This product line is a complete screw-and-guide transmission solution developed by Nanjing
Gongyi for high-speed precision machine tools, including precision grinding machines, 5-axis
machining centers, horizontal/vertical machining centers, profile machining centers, and
drilling/tapping centers. Ball screw assemblies and rolling linear guideways are supplied as a
matched set, eliminating the need for separate selection, matching, and commissioning—one
solution, one delivery, one-stop integration.
The range is fully standardized: screw nominal diameters from Φ28 to Φ63 mm, leads of
12/16/18/20/25 mm; paired guideway sizes GZB35, GZB45, GZB55, GZB65; both screw and
nut can be configured with hollow-shaft forced-cooling construction to control thermal
deformation under high-speed, high-precision operation. We already supply V8, 850, 855, 1160,
T6, T7 and other mainstream models in volume, with ready stock available.
