SKU 8314 is an N42 neodymium ring magnet measuring 0.375 inch OD × 3/16 inch ID × 1.5 inches long, with an epoxy coating. Its elongated hollow cylindrical geometry provides a center passage for assembly clearance. Confirm both the bore size and length against the mating components before selecting this part.

Design notes for SKU 8314
The ring is axially magnetized along its 1.5-inch length, with poles on the annular end faces. Support the long body in its housing and avoid bending, impact or an interference fit around the bore. Protect the epoxy finish from scratching and validate the coating against moisture, chemicals and contact materials in the intended environment.
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.
