Feb 01 2016The experiments were performed with squalane oil a commercially available low molecular weight branched alkane (2 6 10 15 19 and 23-hexamethyltetracosane) that has been characterized by Bair and co-workers Its viscosity at ambient pressure and pressure–viscosity coefficient were determined to be 15 mPa and 18 GPa −1 respectively at 40 C (see Table 1)

Wide operating temperature range Ball and rolling element bearings operating continuously at temperatures between -15C and + 150C Prolonged grease service life - Enhanced oxidation resistance prolongs grease life at higher temperatures allowing extended re-greasing intervals

It decreases rolling friction between the raceway and the rolling elements sliding friction between rolling element and cage and sliding friction of guide surface between the cage and the bearing ring OPERATING TEMPERATURE OF BEARING (C) dn ISO VISCOSITY GRADE OF LUBRICATING OIL (VG) MEDIUM LOAD HEAVY LOAD / SHOCK LOAD DC 550 Fluid
