For precision equipment, the LSP SERIES is deployed in semiconductor manufacturing apparatus, optical positioning stages, precision measuring instruments, and medical automation devices where clean, accurate, and reliable linear motion is paramount. Its robust and sealed construction makes it a dependable choice for these high-performance, mission-critical applications.

The THK Linear Ball Slide Without Rack Model LS SERIES represents a fundamental advancement in compact linear motion technology, engineered for applications where space is at a premium but high performance is non-negotiable. This series is characterized by its integrated slide unit construction, which combines a rigid base, precision-ground guideways, and a compact slide block into a single, highly rigid unit. The core of its motion is facilitated by a precision-circulating ball bearing system. As the slide block moves along the guideways, the balls recirculate endlessly within the compact block, providing smooth, low-friction linear motion with minimal resistance and excellent positional accuracy. Several key technical features define the LS SERIES's performance envelope. Its compact, low-profile design is a primary characteristic, offering a significant reduction in mounting space and overall height compared to traditional slide systems, making it ideal for machinery with stringent size constraints. The incorporation of high-capacity, long-length balls within the recirculating system ensures a substantial load rating, allowing the unit to handle significant moment loads and forces in multiple directions. Furthermore, the guide rails are precision-ground from high-carbon chromium bearing steel and subjected to rigorous heat treatment, resulting in exceptional surface hardness, wear resistance, and long-term dimensional stability. This robust construction is complemented by optional seals and wipers that effectively shield the precision ball tracks from contaminants like dust and chips, thereby enhancing service life and reliability in demanding environments. The performance advantages of this design translate directly into operational benefits for machinery designers and operators. The low-friction ball circulation mechanism yields exceptionally smooth and quiet motion, which minimizes vibration and contributes to higher quality surface finishes in machining applications. This smooth operation, combined with high rigidity, ensures outstanding positional accuracy and repeatability, which is critical for precision assembly and inspection tasks. The high load capacity and rigidity also contribute to a long, maintenance-free service life, reducing total cost of ownership. The simplicity of its design allows for easy installation and integration, as the unit is supplied as a complete, pre-assembled system that requires no complex alignment or adjustment. Typical applications for the THK LS SERIES are found across a spectrum of industries that demand reliable, precise, and compact linear motion.
