Our Mobilith SHC™ PM Series synthetic greases are designed specifically for today’s most severe paper machine applications, including extreme temperatures, exposure to process water and low starting torque.
These synthetic greases provide outstanding protection against rust and corrosion from acid and alkali water chemistries, making them ideal for wet end paper machine bearings. They also can:
- Reduce downtime and maintenance costs
- Extend service life with longer intervals between relubrication
- Extend bearing life
Features and Benefits
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 |
Applications
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.
