8246 – N35 Neodymium Ring Magnet 0.745 OD × 0.336 ID × 0.125 in

SKU 8246 is an N35 neodymium ring magnet measuring 0.745 inch OD × 0.336 inch ID × 0.125 inch thick, with Ni-Cu-Ni plating. Its low-profile ring shape provides a center opening for a shaft or locating feature while maintaining an annular magnetic contact face.

Design notes for SKU 8246

Axial magnetization places the poles on the flat annular faces. Check inside-diameter clearance and the listed tolerance against the mating component. Support the thin ring in its housing and avoid tightening hardware directly against the brittle magnet or forcing it onto a shaft.

Check the complete assembly at the intended air gap and loading direction. Listed pull force is a comparison value, not a safe working load; target steel thickness, contact area and surface condition affect actual holding force. Provide clearance in the housing and protect the brittle magnet from impact during installation.

The listed maximum temperature is 80°C. Evaluate the complete magnetic circuit at the intended operating temperature, including opposing fields and required performance. Check any adhesive or housing material against its own limits. Use controlled handling and keep the plated or coated surface protected during assembly.
