Minimize Linear Bearing Downtime with NSK K1™ Lubrication Units

A metal pipe manufacturer was facing frequent downtime caused by linear bearing failures on its Nakata saw. Contamination led to two breakdowns per year, disrupting maintenance schedules, cutting production, and eroding profits.

NSK industry specialists evaluated the situation through our AIP Asset Improvement Program and recommended NSK Linear Guides paired with the patented K1™ Lubrication Units. The self‑lubricating K1™ system not only supplies continuous grease but also serves as a robust contaminant barrier, preventing dirty material from entering the carriage.

After installing the K1™ units on the NSK Linear Guides, the mill operated the Nakata saw uninterrupted for over two years—no bearing replacement needed. The solution delivered an estimated $5,684,000 in savings, covering downtime, maintenance, and lost production.

The K1™ Lubrication Unit is ideal for environments where grease replenishment is impractical or where grease is prone to washout. It offers long‑term, maintenance‑free performance in any mounting orientation and is available for standard NSK linear guides, ball screws, Monocarrier™ actuators, and robot modules. An FDA‑compliant variant can be requested.

Through innovations like the K1™ Lubrication Unit, NSK helps customers boost productivity, cut costs, and extend component life. To learn more about the benefits of AIP, visit our website.
