OKS 475 – High-Performance Grease

Fully synthetic high-performance grease with PTFE for use at low temperatures and high speeds.

Areas of application

  • Grease lubrication of plain and roller bearings with low bearing play as well as bearings with low coasting moments
  • Lubrication for fast-running roller bearings
  • Sealing lubrication of mating surfaces, for example ground-in parts such as taper plugs, dosing plungers and valves
  • Maintenance lubrication of plastic and rubber parts with embrittlement protection and good frictional characteristics, particularly on metal surfaces

Advantages and benefits

  • Temperature range from -60°C to 120°C
  • Resistant to all alkali and acid cleaning agents and disinfectants
  • Good wear protection through PTFE
  • NSF H2 registration

Technical specifications

  • Operating temperature: -60°C → +120°C
  • NLGI grade: 2
  • DN factor (dm x n): 1,000,000 mm/min
  • Base oil viscosity (40°C): approx. 30 mm²/s
  • Four-ball test rig (welding load): 2,000 N

Applications

Clean the lubricating points well for optimal effect. Before filling for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill normal bearings up to about 1/3 of the free space inside the bearing, high-speed bearings (DN value < 400,000) up to about 1/4. Low-speed bearings (DN value > 50,000) and their housings should be filled completely. In as far as available, the bearing and machine manufacturer's instructions should be observed. Subsequent lubrication at the lubrication nipples by grease gun or by automatic lubrication system. Assess the lubrication frequency and quantity on the basis of the service conditions. If old grease cannot be removed, restrict the quantity of grease so as to avoid over-lubricating the bearing. If lubrication frequencies tend to be low, you should aim for a full grease change. Caution: Only mix with suitable lubricants.
