Areas of application

  • For closed gear units and geared motors, plain and friction bearings even at higher rotating speeds, e.g. on filling and packaging machines
  • For joints, propeller shafts and chains when grease lubrication is specified

Advantages and benefits

  • Toxicologically harmless as defined in German LFGB
  • Formula in accordance the FDA guideline 21 CFR 178.3570
  • NSF H1 registered
  • Long operating times due to good resistance to oxidation and ageing
  • Reduced wear due to highly adhesive, load-bearing lubricating film
  • Excellent corrosion protection
  • Low dynamic viscosity enables use with minimal bearing play and gear unit spaces
  • Good pumpability with central lubricating systems
  • Very high resistance to hot and cold water, watery-alkaline and acidic disinfectants and cleaning agents

Technical specifications

  • lower operating temperature: -45 °C
  • upper operating temperature: 120 °C
  • consistency: 0-00 NLGI grade (DIN ISO 2137)
  • viscosity at (40°C): 160 mm²/s (base oil)


For best results clean the lubricating point carefully, e.g. with OKS 2610/OKS 2611 Universal Cleaner. Remove the corrosion protection ahead of the initial filling. Fill gears in a way that all the functional surfaces for sure transport the grease. Fill bearings in a way that all the functional surfaces for sure get the grease. Observe the instructions of the gear- bearing or machine manufacturer. Relubrication with automatic lubrication system or with a brush or spatula. Relubrication intervals and amount to be defined acc. to the service conditions. If the removal of the old grease is not possible the amount of grease has to be limited to avoid excess lubrication of the bearing. At longer relubrication intervals a complete exchange of the old grease is recommended. Only mix with appropriate lubricants.
