Alumina Ceramic Guide Bushings: Core Guiding Components For Precision Machinery

Alumina Ceramic Guide Bushings: Core Guiding Components for Precision Machinery

Introduction
Alumina ceramic guide bushings are precision mechanical components made from high-purity alumina (Al₂O₃) material, manufactured through advanced isostatic pressing and high-temperature sintering processes. This product features extremely high hardness, excellent wear resistance, and stable chemical properties, maintaining long-term dimensional stability and guiding accuracy under harsh working conditions, making it an indispensable key guiding component in precision mechanical equipment.

Applications

• CNC Machine Tools: Spindle guide bushings, guideway sliders, feed system positioning bushings

• Automation Equipment: Robot guide bushings, conveyor line positioning bearings, precision transmission mechanisms

• Measuring Instruments: CMM guide bushings, optical instrument positioning bearings, precision testing equipment

• Automotive Manufacturing: Engine assembly guide bushings, transmission positioning bearings, automated production lines

Advantages

1. Super High Hardness: Vickers hardness ≥1700HV, wear resistance is more than 10 times that of bearing steel

2. Extremely Low Friction Coefficient: Friction coefficient only 0.05-0.1, reducing power loss

3. Excellent Dimensional Stability: Thermal expansion coefficient 7.2-8.0×10⁻⁶/℃, ensuring accuracy at high temperatures

4. Corrosion Resistance: Resists various cutting fluids, lubricants, and chemical media

5. Long Service Life: 5-8 times longer service life than metal bushings under same working conditions
