SKU 8981: N48 neodymium disk magnet, 1/4" diameter × 1/16" thick, axially magnetized and Ni-Cu-Ni coated. Listed pull force: 1.11 lb; surface field: 3,309 Gauss.
Its thin, compact geometry suits sensors, fixtures, prototypes and space-constrained production assemblies.
SKU 8981 is an N48 neodymium disk magnet measuring 1/4" diameter × 1/16" thick. It is axially magnetized through the 1/16" thickness, placing the north and south poles on the two flat 1/4" circular faces.

N48 provides higher magnetic energy than standard N35 material in the same geometry. Final assembly performance still depends on the complete magnetic circuit, including air gap, target steel, neighboring materials and operating temperature.
The listed 1.11 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Coating, surface roughness, thin target steel and shear loading can reduce usable force.
Use the Magnet Pull Force Calculator for preliminary magnet-to-steel screening or the Neodymium Magnet Grade Chart when comparing N48 with other neodymium grades.
Browse more neodymium disk and rod magnets or use the magnet RFQ builder for production quantities. Confirm adhesive placement and assembly tolerances, and avoid impacts or snap-together collisions because sintered neodymium is brittle.
