Confirm adhesive selection, dimensional stack-up, and the magnetic circuit in the final assembly. Sintered neodymium is hard and brittle; avoid impacts, snap-together collisions, and uneven clamping. The listed pull force is a comparison value, not a guaranteed safe working load. Air gaps, target-steel thickness, surface finish, and shear loading reduce usable holding force.
Use the magnet pull force calculator for preliminary screening and compare materials in the neodymium magnet grade chart. Browse neodymium disk and rod magnets, or submit the magnet RFQ builder for volume pricing or custom requirements.
