Description of zirconia ceramic eyelet guide:
Zirconia ceramic eyes are extremely versatile parts in wire, thread, cable, fiber passaging applications because the material is very hard, wear-resistant, and chemical resistant, and the working surface can be polished to a smooth finish. Our facility provides ceramic eyes in a wide range of standard sizes and configurations to meet your needs. We also offer custom ceramic eyelets, ceramic eyes designed and manufactured to match your exact requirements, including different materials, special shapes.
