The THK LM Guide LM Guide (full ball type) Miniature Model SRS G SRS5WGN SERIES represents a compact, high-precision linear motion solution engineered for applications where space constraints and demanding performance criteria converge. This series incorporates a full-ball type design, where the entire circumference of the shaft is utilized as a raceway, enabling the carriage to support loads from all directions—radial, reverse-radial, and lateral. This fundamental architecture is the cornerstone of its exceptional rigidity and moment load capacity, even within its miniature form factor. The SRS5WGN model specifically features a stainless steel (SUS440) shaft with a resin end seal, providing inherent corrosion resistance and effective protection against contaminants in challenging environments.

Technically, the SRS G series is distinguished by its optimized ball groove profile and precision-ground components, which work in unison to deliver smooth, near-silent motion with exceptionally low friction and high positional accuracy. The incorporation of a full-complement ball arrangement, without a ball retainer, maximizes the number of load-carrying balls in contact with the raceways. This design significantly increases load capacity and stiffness while simultaneously distributing wear over a greater number of contact points, leading to a dramatically extended service life and consistent performance over time. The compact carriage design minimizes the overall mounting space required, making it an ideal drop-in replacement or new design component for miniaturized machinery.

The performance advantages of the SRS5WGN SERIES are substantial. Its high rigidity translates into minimal deflection under load, which is critical for maintaining precision in machining and assembly operations. The low coefficient of friction ensures high efficiency, reducing drive power requirements and minimizing heat generation. Furthermore, the sealed design, often enhanced with optional grease fittings for easy re-lubrication, ensures long-term reliability and reduces maintenance intervals, even in environments with fine dust, chips, or occasional liquid splash.

Typical applications for this miniature LM Guide are found across industries that demand precision and reliability in a small package. In industrial automation, it is extensively used in the linear axes of compact pick-and-place robots, precision assembly machines, and the sliding stages of semiconductor and electronic component manufacturing equipment. Within the automotive sector, it finds purpose in precision sensors, advanced headlight leveling mechanisms, and small-scale testing and measurement apparatus. For broader precision equipment, the SRS5WGN is a critical component in medical devices such as DNA analyzers and lab automation systems, optical positioning stages, and high-accuracy coordinate measuring machines (CMM) probes, where its compact size, high stiffness, and smooth motion are indispensable for achieving micron-level accuracy.
