Kluber ISOFLEX TOPAS NCA 52 is a premium, fully synthetic high-performance bearing grease designed for long-term lubrication of rolling and plain bearings operating under demanding conditions. It is especially suited for applications requiring low friction, excellent ageing resistance, and reliable performance over a wide temperature range.
Formulated with synthetic hydrocarbon oil and a polyurea thickener, ISOFLEX TOPAS NCA 52 offers outstanding oxidation stability, very low oil separation, and excellent wear protection. This makes it ideal for electric motors, high-speed bearings, precision machinery, and industrial drive systems where extended relubrication intervals are required.
The cartridge comes factory-filled with Klüber grease, ensuring correct quantity and cleanliness. The “Star” design refers to Klüber’s cartridge system that is specifically made for use with their automatic lubricators and central lubrication units. The 120 cm feed line allows the lubricator to be mounted away from the actual bearing or lubrication point, which is useful when access is limited, when the lubrication point is in a hazardous or high-temperature area, or when vibration makes direct mounting unsuitable.
This type of cartridge helps ensure consistent, precise grease delivery over time, reduces the risk of contamination during handling, and simplifies maintenance by allowing quick, clean cartridge replacement. It is commonly used in industrial machinery, motors, fans, conveyors, pumps, and other equipment that benefits from automated lubrication.
