Product Description
High Purity Alumina Ceramic Rings for Textile Applications
Alumina (Al₂O₃) textile ceramic eyelets are precision components designed for coiling machines and spinning/weaving machinery. These ceramic rings serve as essential thread guides that minimize friction and prevent yarn breakage in textile manufacturing processes.
Key Features & Benefits
- High purity 99% Al₂O₃ composition for superior performance
- Exceptional hardness exceeding HRa88 for extended service life
- High density of 3.85 g/cm³ for durability and wear resistance
- Precision surface finishes: standard (Ra0.8), accurate (Ra0.4), and ultra-precise (Ra0.2)
- Available in single-sided and double-sided ultra-precise polishing options
- Reduces thread friction and prevents yarn damage in textile machinery
