Design notes for thin N52 disk magnets

Confirm pole orientation, operating air gap, target-steel thickness, adhesive selection, and dimensional stack-up in the final assembly. N52 neodymium provides high magnetic energy, but its 60°C / 140°F maximum operating temperature makes thermal validation important. Sintered neodymium is hard and brittle, so avoid impact, snap-together collisions, uneven clamping, and excessive mechanical stress.

The listed 6.13 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, surface roughness, coating, thin target steel, and shear loading can reduce usable force.

Use the magnet pull force calculator for preliminary magnet-to-steel screening and compare material options in the neodymium magnet grades chart. Browse our magnet catalog or submit the magnet RFQ builder for volume pricing or a custom requirement.
