Mobilith SHC PM 460 (110 lb. Keg)

Mobil 105789

Mobilith SHC PM 460 is a supreme performance NLGI Grade 1.5 heavy duty grease. It is formulated with Synthetic ISO Viscosity Grade (VG) 460 base fluid and a high quality lithium complex thickener. It has a recommended operating temperature range of -30 °C to 150 °C with appropriate relubrication intervals. Mobilith SHC 460 meets or exceeds DIN 51825: (2004-06) KPHC 1-2N-40. This grease has a lower coefficient of friction than similar conventional greases and has the potential to provide increased mechanical life and reduced energy consumption. Mobilith SHC PM 460 is formulated without dye specifically for use in Paper Machines (PM) so as not to stain the paper.

Mobilith SHC PM 460 is an extreme pressure (EP) grease recommended for tough industrial and marine applications. As it is an NLGI Grade 1.5, it is suitable for both NLGI Grade 1 and 2 applications. It provides outstanding bearing protection under heavy loads at low-to-moderate speeds and in applications where water resistance is a critical factor. Mobilith SHC PM 460 has demonstrated outstanding performance in steel mills, paper mills and marine applications.

Product Data Sheet

The Mobil SHC brand of oils and greases is recognized and appreciated for their innovation and outstanding performance. The Mobilith SHC series symbolizes our continued commitment to using advanced technology to provide outstanding products. A key factor in the development of Mobilith SHC PM greases was the close contacts between our scientists and application specialists with key paper machine designers to ensure that our product offerings would provide exceptional performance in this continually evolving, and increasingly severe, equipment area.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobilith SHC PM greases. These benefits include excellent resistance to acidic and alkaline water, enhanced bearing protection and bearing life, wide temperature range of application, and longer grease life.

To combat high thermal exposure our product formulation scientists chose proprietary synthetic base oils for Mobilith SHC PM grease because of their exceptional thermal and oxidative resistance. Our scientists developed a high performance lithium complex thickener technology and used specific additives to enhance Mobilith SHC PM greases to meet the needs of modern and future paper machines. Mobilith SHC PM greases offer the following features and benefits:

Features Advantages and Potential Benefits
Outstanding high temperature and low temperature performance Wide application temperature range, from -40ºC to 150°C with excellent protection at high temperatures and low torque, easy start-up at low temperatures
Excellent protection against wear, rust and corrosion, including acidic water Reduced downtime and maintenance costs because of reduced wear, rust and corrosion even in acidic and alkaline water environments
Excellent structural stability and oxidation resistance Extended service life with longer intervals between relubrication and improved bearing life
Excellent wear protection under heavy loads, slow speeds, and high temperatures Outstanding protection of slow speed, heavily loaded bearings, with extended bearing life
Outstanding structural stability in the presence of water Retains excellent grease performance in hostile aqueous environments
Low volatility Helps resist viscosity increase at high temperatures to maximize relubrication intervals and bearing life

Application Considerations: While Mobilith SHC PM greases are compatible with most mineral oil based products, admixture may detract from their performance. Consequently it is recommended that before changing a system to one of the Mobilith SHC PM greases, it should be thoroughly cleaned out to achieve the maximum performance benefits. If dismantling the system for cleaning before changeover isn't feasible, then thorough purging and increased relubrication intervals are strongly recommended. Contact your local ExxonMobil Lube Engineer for consultation on this approach.

Mobilith SHC PM greases are recommended for critical rolling element bearing applications in paper machines. Included among these are:

  • Wet end paper machine bearings.
  • Highly loaded press section bearings.
  • High-temperature felt roll and calendar stack bearings.
