Used in

Common applications for NB

Industrial automation — NB Alulin series guide rails (e.g., A20-760mm) used in pick-and-place gantries for lightweight, high-speed linear motion.

Packaging machinery — NB ball spline shafts (e.g., SSP8S-500mm) in rotary indexing tables for precise torque transmission and linear movement.

Semiconductor manufacturing — NB stainless steel ball spline shafts (e.g., SSP6S-150mm) in wafer handling robots for corrosion resistance and precision.

Medical device assembly — NB Alulin series runner blocks (e.g., GNS-1500) in diagnostic equipment for smooth, low-friction linear positioning.

CNC machine tools — NB ball spline nuts (e.g., SSPF 10) in tool changers for reliable linear actuation under load.

Printing equipment — NB Alulin series guide rails (e.g., A20-4000mm) in large-format printers for long-stroke, lightweight linear guidance.
