FerriteFerrite Rings are similar to Discs, but are hollow in the center. Less volume means rings are not as strong as comparable discs, however the hollow center makes them far more versatile - rings easily slide on to tubes or rods.
Our Ferrite Rings are available up to 145mm diameter. Pull strengths are not given for rings since they vary at different points of the ring.
The dimensions for rings are Outer Diameter x Inner Diameter x Thickness (mm).
