Klüber ISOFLEX TOPAS NB 52 Synthetic Bearing Grease
004131
Overview
ISOFLEX TOPAS NB 52 is a rolling and plain bearing grease based on a synthetic hydrocarbon oil and a barium complex soap. The special barium-soap thickener offers good load-carrying capacity as well as resistance to water and ambient media, with good corrosion protection and oxidation and ageing stability. It is suitable for -50°C to 120°C with short peaks up to 150°C, and is also used on tooth flanks of precision gears and on electric contacts to reduce insertion forces.
