8339 – Ferrite Ceramic Ring Magnet 1.75 OD x 0.85 ID x 5/16 in

SKU 8339 is a Ceramic VIII ferrite ring magnet measuring 1.75 in OD × 0.85 in ID × 5/16 in thick. Ferrite ring magnets are widely used where a central bore, corrosion resistance and economical permanent-magnet material are useful in rotating, holding, speaker and industrial assemblies.

Ferrite Ring Design Notes

The listed pull-force value is a comparison/test value, not a universal safe working load. Real application force depends on the target material, contact area, air gap, surface condition, alignment and load direction.

Ferrite rings are especially attractive for cost-sensitive OEM programs because the ceramic material has excellent natural corrosion resistance and generally does not require protective metallic plating.

Bulk & OEM Ferrite Ring Magnets

For recurring production, custom OD/ID dimensions, alternate ferrite ring geometries or annual-volume pricing, use the Magnet RFQ Builder. Browse all Ceramic / Ferrite Magnets for additional ring, block and disk options.

Use the magnet pull force calculator for preliminary screening and the temperature derating calculator when reviewing thermal exposure. Confirm the final magnetic circuit and assembly conditions.
