THK SBN3210S-7WWG0916LC5 Ball Screw Drive Assembly

The THK SBN3210S-7WWG0916LC5 is a precision ball screw drive assembly engineered for servo-driven linear motion systems that demand high load capacity, minimal backlash, and smooth, repeatable travel. With a 32 mm screw diameter, 10 mm lead, and a 916 mm long screw shaft, this high-speed model delivers rapid, accurate positioning in CNC milling machines, machining centers, automated assembly equipment, robotics, semiconductor manufacturing equipment, packaging machinery, precision measuring systems, electronic manufacturing equipment, and material handling systems. It uses a single flanged ball nut, WWG ball circuit, and C5 accuracy, rated for 43.0 kN dynamic load and 73.1 kN static load, and it is grease-lubrication compatible with corrosion-protected THK surface finish for durability in demanding environments. Common replacements include THK SBN3210-7, SBNV3210-7, and BNF3210-7, making it a sensible choice for maintenance teams and system integrators performing repair, retrofit, expansion, or replacement of precision feed drive systems. The assembly features a high-speed design, high rigidity, and a low-backlash construction built on precision-ground ball screws.
