Description

OKS 4240 is a special grease for the lubrication of ejector pins in the plastics industry. Areas of application Lubrication of ejector pins in the plastics industry at high temperatures and slow movements Lubrication of rolling and friction bearings at extremely high temperatures and aggressive operating conditions Advantages and benefits Extraordinarily good resistance to vapours occurring during plastic processing Good plastic and elastomer compatibility Excellent temperature resistance Lowest evaporation losses, also at high temperatures ensure long regreasing intervals Good media resistance Also suitable for fast-runing bearings thanks to low share of solid lubricants Technical specifications Operating temperature: -20 °C → +300 °C NLGI grade: 2 DN factor (dm x n): 350,000 mm/min Base oil viscosity (40 °C): 440 mm²/s Four-ball test rig (welding load): 4,800 N Applications Clean the lubricating points well for optimal effect. Subsequently blow out with dry compressed air. Before greasing for first time, remove anti-corrosion agent. Apply grease evenly to functional surfaces. Fill bearings running slowly completely, fill high-speed bearings (DN value > 100,000) only up to about 2/3 of the free space inside the bearing. The bearing and machine manufacturer's instructions should be observed. Relubrication at temperatures under 200°C not required. Assess the lubrication frequency and quantity on basis of service conditions. Only mix with suitable lubricants.
