The THK Slide Pack Model FBW50110XR SERIES represents a fully integrated linear motion solution engineered for high-load capacity and exceptional rigidity in demanding industrial environments. This complete assembly combines THK’s precision FBW Series linear motion guides with a matched slide unit, pre-assembled and adjusted at the factory to ensure optimal performance and immediate operational readiness upon installation. The system is built around a compact, cross-roller-based design where precision-ground rollers circulate between V-grooved raceways on the rail and block, providing a robust and highly accurate guiding mechanism.

Key technical features define the series’ capability. The FBW50110XR utilizes a large roller diameter and a high-rigidity, sealed end cap structure to withstand significant moment loads and impact forces. Its compact height and width profile allow for space-saving machine designs without compromising on load-bearing performance. The integrated seals and wipers are highly effective at excluding contaminants like dust, chips, and splashing liquids, while simultaneously retaining the high-performance grease packed at the factory for long-term lubrication. This pre-lubrication and sealing make the unit maintenance-free for extended periods under normal operating conditions. The series is characterized by its high running accuracy, smooth motion with minimal friction fluctuation, and excellent positional reproducibility.

The performance advantages derived from this design translate directly into operational benefits. The high static and dynamic load ratings enable the handling of heavier workpieces or the application of greater machining forces, enhancing process capability. The exceptional rigidity minimizes deflection under load, which is critical for maintaining precision in machining, measuring, and assembly applications. The low friction and high efficiency of the roller-based system contribute to reduced drive power requirements and smoother velocity control. Furthermore, the maintenance-free nature of the sealed and pre-lubricated pack significantly reduces total cost of ownership by eliminating downtime for re-lubrication and preventing premature failure from contamination.

Typical applications for the THK FBW50110XR SERIES are found across industries where reliability, precision, and high load capacity are paramount. In industrial machinery, it is ideally suited for the vertical axes of CNC machining centers, heavy-duty grinding machines, and the precise positioning stages of semiconductor and LCD manufacturing equipment. Within automotive production systems, these slide packs are deployed in robotic welding and handling units, precision press-feeding mechanisms, and automated inspection stations. In the realm of precision equipment, they provide the stable and accurate linear motion required for coordinate measuring machines (CMMs), optical alignment systems, and advanced medical diagnostic devices, ensuring consistent performance in critical, high-value processes.
