Pin gauges used for precision measurement and positioning require not only dimensional accuracy but also specific material properties. For applications demanding high hardness, wear resistance, and chemical stability, zirconia ceramic pin gauges are an effective choice.

Here, we clearly explain the features of zirconia pin gauges, their differences from cemented carbide gauges, and application examples.

【What is a Pin Gauge?】
A pin gauge is a cylindrical gauge used for measuring dimensions such as hole diameters and groove widths. Typically manufactured through high-precision grinding, they can be finished with dimensional accuracy of ±0.1μm or less.

The most commonly used materials are cemented carbide and zirconia ceramics, each possessing distinct characteristics.

【Features of Zirconia Pin Gauges】
Zirconia ceramics are an advanced ceramic type with the following characteristics:
・High hardness (Vickers hardness ≥1300)
・Excellent wear resistance
・Non-magnetic and electrically insulating
・Superior corrosion and chemical resistance
・High dimensional stability due to thermal expansion coefficient similar to metals

These properties make it effective in the following scenarios:
・Measuring non-magnetic components in contact with metals
・Measurements in corrosive liquid or chemical environments
・Precision measurement applications where even minute displacements matter
・Manufacturing processes requiring clean environments or electrical insulation

【Differences from Cemented Carbide】
Cemented carbide pin gauges are also materials with excellent hardness and wear resistance. However, the following differences exist:

〈Advantages of Zirconia〉
・Non-magnetic and electrically non-conductive
・High chemical resistance and long service life in corrosive environments
・Smooth surface minimizes foreign particle adhesion
・Resistant to minute dimensional changes due to wear

〈Advantages of Cemented Carbide〉
・Slightly superior impact resistance and fracture resistance
・Relatively lower cost
・Extensive machining experience and availability

Selecting the appropriate material based on application and environment enables both precision maintenance and cost-effectiveness.
