Design Scenario This guide uses an illustrative micro NdFeB ring magnet for a miniature precision assembly to show what a buyer should specify. It does not document a particular customer project or a completed production result. A small ring with a center hole needs a combined review of outer and inner diameter, wall thickness, length, […]
Introduction Countersunk neodymium magnets are widely used when a magnet needs to be mechanically fixed with a screw. They are common in furniture, access panels, display fixtures, enclosures, packaging, tool holders, signage, equipment covers, and custom magnetic assemblies. Compared with plain disc magnets, countersunk magnets are easier to mount securely because the screw head sits […]
Seven checks for SmCo cylinder magnets, from finished dimensions and pole direction to grade review, operating conditions and sample acceptance.
Introduction When engineers design miniature magnetic components, it is common to ask for the strongest possible NdFeB magnet grade. At first glance, the choice may seem simple: if N54 is stronger than N48, then N54 should be better. In real miniature designs, however, the answer is rarely that simple. For very small magnets, the final […]
Introduction NdFeB disc magnets are widely used in sensors, motors, magnetic couplings, positioning devices, encoders, holding systems, and compact mechanical assemblies. Most standard disc magnets are axially magnetized, meaning the north and south poles are located on the two flat faces of the magnet. However, some applications require a different magnetic field direction. In these […]
In the rapidly evolving landscape of modern precision engineering and smart manufacturing, the demand for highly precise, geometrically complex, and mechanically robust magnetic components is at an all-time high. From automotive sensors and advanced robotics to micro-motors in home automation, traditional sintered magnets often face severe limitations due to their inherent brittleness, design constraints, and […]
