THK Co., Ltd. NCF19267 Linear Motion Rail & Bearings

The THK NCF19267 Linear Motion Rail & Bearing Assembly is a precision guide system that pairs a hardened, precision-ground steel rail with a recirculating ball bearing carriage to deliver smooth, accurate, and low-friction linear motion. This model uses a recirculating ball linear guide (guide type) and a linear bearing block (carriage), with rail material and bearing material both hardened bearing steel, and precision recirculating steel balls for the rolling elements, ensuring high rigidity, high load capacity, and long service life. Designed for industrial automation and precision motion systems, it supports high-speed linear motion with low friction and corrosion-resistant surface finish, and is compatible with grease lubrication. The assembly is commonly installed in CNC machine tools, industrial robots, semiconductor processing equipment, automated assembly lines, packaging and labeling machinery, optical inspection systems, laboratory automation, and medical devices, and is used by maintenance teams, OEM machine builders, and system integrators for repairs, retrofits, and replacement of worn components. Common replacements include THK HSR, SHS, and SSR series.
