66 Proven Performance - Food Mobil SHC Polyrex 462 provides $23,000 annual cost savings in a sugar beet processing plant Benefit NSF H-1 registered Mobil SHC Polyrex 462 grease enables a sugar beet processing plant to save annually $23,000 in spare part and maintenance costs. Situation The product used to lubricate the critical components of a steam dryer at continuously high temperatures of 150 C (302 F) in a humid environment was leading to excessive wear on sluice jaws and lubricating rings due to uncontrolled oil bleeding. Grease stiffening was causing a malfunction of magnetic valves of the centralized grease system. Impact Mobil SHC Polyrex 462 was used during an intense sugar campaign period. Inspection of the critical components showed no evidence of wear. The grease maintained its consistency resulting in flawless operation of the centralized grease system. Mobil SHC Polyrex 462 was the only NSF-H1 registered grease which performed under these severe conditions. 9

67 Proven Performance - Paper Supercalender profile roll stack running at 360 rpm & 110 C (230 F). Competitive grease (ISO 1500 synthetic) not providing adequate lubrication. Oil separation observed during service. Bearing life experienced < 1 year. Mobil SHC Polyrex 462 tested, bearing inspection performed at 1 year. Grease inspection showed no detectable oxidation, bearings showed no signs of wear. 10

68 Proven Performance - Paper Paper machine dryer felt roll bearings only accessible for relubrication every six weeks. Temperatures > 93 C. Testing of Mobil SHC Polyrex 462 vs. Mobilith SHC PM & Shell Stamina HDS. Mobil SHC Polyrex 462 maintained consistency, less hardening over six week cycle vs. the other products. 11

69 Proven Performance - Plastic Film extrusion MDO section steam heated rolls. Bearing operating temperature 135 C (275 F). Speeds rpm define mixed boundary/ehl conditions at these temperatures. Mobil SHC Polyrex 462 follow-up inspections showed no oil separation, no hardening and no deposits Mobil SHC Polyrex 462 gave equivalent performance to a specialty niche high temperature product. 12

70 Proven Performance - Cement Exhaust fan shaft bearings, 2500 rpm & 100 C. Historical failure rate was every 4-6 months. Previous lithium complex grease showed hardening and oxidation after failure. Mobil SHC Polyrex 462 extended bearing life to 12 months, reaching a planned shutdown and maintenance. 13

71 Proven Performance - Cement Drive & head bearings experience high level of clinker dust contamination. Dust ingress caused higher bearing operating temperatures, increased vibration, leading to a 6 8 month bearing life. Mobilith SHC 460 did not improve bearing life, becoming stiff and unable to lubricate. Mobil SHC Polyrex 462 tested for 10 months before inspection. Operating temperatures and vibration signatures were normal. Grease consistency, although contaminated, showed no hardening. Bearing condition looked good. 14

72 Field Application Summary Mobil SHC Polyrex: high temperature lubrication recommended up to 170 C Mobil SHC Polyrex 462 was successfully field tested in the following applications: Supercalender 110 C Dryer felt roll bearings >93 C Exhaust blower 100 C (210 F) Clinker elevator Dust contamination Film extrusion, steam heated rolls 135 C Fluidized bed steam heated dryer 150 C These field tests have been documented and are available for use 15
