Klüber Isoflex Topas NB 152 Synthetic rolling plain bearing grease 1kg

ISOFLEX TOPAS NB 52 and ISOFLEX TOPAS NB 152 are rolling and plain bearing greases based on a synthetic hydrocarbon oil and a barium complex soap. The special barium-soap thickener used in the ISOFLEX TOPAS NB 52 and 152 greases offers good load-carrying capacity as well as resistance to water and ambient media unlike other soap-based thickeners. Both products show good protection against corrosion as well as oxidation and ageing stability. The Klüber barium complex soap is ELINCS-registered and approved by GASG (Global Automotive Stakeholders Group).

ISOFLEX TOPAS NB52 is suitable for temperatures between -50 °C to 120 °C and short peak temperatures up to 150 °C depending on the application, e.g. enclosed gears, car seat adjustment mechanisms.

Benefits for your application:

• Longer component life when exposed to water or aqueous media due to special thickener
• Many years of successful use in the automotive and machine building industries

Application:
ISOFLEX TOPAS NB 52 is a versatile grease for many applications, e.g.

• Rolling and plain bearings subject to high speeds and loads, also for low temperatures,
• Tooth flanks in precision gears, e.g. bevel gears in milling machines, electromechanical actuators for valves,
• Electric contacts and components to reduce insertion forces.

Application notes:
The greases are applied by spatula, brush, grease gun or cartridge. Sprays should not be exposed to direct sunlight and temperatures above 50 °C.
