G+ GSN Series

Tags: gear, precison gear, hollowgear, arcmin, arcsec

The GSN series features high-precision repeatability positioning and a large-diameter hollow structure for easy wiring and piping. It supports horizontal, suspended, and side mounting options, with clear model compatibility for different scenarios: GSN60 is suitable for precision small-load worktables; GSN85 is suitable for small to medium-sized robotic arms; GSN130 can be used for medium-sized assembly line rotary tables; GSN200 is suitable for heavy-duty robotic arms; GSN280 is suitable for large production line workstations; and GSN450 can be customized in installation size and is suitable for ultra-large load transfer platforms.
