Various popular design of 99% Alumina Ceramic Ceramic Thread Guides with high polishing


Applications and Features:


1. Ceramic eyelet guides (Ceramic ring ) and zirconia ceramic eyelet are applied to the coiling machine and spinning and weaving machinery, it is in common use fault silk another piece.

2. Silk thread slides when the job, in China eye outside, for reducing friction, must raise material hardness, smoothness and form.

3. Our company selects and uses 99%'s Al2O3, hardness greater than HRa88, density 3.85, surpasses essence throwing Ra0.2.

4. The alumia ceramic (Textile ceramic eyelet) Zirconia ceramic eyelet is used to set less (friction is also less) location of pressure right.

5. For cost reduction, according to using a request, smoothness polishing handicraft is allotted being (0.8 throw Ra) roughly, is throw (Ra accurate 0.4), surpasses essence throwing (Ra0.2).


Advantages:

1) Wear resistant


2) Corrosion resistant


3) Heat resistant


4) Stable dimensions


5) Long performance life, low friction


Structures:

1. The inside surface Polish degree: Ra0.2~0.8.


2. The material: 99% AI2O3 with density of 3.85.


3. The hardness: HRa88.
