Ultra High Precision Ceramic Ring Gauges Ceramic Setting Ring

Innovacera developed a series of ceramic accessories for Inside Micrometers, Holtest and Dial Bore Gages. 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.

Size Dimensional interval Roundness Outer diameter tolerance: Inner diameter tolerance Hardness
