Design and application notes

Axial magnetization places the north and south poles on the two flat annular faces. The 6 mm center opening can accommodate a shaft, tube, pin, or fastener while leaving a narrow magnetic ring around the bore.

The listed 5.31 lb pull force is a reference value under specific test conditions, not a universal working-load rating. Air gap, target-steel thickness, contact area, surface finish, temperature, and load direction all influence performance. Use the Magnet Pull Force Calculator for preliminary screening and review What Is a True Radial Magnet? when comparing ring magnetization styles.
