The THK FBL35S P13 SERIES represents a specialized single slide rail solution engineered for light load applications where precision, compact design, and reliable linear motion are paramount. This model features a 35mm rail width and a standardized P13 pitch for mounting holes, ensuring compatibility and ease of integration into diverse mechanical systems. Constructed with high-carbon chromium bearing steel, the rail and block are subjected to rigorous heat treatment processes to achieve a surface hardness of approximately HRC 58-64, providing exceptional resistance to wear and deformation under operational stresses. The incorporation of THK’s proprietary Caged Ball technology is a defining feature, where precision steel balls are retained within a resin cage. This design minimizes friction, eliminates ball-to-ball contact, and significantly reduces noise and vibration during movement, while also allowing for smoother motion at high speeds and enhancing overall service life by preventing lubricant starvation.

Performance advantages of the FBL35S P13 SERIES are substantial, beginning with its ability to maintain high positional accuracy and repeatability, critical for applications demanding micron-level precision. The low friction coefficient, achieved through optimized ball recirculation and optional pre-load adjustments, results in reduced driving force requirements, enabling the use of smaller, more energy-efficient motors and drives. This contributes to lower operational costs and heat generation. The series supports high-speed travel up to 2 m/s and accelerations of 15 m/s², making it suitable for dynamic applications. Its sealed design, featuring integrated scrapers and end seals, effectively excludes contaminants like dust, chips, and moisture, ensuring reliable performance in harsh environments without frequent maintenance. Additionally, the compact and lightweight structure allows for space-saving installations without compromising load capacity, which includes a dynamic load rating of 6.8 kN and a static load rating of 10.2 kN, facilitating stable operation under moment loads.

Typical applications span multiple industries, leveraging the series’ precision and durability. In industrial machinery, it is commonly deployed in automated assembly lines, pick-and-place robots, and precision measuring instruments, where smooth, accurate linear motion is essential for throughput and quality control. Within automotive systems, the FBL35S P13 SERIES finds use in welding equipment, component testing jigs, and dashboard assembly mechanisms, benefiting from its resistance to vibration and contaminants. In precision equipment, such as semiconductor manufacturing tools, medical devices, and optical positioning systems, its low particle generation and high-speed capabilities ensure clean, reliable operation critical to sensitive processes. Overall, the THK FBL35S P13 SERIES delivers a balanced combination of technical sophistication, performance efficiency, and application versatility, making it an ideal choice for engineers seeking to optimize light load linear motion in demanding environments.
