Ball-rail systems

Star ball-rail systems are for machine tools and industrial robots needing rolling-element linear guides. The systems from Rexroth Star, Charlotte, N.C., are available in up to five accuracy and four preload classes, each with high load-carrying capacity and rigidity. The compact systems come in eight industry-standard sizes and offer the same load rating in all four main-load directions. Individual components can be replaced at any time.
