SRG-GSLC SERIES

THK’s LM Guide SRG-G/SRG-GSLC Series represents a significant advancement in linear motion technology through its full roller type design, delivering ultra-high rigidity for the most demanding industrial applications. This series employs cylindrical rollers arranged in a full complement configuration within the raceway, maximizing contact area and load distribution. The SRG-G models feature a standard design, while the SRG-GSLC variants incorporate a sealed and lubricated unit, pre-packed with grease and equipped with specialized seals to prevent contamination and extend maintenance intervals. Both are engineered to withstand extreme loads, shock, and vibration while maintaining precise linear guidance.

Key technical features include a rigid steel construction with precision-ground raceways, ensuring smooth roller movement and minimal deformation under stress. The full roller arrangement eliminates ball-based limitations, providing higher load capacities—up to twice that of equivalent ball guide models—and enhanced moment rigidity. The SRG-GSLC’s integrated seals effectively block dust, chips, and other particulates, while the pre-lubrication system reduces friction and wear. Additionally, the series offers easy installation with reference surfaces for alignment and standardized mounting hole patterns, simplifying integration into machinery.

Performance advantages are substantial, starting with exceptional accuracy and repeatability due to reduced elastic deformation. The ultra-high rigidity minimizes deflection during operation, critical for applications requiring tight tolerances. Low noise and vibration levels contribute to smoother motion, while the high-speed capability—supported by the roller design—ensures efficient cycle times. The SRG-GSLC’s maintenance-friendly design lowers total cost of ownership by reducing lubrication frequency and preventing premature failure from environmental contaminants.

Typical applications span industries where reliability under heavy loads and precision are non-negotiable. In industrial machinery, the SRG-G/SRG-GSLC Series is ideal for heavy-duty CNC machining centers, transfer lines, and press feeds, where it supports high thrust forces and maintains alignment in multi-axis systems. Automotive manufacturing leverages these guides in robotic welding arms, assembly robots, and automated material handling equipment, enduring continuous operation and shock loads. Precision equipment applications include semiconductor manufacturing devices, optical positioning stages, and measuring instruments, where minimal vibration and sub-micron accuracy are essential. The series’ robustness also suits injection molding machines, packaging machinery, and aerospace testing rigs, demonstrating versatility across sectors that demand durability, precision, and long service life.
