Product Specification

Beige Multi-Hole Rectangular Ceramic Bracket (Industrial Grade Precision Support Frame)

Product Introduction

This product is an industrial-grade support bracket manufactured using high-purity alumina ceramic (Al₂O₃ ≥ 99%). It features a beige rectangular block structure with a precision-ground surface achieving an industrial-grade flatness of Ra ≤ 0.8μm. The patented design incorporates four corner circular through-holes combined with distributed mounting screw holes, ensuring main support stability while providing flexibility for multi-angle installation and positioning. The product fully utilizes the material properties of alumina ceramic, including high rigidity, low thermal expansion, and excellent insulation, specifically developed for high-stability support frames and positioning systems in precision equipment.

Core Advantages

• Ultra-high Structural Strength: Flexural strength ≥ 350 MPa, load-bearing capacity up to 120 kg/cm², superior to metal brackets of the same specification.

• Exceptional Corrosion Resistance: Resists corrosion from acid, alkali, solvents, and organic media (except hydrofluoric acid), increasing service life by 5 times.

• Precision Thermal Stability: Thermal expansion coefficient of 7.2 × 10⁻⁶/°C, maintaining dimensional stability in working environments from -50°C to 800°C.

• Excellent Insulation Performance: Volume resistivity > 10¹⁴ Ω·cm, dielectric strength 25 kV/mm.

• Lightweight Design: Density of 3.9 g/cm³, 40% lighter than stainless steel brackets.

Primary Applications

• Precision Measurement Equipment: Support frames for coordinate measuring machines, bases for laser inspection platforms.

• Semiconductor Manufacturing: Positioning platforms for lithography machines, brackets for wafer handling systems.

• Medical Equipment: Support structures for CT scanners, positioning frames for medical robots.

• Automation Systems: Bases for high-precision linear modules, installation platforms for robots.

• Optical Instruments: Support frames for spectrometers, vibration isolation bases for optical platforms.

Usage Instructions

1. Installation Base Requirements: Installation surface flatness should be ≤ 0.1 mm/m; using an epoxy resin leveling layer is recommended.

2. Fastening Specification: Bolt torque should be controlled between 8-12 N·m, using a cross-symmetrical tightening sequence.

3. Thermal Compensation Design: Use spring washers or belleville disc springs when connecting to metal parts to compensate for differential thermal expansion.

4. Anti-Vibration Measures: Adding a silicone damping layer at contact surfaces is recommended to absorb high-frequency vibrations.

5. Regular Maintenance: Inspect screw hole threads every six months; use anhydrous ethanol for cleaning.

After-Sales Service

• 18-month extended warranty period.

• On-site installation guidance service.

• 48-hour emergency failure response mechanism.

• Support for small-batch trial production (minimum order: 5 pieces).

• Establishment of a lifetime product file system.

FAQ

1. Q: What are the unique advantages compared to silicon carbide brackets?
   A: Insulation performance is 3 orders of magnitude higher, cost is 40% lower, making it more suitable for electronic equipment and measuring instruments.
