Areas of application

  • Lubrication of rolling and friction bearings at operating temperatures around +170°C up to rotating speed limit
  • For example, smaller bearings of exhaust-gas turbochargers, hot-air fans, hot-water pumps, washing machines and laundry dryers, as well as clutch pressure and release bearings etc.
  • Also suitable for plastic/plastic sliding pairs

Advantages and benefits

  • Highly effective due to optimum temperature-stable silicone grease formula
  • Excellently suited for grease lubricating points subject to changing temperature loads
  • Broad range of uses outside normal grease performance areas

Technical specifications

  • lower operating temperature: -40 °C
  • upper operating temperature: 200 °C
  • consistency: 2 NLGI grade (DIN ISO 2137)
  • viscosity at (25°C): 125 mm²/s (base oil)
  • four-ball test rig welding load: 1,100 N


For best results, clean lubricant points and surfaces carefully, e.g. with OKS 2610 or 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, high-speed bearings (DN value > 400,000) up to about 1/4. 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. Bearings filled with silicon grease must not have higher loads than 1/3rd of the bearing´s permitted load. Silicone-based plastics, e.g. silicone rubber, can be dissolved by silicone grease. Silicone grease must not be applied to sliding surfaces under influence of pure oxygen.
