Product Description

Polished Solid 95% 99% Alumina Ceramic Yarn Roller Guide for Textile machinery


Description of alumina ceramic yarn roller guide

Our ceramic yarn roller guides are as varied as our pulley, both single or multiple grooves are available, also the dimensions can be customized. These ceramic roller guides are made of 96%, 99% or 99.5% aluminum oxide ceramics, call it alumina, with diamond polished running surfaces.

Alumina is a kind of improved technical ceramics, these ceramic yarn rollers promote the winding efficiency a lot in textile machinery because of its low friction, superb wear resistance, anti-static electricity features. 

Specification of alumina ceramic yarn roller guide

1. Raw material: 95% alumina, 99% alumina, zirconium oxide, titania

2. Dimensions: min. diameter can be 10mm, max. diameter can be 50mm

3. Design: single groove, double grooves, or multiple grooves 

4. Tolerance: general tolerance ± 1% of the dimensions, or better via a precision process

5. Surface finish: mirror surface, to be Ra0.3 ~ 0.4 for 95% alumina ceramic eye, to be Ra 0.2 ~0.3 for 99% alumina ceramic eye

Features of alumina ceramic yarn roller guide:  

1. Exceptional hardness, bending strength, toughness

2. Good insulation, anti-magnetic, free static electricity

3. Corrosion resistance in harsh working conditions 

4. Excellent thermal shock resistance and good thermal stability

5. Nox-toxic, healthy material, eco-friendly material

6. Meet with RoHS, REACH regulation completely
