ISOFLEX TOPAS NB 52

1kg - R.R.P - £690.00 + VAT

Synthetic long-term grease

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.
Content: 1kg can
Available in 370g cartridge , 1kg can, 25kg bucket

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.
