Description of ceramic eyelet(ceramic ring) :
The ceramic eyelet(ceramic ring) is the most commonly used component for the
wire passing, and it is used in the wire passing position of the coil winding machine
and the textile machinery. Normally it is used for less demanding occasions. The
shape, finish and the hardness of materials must be improved in order to reduce
the friction because of the wire sliding in the surface of the ceramic rings. According
to the requirements, the polish degree of porcelain eye can be regarded as
roughness polishing, precision polishing and ultra-precision polishing.
Features of ceramic eyelet(ceramic ring) :
1.The inside surface polish degree : Ra0.2~0.8.
2.The material : 99% AI2O3 with density of 3.85.
3.The hardness : HRa88.
Materail : alumina ceramic (95 /99 alumina ceramic , steatite ceramics , zirconia ceramics are optional )
Excellent abrasion performance
long working life.
Exact surface finish can reach to 0.2 .
Thread is not damaged easily in the process of sliding .
We are a manufacture , we produce professional textile ceramic .
