NTN Ball Screw Production Expansion Targets Eightfold Capacity by FY2030

NTN Corporation is advancing its long-term manufacturing strategy by establishing a stronger global supply network for ball screws, a key mechanical component that converts rotational motion into linear motion. The company is evaluating the start of mass production at an NTN Group manufacturing facility in Southeast Asia as early as fiscal year 2028, which ends on March 31, 2029. This initiative is designed to strengthen production capabilities while preparing to meet increasing worldwide demand from brake manufacturers and other automotive customers as vehicle electrification continues to expand.

The proposed manufacturing facility in Southeast Asia would operate alongside the Japan-based Iwata Works, creating a dual-production system capable of supporting customers across multiple regions. By distributing production between these two locations, NTN Corporation aims to improve supply flexibility, strengthen delivery performance, and respond more efficiently to future increases in global demand for ball screw applications used in modern vehicle systems.

NTN has established an ambitious production roadmap, targeting an increase in ball screw manufacturing capacity to approximately eight times its fiscal year 2024 level by fiscal year 2030. The company expects this capacity expansion to support both domestic and international brake manufacturers while ensuring sufficient supply for future automotive applications requiring highly precise linear motion components.

Demand for hybrid vehicle components is expected to remain strong as collision-mitigation braking systems become increasingly mandatory across global markets. At the same time, NTN projects that the transition toward electric vehicles will accelerate demand for ball screws even more rapidly. These market trends are encouraging the company to strengthen its manufacturing footprint and prepare for sustained growth across multiple vehicle electrification segments.

While executing its expansion strategy, NTN will continue monitoring competitive developments involving emerging manufacturers from China. The company intends to expand its global supply capabilities while closely observing changes in the competitive landscape, enabling it to respond effectively as worldwide demand for electrified vehicle components continues to evolve.
