retailers, and OEM customers.
