CT gantry bearing

Precision CT Gantry Bearings: The Heart of Medical Imaging Systems

As a professional ZZ manufacturer specializing in high-precision rotary solutions, we understand that in the medical field, there is no room for error. Our CT Gantry Bearings (also known as CT Scanner Slewing Bearings) are engineered to provide the ultra-high rotational accuracy, rigidity, and quiet operation required by modern Computed Tomography systems.
Designed to support the heavy rotating frame of a CT scanner while maintaining sub-millimeter precision, our bearings ensure clear imaging and patient safety. We replace the "joint" of the machine with a masterpiece of engineering.

🏆 Product Performance & Quality

Our CT gantry bearings are not just standard industrial parts; they are precision medical components. We utilize advanced manufacturing techniques to meet the rigorous demands of medical imaging equipment.
  • High Rotational Accuracy: Engineered to minimize runout, ensuring that the X-ray source and detectors remain perfectly aligned during high-speed rotation.
  • Low Friction & Noise: Optimized raceway geometry and high-quality lubrication ensure silent operation, reducing patient anxiety and mechanical vibration.
  • Rigidity & Load Capacity: Despite their precision, these bearings are designed to handle significant axial, radial, and tilting moment loads caused by the heavy gantry structure.
  • Long Service Life: Manufactured from vacuum-degassed bearing steel with specialized heat treatment, ensuring durability and stability over millions of rotation cycles.

❓ Câu hỏi Thường gặp (FAQ)

Q1: What is the difference between a standard slewing bearing and a CT Gantry Bearing?
A: A CT Gantry Bearing requires much higher precision (P4/P2 level) and lower noise levels compared to standard industrial slewing bearings used in construction machinery. The tolerance for vibration is near zero to prevent image artifacts.
Q2: Can you manufacture a replacement for [Specific CT Model] bearings?
A: Yes, as a professional manufacturer, we can reverse-engineer or manufacture to print for most major CT scanner models. Please provide the part number or dimensions.
Q3: What is the lead time for these bearings?
A: Standard samples usually take 7-15 days. Customized medical batches typically require 30-45 days depending on the quantity and testing requirements.
Q4: Do you provide testing reports?
A: Yes, every batch comes with a Material Certificate and a Dimensional Inspection Report. We can also provide vibration test reports upon request.
