With overall dimensions of 1268mm × 1268mm × 140mm and tooth surface hardness reaching HRC 58-62, this gear ensures low-noise operation and eliminates image artifacts caused by mechanical vibration. Backed by over 20 years of manufacturing expertise and ISO 9001 certification, we customize ring gears from 50mm to 10,000mm in diameter, complying with AGMA 12-15 and DIN 3-5 standards for demanding medical imaging applications worldwide.
CT Scanner Gear Details
A CT scanner gantry requires exceptional rotational precision to deliver diagnostic-quality images. Our CT Scanner Gear meets this challenge through precision manufacturing processes. Each gear undergoes vacuum carburizing heat treatment, followed by precision grinding to achieve minimal transmission error.
The gear structure incorporates optimized tooth micro-geometry with tip and root relief. This design compensates for elastic deformation under centrifugal loads during high-speed rotation. You benefit from improved dimensional stability over extended scanning sessions, maintaining clearances even as operating temperatures fluctuate.
We produce these gears using high-alloy steels such as 18CrNiMo7-6, selected for low thermal expansion coefficients. This material selection ensures consistent performance in both fixed hospital installations and mobile imaging units.

Features and Benefits
Ultra-High Precision Grinding
Gears are machined to IT6 precision levels. This high accuracy effectively eliminates rotational vibration that causes CT image artifacts, improving diagnostic reliability.
Hardened Tooth Surface
Vacuum carburizing creates a wear-resistant surface layer. The gear delivers extended service life, reducing replacement frequency and total cost of ownership.
Optimized Tooth Geometry
Optimized micro-geometry minimizes backlash and noise. Patients benefit from quieter scanning procedures, while maintaining geometric accuracy in reconstructed 3D images.
Low Thermal Expansion Materials
High-alloy steel construction maintains tight clearances during thermal cycling. This stability ensures consistent performance under varying ambient conditions for mobile CT units.
High Torque Density Design
The gear withstands high centrifugal forces in multi-slice scanner applications. It reliably supports 128-slice or 256-slice systems at maximum rotational speeds.
Applications
High-Speed Multi-Slice CT Systems
Our CT scanner gear supports 128-slice and 256-slice medical scanners. The gear maintains sub-millimeter positional accuracy while withstanding extreme centrifugal loads at high RPM.
Industrial Non-Destructive Testing Equipment
Manufacturing facilities deploy our gears in heavy-duty industrial CT systems. These drive large gantries for scanning aerospace engine components and automotive parts in vibration-prone factory environments.
Mobile Medical Imaging Units
Emergency vehicles and field hospitals demand robust solutions. Our gears withstand external shocks and temperature fluctuations while delivering consistent rotational torque for portable scanners.
Research and Development Facilities
Universities and research centers integrate our precision gears into experimental imaging systems. Custom configurations support prototype development and validation of advanced imaging techniques.
Installation Guide
Pre-Installation Inspection
Verify dimensions against supplied CMM inspection reports. Check mounting surface flatness to ensure compliance with specified tolerances.
Mounting Procedure
