The zirconia ceramic measuring wheel is a high-precision motion component that features a zirconia ceramic outer ring combined with a high-precision metal bearing. This wheel is manufactured using an internal and external grinding process, ensuring exceptional precision, smooth rotation, and outstanding wear resistance. It is widely used in semiconductor processing, automated measurement systems, electronics manufacturing, and precision instruments.
✅ Ultra-High Precision – Achieved through internal & external cylindrical grinding, ensuring micron-level accuracy and a smooth surface finish.
✅ Superior Wear Resistance – Zirconia ceramic is significantly harder and more wear-resistant than traditional metals or alumina ceramics, ensuring long service life.
✅ Low Friction & Smooth Rotation – The fine grinding process ensures minimal rolling resistance, improving measurement accuracy.
✅ Excellent Corrosion & Heat Resistance – Resistant to acids, alkalis, and high temperatures, making it ideal for harsh industrial environments.
✅ High Strength & Impact Resistance – Compared to alumina ceramics, zirconia ceramic has higher fracture toughness and greater flexural strength, reducing the risk of breakage under heavy loads.
Zirconia Ceramic Precision Grinding – The wheel undergoes internal and external cylindrical grinding, resulting in an ultra-smooth surface with superior dimensional accuracy.
High-Performance Bearing Integration – The inner metal bearing is finely fitted to ensure smooth motion and long-lasting performance.
Polished Surface Finish – The final precision grinding and polishing significantly reduce surface roughness, ensuring optimal rolling performance.
Outer Layer: Zirconia Ceramic (ZrO₂)
High hardness and wear resistance, providing long-lasting durability.
Smooth, polished surface reduces friction and enhances measurement accuracy.
Inner Layer: High-Precision Metal Bearing
Made of stainless steel or hybrid ceramic bearings for smooth, low-noise operation.
Designed for high-speed rotation and continuous use in automation systems.
Semiconductor Industry – Used in wafer transport, photolithography equipment, and high-precision motion control systems.
Precision Measurement Instruments – Ideal for laser measurement devices, industrial metrology systems, and displacement sensors.
Electronics Manufacturing & Automation – SMT pick-and-place machines, PCB inspection equipment, and high-precision conveyor systems.
Medical Equipment – Applied in biotechnology analysis instruments and automated laboratory devices.
Other Industrial Applications – Suitable for environments requiring high precision, low friction, and extreme durability.
Unlike molded or sintered ceramic wheels, our zirconia measuring wheels undergo internal and external grinding, ensuring a higher level of precision and surface smoothness. This results in:
✔ More accurate measurement with minimal rolling resistance.
✔ Greater durability for long-term, high-load applications.
✔ Consistent performance in high-speed and harsh industrial environments.
