Areas of application

  • For lubricating rolling and friction bearings at high temperatures, under high stress loads and in damp environments, such as hot air fans, converters, casting pans, sintering plants, and conveying systems exposed to heat in the iron and steel industry Long-life lubrication of excavating and construction machines in humid environments

Advantages and benefits

  • Prolonged component life span thanks to effective wear protection and excellent pressure absorption capacity
  • Reliable protection for bearings in humid environments due to effective corrosion protection in combination with effective adhesion and resistance to water
  • Optimum supply to bearings thanks to excellent dispensing capacity, even at high temperatures, without the grease solidifying in the lubrication lines
  • Environmentally friendly formula with no chlorine or heavy metals

Technical specifications

  • lower operating temperature: -15 °C (≤ 1,400 hPa)
  • upper operating temperature: 150 °C (F50 (A/1500/600), 100h)
  • consistency: 2 NLGI grade (DIN ISO 2137)
  • viscosity at (40°C): 500 mm²/s (base oil)
  • four-ball test rig welding load: 2,800 N


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 the bearings in a way that all the functional surfaces for sure get the grease. Slow moving bearings (DN-value < 50,000) should be filled completely, normal moving bearings should be filled to 1/3 of the free inner housing space. Observe the instructions of the bearing or machine manufacturer. Relubrication with a grease gun on to the grease nipples or with an automatic lubrication system. 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.
