OKS 4240 is a special grease for the lubrication of ejector pins in the plastics industry. 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 consistency: 2 NLGI grade (DIN ISO 2137) viscosity at (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. Industries No matter what industry you come from, we at OKS have the right solution for you.
