The THK Linear Guide series features Caged Ball Technology that separates each ball individually, eliminating ball-to-ball friction and dramatically extending service life while reducing noise and heat generation. The unique ball cage retains lubrication within the carriage for extended maintenance intervals. The four-row ball arrangement provides high load capacity and rigidity. Widely used in high-end CNC machine tools, semiconductor lithography stages, aerospace test equipment, and precision optical instrument slides.
