NSK and Its Commitment to Sustainability

In a significant move towards sustainability, NSK Ltd. has made headlines by releasing the industry's first-ever carbon footprint (CFP) report for ball screws. This report focuses on the low-friction ball screw named "MT-Frix™", developed for machine tools, and underscores NSK's dedication to fostering a carbon-neutral society.

Importance of CFP Disclosure

The carbon footprint serves as a quantifiable measure of greenhouse gas emissions per product unit, providing companies with an effective means to illustrate their environmental efforts. In recent years, the demand for environmental information across supply chains has surged, particularly in international markets like Europe. Disclosing carbon footprints not only showcases a product's environmental value but also enhances international competitiveness. Following this trend, Japan's Ministry of the Environment released the "Carbon Footprint Display Guide" in February 2025, prompting an acceleration in corporate disclosures.

The Journey of NSK’s CFP Report

From its manufacturing stages to consumer usage, NSK strives to reduce CO₂ emissions across the entire product lifecycle. The company emphasizes creating environmentally friendly products that significantly lower lifecycle environmental impacts.

Earlier, NSK developed a high-load capacity tapered roller bearing adaptable for construction machinery reconditioning, allowing the reuse of products and significantly reducing CO₂ emissions in the manufacturing process. This was followed by releasing the first CFP report in the bearing industry in July 2025. Now, with the ball screw segment, NSK's recent development of the "MT-Frix™" ball screw in October 2024 minimizes dynamic friction torque by 50%, leading to remarkable reductions in CO₂ emissions during usage. The release of this CFP report for the ball screw is a notable first in the industry.

Participation in EMO Hannover 2025

Following the rollout of "MT-Frix™", NSK will showcase this innovative product at EMO Hannover 2025, Europe’s largest machine tool exhibition, in September 2025. This exhibition targets a market with high demand for environmentally conscious products, highlighting NSK’s commitment to sustainability.
