Working Theory
Ball linear guides operate via a recirculating ball mechanism. The carriage houses multiple rows of high-grade steel balls that roll along precision-machined raceways on the rail. As the carriage moves, the balls continuously cycle through return channels, ensuring consistent contact and load distribution. Preload adjustments compress the balls slightly against the raceways, removing internal clearance to enhance stiffness and positional accuracy. Integrated wipers and grease retainers prevent contaminant ingress, while lubrication grooves ensure even oil distribution.
