“Our plant had excessive oil leakage and suspected oil evaporation on our paper machine drying cylinders, which work at speeds of 360 revolutions per minute with a temperature range from 110 to 125 degrees C and a centralized oil lubrication system. Operations personnel has faced this problem since the installation of 12 extra drying cylinders that use the same oil with the same viscosity (ISO VG 150). The sump temperature is about 72 degrees C. Before installation, evaporation was less, and there was no leaking. I believe they need to change to a higher viscosity or a synthetic alternative, but how do you choose the right lubricant in such a case?”
