Compact cross roller Gonio Bearings engineered for high-accuracy angular positioning in optical, metrology and semiconductor applications. Each set provides defined curvature geometry, the rotation axis remains constant throughout the travel range, preventing offset or parasitic movement. All components are matched per set and precision-ground. Factory measured parallelism and curvature guarantee sub-micron accuracy of motion. After preload they guarantee high repeatable accuracy of motion and consistent low friction resistance.
For dynamic or vertical applications, an optional Anti-Cage Creep (ACC) system prevents roller cage displacement during oscillating motion.
