LG Series
Ball Linear Guideway
Standard-duty ball-type design delivering reliable performance at an accessible price point. The cost-effective choice for light to medium duty CNC, 3D printers, and general automation.
LG Series Ball Linear Guideway
The LG Series is Luoyang Songju's standard-duty ball linear guideway, optimized for applications where proven reliability meets budget-conscious procurement. Maintaining the core engineering principles of the premium LGS line -- hardened steel raceways, precision-ground ball tracks, and multi-lip sealing -- the LG Series delivers consistent, smooth linear motion for light to medium duty applications without the premium features required only in heavy industrial settings.
Available in rail widths from 15mm to 45mm with precision grades H and P, the LG Series covers the sweet spot of light CNC machines, 3D printers, pick-and-place automation, laboratory equipment, and general linear positioning tasks. Preload options allow engineers to dial in the right balance of rigidity and friction for each specific application. The cost-effective design does not compromise on manufacturing quality -- each LG guideway is produced on the same precision grinding equipment and inspected to the same rigorous standards as Luoyang Songju's full product line.
