LGSW Series
Wide-Type Rolling Linear Guideway
Engineered for high moment capacity in single-rail applications. Wider rail cross-section and bolt pattern dramatically increase allowable overturning moment, enabling cost-effective single-rail configurations.
LGSW Series Wide-Type Rolling Linear Guideway
The LGSW Series is Luoyang Songju's wide-type linear guideway, engineered for applications where a single rail must support significant moment loads that would overwhelm a standard-width guideway. By increasing the rail width and widening the bolt pattern, the LGSW dramatically increases the allowable overturning moment capacity. This enables single-rail configurations that eliminate the cost, alignment complexity, and space requirements of parallel rail installations.
Built on the proven 4-row recirculating ball architecture of the LGS Series, LGSW guideways share the same ball contact geometry, seal design, and manufacturing standards while extending the footprint for enhanced stability. The wider rail cross-section also provides a larger heat dissipation area, enabling higher duty cycles in high-speed cantilever applications. Available in rail widths from 20mm to 65mm in precision grades P and H, LGSW guideways are the definitive solution for cantilever axes, single-rail gantries, and compact machine designs where space precludes dual-rail setups.

Why Choose LGSW Wide-Type Guideways
The LGSW Series eliminates the need for parallel rail installations in moment-loaded applications, reducing cost, complexity, and alignment time.
High Moment Capacity
Wider rail cross-section and bolt pattern dramatically increase overturning moment resistance, enabling single-rail designs where dual rails were previously required.
Single-Rail Solution
Eliminate the cost, alignment complexity, and space requirements of parallel rail installations. One LGSW rail does the work of two standard rails in moment-critical axes.
4-Row Ball Design
Proven recirculating ball architecture with four independent ball circuits provides equal load capacity in all directions for consistent multi-axis performance.
Wide Bolt Pattern
Extended bolt spacing provides a larger mounting footprint, increasing structural stiffness at the rail-to-base interface and reducing deflection under moment loading.
Enhanced Heat Dissipation
The wider rail cross-section provides a larger surface area for convective heat dissipation, enabling higher duty cycles in high-speed cantilever applications.
Standard LGS Compatibility
Shares ball contact geometry, seal design, and manufacturing standards with the LGS Series, ensuring consistent quality and simplified spare parts management.
