N35 neodymium disk magnet measuring 21.5 × 9.5 mm, axially magnetized and Ni-Cu-Ni plated, with a listed 4,003.04 gauss surface field and 23.83 lb pull force. SKU 8200.
SKU 8200 is an N35 neodymium disk magnet measuring 21.5 × 9.5 mm. It is axially magnetized through the 9.5 mm thickness, with the poles on the circular faces, and finished with Ni-Cu-Ni plating. This solid cylindrical magnet is suited to industrial holding, fixtures, closures, sensors, and production assemblies.

Confirm pole orientation, operating air gap, target-steel thickness, adhesive selection, and dimensional stack-up in the final assembly. The north and south poles are on the two flat circular faces. Its metric geometry suits fixtures, closures, alignment features, prototypes, and production assemblies where this diameter and thickness fit the available space.
The listed 23.83 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. Validate holding performance in the final assembly. Sintered neodymium is hard and brittle; avoid impact, snap-together collisions, uneven clamping, and excessive mechanical stress.
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.
