On a winding or spooling line the guide is the part the wire touches thousands of times per minute. These six-arm alumina star discs separate and guide wire or yarn with a polished, groove-free alumina surface: no scratching, no static build-up, and no metal pickup to contaminate the wire.
Compared with hardened steel or coated guides, alumina runs cooler against moving wire and wears far slower — the guide often outlives several batches of the metal parts it replaced. Arm count, arm profile and bore are machined to your machine's pitch and speed.

Haorui Industrial has machined non-standard advanced ceramics since 2006 (ISO 9001). Send us a 2D drawing (PDF/DWG) or a sample: we quote with tolerance and material recommendation, produce 1–10 piece prototypes in 7–15 days, and keep the process data for repeat batches. Materials available: 95% / 99% / 99.5% Al2O3, ZrO2, Si3N4, SiC, AlN, macor.
No — the guide faces are polished to Ra ≤ 0.4 μm and are harder than the wire, so it is the wire's coating that survives, not the guide.
Yes. Send the drawing or the used part; we reproduce arm count, spacing and bore to fit your machine.
We supply the ceramic part; assembly with metal hubs or bearings can be quoted on request.
Quality you can verify: Haorui Industrial operates an ISO 9001:2015 certified quality management system (scope: precision mechanical ceramics parts), and our alumina and zirconia ceramics are RoHS 2.0 compliant — tested per IEC 62321 by an accredited third-party laboratory. We exhibit every year at CIOE (China International Optoelectronic Exposition) and semiconductor industry expositions in Shenzhen — visit our booth to see the parts in person.
