Product Description
 | Alumina ceramic :
Alumina Ceramic bushing is produced from 99% alumina raw material. It is shaped by isostatic pressing, high temperature sintering, then inner and outer diameter are processed by precision grinding. |
Ceramic bush: Advantages Good electrical insulation performance, works stably under high temperature environments. High mechanical hardness and wear resistant property for continuous friction working condition. |  |
 | Ceramic parts: Compact ceramic body with low water absorption. Customizable inner diameter, outer diameter, height and dimensional tolerance; secondary operations such as chamfering are supported. Samples and small lot orders are acceptable. |
Ceramcic sleeve: Applications Applied as wear resistant bushing, insulating sleeve, positioning liner for pump assemblies, mechanical equipment, sensor units, high temperature fixtures and electronic devices. |  |
