Introduction to NSK Linear Guides – LH/LS Series Updated to NH/NS Series

Extended Service Life: Compared to the older LH and LS series, the NH/NS series achieves double the service life. The rated load capacity is increased by 1.3 times, resulting in twice the lifespan.

Maintenance-Free Operation: Equipped with the NSK K1 lubrication unit, the NH/NS series ensures long-term maintenance-free performance. This not only reduces operational costs but also contributes to environmental sustainability.

Standardization and Interchangeability: The NH/NS series offers easy-to-use standard linear guides and includes Random Matching types that allow free combination of blocks and rails. This interchangeability helps meet diverse application needs and shortens delivery lead time.

High Tolerance for Mounting Errors: The NH/NS series adopts a DF (Double Face) combination structure similar to that used in rotary bearings, allowing it to tolerate greater mounting misalignments and reducing installation burden.

Diverse Options: A variety of optional features are available, including NSK K1 lubrication units, double seals, end caps, and surface treatments, to meet specific customer requirements.

Compatibility with LH/LS Series: The NH series retains the same installation dimensions as the LH series, and the NS series matches the LS series, allowing for easy replacement without mechanical design changes.

Optimized Ball Groove Design for Longevity: Leveraging NSK's latest friction and analytical technologies, the NH/NS series features a new groove design that optimizes contact surface pressure distribution, significantly extending rated life.

High-Speed Performance: Featuring an advanced ball circulation system, the NSK NH/NS series ensures smooth circulation and reduced noise, making it more suitable for high-speed applications compared to the LH/LS series.

Precision and Preload Options: The NH/NS series is available in various precision grades and preload specifications to meet the demands of different applications.
