We can also polish the ceramic eyelet according to the users requirement, such as a surface finish with semi-polished (Ra 0.8) and fine polished (Ra 0.1).
The table below shows the commonly used specifications of ceramic eyelets.
 
Technical Specifications:

we also offer a hub grooving service for snap ring fitting onto the eyelet that you select. The minimum wall thickness of no thinner then 1.0 mm holds. Three groove widths are available, 1.1, 1.3 and 1.6 mm.

The other ceramic eyelets products:

ceramic rollers, ceramic rolls, ceramic pulleys	ceramic eyelets, ceramic rings, ceramic loops, threaded ceramic eyelets	ceramic eyelet with flange, flanged eyelet, guide eyelet, flange bushing, flanged bush	pigtails, dogtails, hook guides, hooks with metal holder, with metal holder

Notes of the ceramic eyelets usages:
ceramic eyelets for textile , wire and other ceramic sleeve tube hooks is best for textile wire equipments which have a high perfoamance like wear resistance , soomth, high temperature resistance etc features than metal materails parts.

The technical advantages of oxide ceramic thread guide components on the basis of Al2O3, TiO2 and ZrO2can be summarized as follows:

• High wear resistance in high-speed processes
• Accuracy of contours
• Optimally adjustable topography of the thread contact area depending on the application
• Low frictional losses
• Hardly any thread breakage
• No contact reactions with the thread
• Low thread abrasion
• With the use of TiO2 ceramic, no electrostatic charging.
• Reliability and long lifetime over years in the operating conditions

Excellent wear resistance, can improve the service life of textile equipment, ceramic material has a good surface smoothness, which can protect the textile wire line from damage。
