isoflex topas nb 5051

ISOFLEX TOPAS NB 5051 is a beige-colored, homogeneous, shortfibred long-term grease for a wide service temperature range. It is a dynamically light grease consisting of synthetic hydrocarbon oil and barium complex soap. The barium complex soap used is not classified as harmful under the EU Directives on dangerous substances.

ISOFLEX TOPAS NB 5051 ensures low starting and running torques. In addition, it is resistant to oxidation and ageing, and protects reliably against corrosion.

  • ISOFLEX TOPAS NB 5051 is used for plain and rolling bearings (e.g. in automotive engineering) and for gas meters. It is also used in small gears, where it reduces the noise produced by the gear wheels.
  • ISOFLEX TOPAS NB 5051 is also suitable for the lubrication of tooth flanks in precision gears (e.g. bevel gears in milling machines, electromechanical actuators for valves).
  • Its good adhesion on smooth surfaces makes it ideal for the runningin lubrication (assembly) of plastic and composite bearings.
  • Synthetic long-term lubricating grease for a wide service temperature range
  • Low starting and running torque
  • Good wear protection
  • Good corrosion protection
  • Resistant to oxidation and ageing
