Frequently Asked Questions
Q: What applications is Klüber ISOFLEX NCA designed for?
Klüber ISOFLEX NCA is engineered for Low-temperature bearings. The product is commonly specified in industries including Low-temperature bearings, instrument bearings, precision equipment, aircraft components, cold storage equipment and related industrial sectors where reliable lubrication is critical.
Q: What temperature range does it operate in?
The operating temperature range is -50°C to +120°C. Always verify the specific temperature requirements for your application against the product datasheet to ensure compatibility.
Q: Is Klüber ISOFLEX NCA food grade?
No, Klüber ISOFLEX NCA is not NSF H1 registered for food-grade applications. For food processing environments requiring NSF H1 certification, consider Klüberfood NH1 or Klubersynth UH1 product series.
Q: Can this product be mixed with other greases?
As a general engineering practice, mixing greases with different thickener types is not recommended. Incompatible thickeners can cause the grease to soften excessively or harden, potentially leading to lubrication failure. If switching from another product, it is best practice to thoroughly purge the old lubricant before applying the new one.
Q: How should this product be stored?
Store in original sealed container at 0°C to 40°C. Protect from moisture contact and freezing of opened containers. The typical shelf life is 36 months from date of manufacture under recommended storage conditions from the date of manufacture under recommended storage conditions.
