Product Description
ZOTIK-FT Flat Needle Roller Linear Cage is designed for high-precision linear motion applications requiring high load capacity, smooth movement, and stable positioning.
Unlike right-angle HW cage designs, the FT series uses a flat cage structure, making it suitable for installation on flat guideways and precision sliding surfaces.
The cage frame is manufactured from aluminum alloy, while the rolling elements are made from bearing steel needle rollers. This structure provides high rigidity, excellent wear resistance, high load capacity, and accurate linear motion.
