Klüber ISOFLEX NCA 15
Spindle bearing grease
Application Klüber ISOFLEX NCA 15
ISOFLEX NCA 15 is particularly suitable for the lubrication of spindle and tapered roller bearings, threaded spindles, ball screws subject to high loads, and for all high-speed bearings, e.g. bearings in OE-spinning turbines used in the textile industry.
Performance, Features & Benefits of Klüber ISOFLEX NCA 15 are:
- Longer rolling bearing life due to good wear protection, water resistance and pressure absorption capacity
- Tried and tested over many years especially in high-speed and low-temperature applications
- Low heating-up of bearings due to low lubricant friction leading to longer service life
- Low running torque enables energy savings, particularly at low temperatures, hence costs savings possible

Application notes
The lubricant is applied by brush, spatula, grease gun or grease cartridge. Owing to the different compositions of elastomers and plastic materials, compatibility tests are indispensable before series application.
