Zirconia Ceramic Small Roller Product Introduction
The precision zirconia ceramic small roller is a high-precision industrial component manufactured from zirconia (ZrO₂) ceramic material, possessing the following significant characteristics:
1. Superior Mechanical Properties: Mohs hardness up to 9 (second only to diamond), wear resistance is 3-5 times that of metal guide rollers, and fatigue life exceeds 250 million cycles.
2. Precision Machining Capability: Surface roughness ≤0.02μm (equivalent to 1/5000 of the diameter of a human hair), enabling nanometer-level guiding accuracy.
3. Adaptability to Special Environments: Operating temperature range from -50℃ to 1200℃, with excellent corrosion resistance and anti-static properties.
4. Chemical Stability: Maintains stable performance in acidic and alkaline chemical media, and its performance is not affected by chemical corrosion.
