HGW-20-CC-ZOC / ZAC is a HIWIN size 20 flange-type (W series) linear guide block designed for CNC and industrial automation applications. It features a wide mounting design (CC type) for higher stability and load capacity, with smooth and precise linear motion using ball recirculation. The ZOC (light preload) ensures smoother movement, while ZAC (medium preload) provides increased rigidity and accuracy for demanding applications.
