Ultra-compact crossed roller guide featuring alternating orthogonal rollers for multi-directional rigidity. The LGC4B series achieves ±0.5μm/m positioning repeatability through mirror-finished raceways and precision-ground rollers. Integrated sealing comb structures prevent particulate ingress while maintaining smooth motion characteristics.
