NSK Linear Guides deliver exceptional precision accuracy combined with extremely high load ratings. Leveraging state-of-the-art advancements in ball groove geometry and ball circulation path design, load ratings and service life are dramatically increased—while maintaining smooth, quiet motion ideal for high-speed applications.
For more than 20 years, NSK has set the standard for long-term, maintenance-free lubrication in linear guides with the proven K1 lubrication unit. The next-generation K1-L raises performance even further, significantly extending maintenance intervals while reducing energy consumption and environmental impact.
Key enhancements include:
➡️ 1.8× longer lubrication life, enabled by a newly developed oil-supply material compared to conventional K1.
➡️ Up to 20% lower friction force, achieved through an improved rail-contact design for smoother, more efficient motion.
➡️ Enhanced oil retention and protection, with a redesigned K1-L casing that minimizes oil leakage and shields lubricated components from contamination and damage.
