HGW-30-CC-ZOC / ZAC is a HIWIN size 30 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, ensuring smooth and precise linear motion. The ZOC (light preload) offers smoother movement, while ZAC (medium preload) provides greater rigidity and accuracy for demanding applications.
