Engineering Team
NSK specialized greases are custom-formulated for linear guides, ball screws and Monocarriers. Available in 8 types, each in an 80 g bellows tube with color-coding for easy identification. They cover general heavy-duty, high-speed, low-temperature, cleanroom and oscillating applications. Featuring stable formulations and consistent performance, they directly match the factory lubrication requirements of NSK equipment.
