Ball Bearing Polygon Scanners
Ball Bearing Polygon Scanners
Ball bearing polygon scanners provide robust, high-speed scanning with proven reliability in industrial environments. Designed for durability and cost-efficiency, they deliver consistent performance at high throughput. Ideal for continuous operation with minimal maintenance requirements. Balance speed and practicality for scalable production systems.
Best for: High-throughput inspection, industrial processing, web applications
Key advantage: Speed
Compatibility: Laser systems, inline production equipment, industrial automation platforms
Overview
Engineered by Cambridge Technology, our ball bearing based polygon scanners provide a low-cost high precision raster scanner. Our ball bearing based polygon scanner is ideal for applications requiring less than 20,000 RPM which demand high load capacity and/or encoder feedback at a reasonable cost point. These scanners feature speeds ranging from 300 to 20,000 RPM available depending on polygon size, facet count, and scanner type.
Enhanced coatings
Enhanced aluminum and protected gold coatings covering wavelengths from 350 nm to 10,600 nm
Optional encoder
Optional encoder allows for improved positional feedback and better speed stability at slower speeds
Excellent power handling
Excellent power handling due to high rotation speeds and aluminum polygon substrates
High-speed raster scanning
Built for long lifetimes and high repeatability, our ball bearing polygon scanners are ideal for raster scanning applications such as high-speed inspection and sorting of a variety of agricultural commodities where large polygons, high performance, and consistent speeds are required.
