Product Description

Product Description

Zirconia Ceramic Plain Ring Gauge

Innovacera developed a series of ceramic accessories for Inside Micrometers, Holtest and Dial Bore Gauges. The ceramic material used mostly is zirconia.

 

The zirconia ceramic setting ring advantages: > High wear resistance and long service life > The coefficient of thermal expansion is very small, the effect of temperature is very small > The hardness is very high, there is no need to worry about surface scars > Ring gauge management is simple (regular inspection interval is long, saving cost)

The Zirconia Ceramic Ring Gauges Technology: * Surface Roughness: Not more than Ra0.1um * Straight Angle: 0.05/φ100 * Parallelism: Not more than0.015mm * Each 0.5mm as one size, from 1mm to 50mm.
