N52 neodymium ring magnet measuring 1″ OD x 3/16″ ID x 1/8″ thick. Axially magnetized with Ni-Cu-Ni coating, 14,500 gauss typical Br, and 12.57 lb listed pull force.
SKU 9734 is an N52 neodymium ring magnet measuring 1 in OD × 3/16 in ID × 1/8 in thick. Axially magnetized and nickel plated, this high-energy ring gives engineers, OEMs, and procurement teams a compact annular magnet for sensing, alignment, shaft clearance, fixtures, prototypes, and production assemblies where higher magnetic output is needed from a small package.

N52 provides higher magnetic energy than lower neodymium grades, but this part also has a lower listed maximum operating temperature. The 3/16 in center opening can provide clearance for a shaft, fastener, pin, or assembly feature while maintaining a broad annular pole face.
The listed pull force is a reference value under defined contact conditions. Air gap, target-steel thickness, contact area, surface finish, temperature, and load direction all affect actual performance. Use the Magnet Pull Force Calculator for preliminary screening and review What Is a True Radial Magnet? when comparing axial and radial ring designs.
