Direct Drive of Wire Race Bearing in Computer Tomography with SKF

High-end CT scanners demand extreme precision, speed, and reliability to deliver superior image quality while maintaining uptime and cost efficiency. Replacing wear-prone transmission components with a direct-drive wire race bearing assembly can deliver a step-change in performance by improving rotational stability and reducing noise. This provides a strong foundation for embedded sensing, data-driven maintenance, and increased equipment longevity in demanding CT environments.

Our vision is to acquire a solution or jointly develop a compact direct-drive subsystem where torque motors are integrated directly into the bearing assembly. We are targeting larger outer diameters of approximately 300–1800 mm. We expect partners to offer more than conceptual designs: functional prototypes suitable for PoC and early testing are required, followed by a clear roadmap from prototype validation to scalable series production for the selected partner.

We are looking for a direct-drive rotation subsystem for high-end CT gantries that combines torque motors, motor control electronics, and other key components integrated into SKF’s wire race bearing products. The solution should deliver high rotational stability, low noise, and long service life, while enabling embedded sensing capabilities for real-time performance monitoring and predictive maintenance.

SKF is the world’s leading bearing manufacturer, with 17,000 distributors in 130 countries. Collaborating with SKF on providing wireless condition monitoring solutions offers an opportunity to contribute to making industries reduce downtime, improving equipment longevity and making industrial operations more resource efficient. We want to work together and provide you with valuable learnings that enable your company further opportunities within the industry.
