HGW-25-CC-ZOC / ZAC is a HIWIN size 25 flange-type (W series) linear guide block designed for CNC and industrial automation. 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) offers smoother movement, while ZAC (medium preload) provides higher rigidity and accuracy.
