HGW-15-CC-ZOC / ZAC is a HIWIN size 15 flange-type (W series) linear guide block designed for CNC and automation applications. It offers wide mounting (C type) for better stability and higher moment load capacity. The block ensures smooth, low-friction linear motion using recirculating ball technology. The ZOC (light preload) provides smoother movement, while ZAC (medium preload) offers higher rigidity and precision for demanding applications.
