Areas of application

  • For highest contact pressure and high circumferential speed, e.g. for rotary kilns, ball mills, rotary barrel mixers, ball mills, rope winches or friction presses also for guiding elements, slide bars, heavy transport chains and closed wire ropes
  • Lubrication of rotating assemblies of convertors, cranes, crushers and dredges with spray or central lubricating systems
  • Lubrication of heavily loaded gear couplings

Advantages and benefits

  • Most suitable for reliable supply of open gears, even at high circumferential speed
  • Very efficient through EP additives in association with a specific combination of solid lubricants and adhesive additives
  • Reliable protection of tooth flanks, even at high temperatures and with extended relubrication time
  • Good pressure resistance of the lubricating film, excellent wear protection
  • The film is not embrittling and aging. Without bitumen, solvent, does not contain heavy metals

Technical specifications

  • lower operating temperature: -30 °C (lubricating film)
  • upper operating temperature: 220 °C (at relubrication)
  • consistency: 0 NLGI grade (DIN ISO 2137)
  • viscosity at (40°C): 1,000 mm²/s (base oil)
  • four-ball test rig welding load: approx. 6,500 N
  • FZG wear protection test: > 12 power level (A2/76/50)


For best results clean the sliding surfaces carefully, e.g. with OKS 2610/OKS 2611 Universal Cleaner. For lubrication with spray lubricating systems, with a brush or a spatula. Instructions of the gear or machine manufacturer should be observed. Relubrication periods and amount should be defined according to the operating conditions. Avoid overfeeding. Only mix with appropriate lubricants.
