Mobilith SHC™ PM Series
Grease
Product Description
Mobilith SHC™ PM greases are superior performance products designed specifically for severe paper machine applications, including extreme temperature environments and exposure to different qualities of water. Mobilith SHC PM greases combine the unique features of a synthetic base fluid with those of a high quality lithium complex thickener. The wax-free nature of the synthetic base fluid provides excellent low temperature pumpability and low starting and running torque compared to other non-synthetic oil products of the same viscosity. The high viscosity index of the synthetic base fluid ensures excellent film protection at high temperatures. The lithium complex thickener contributes excellent adhesion, structural stability and resistance to water. These properties are complemented by a special additive system to provide rust and corrosion resistance, wear protection, thermal/oxidative resistance and to enhance water resistance properties. Mobilith SHC PM 220 and Mobilith SHC PM 460 are both NLGI grade 1.5 with base fluids of ISO VG 220 and 460, respectively.
Mobilith SHC PM greases are designed for use in the most critical rolling element bearing applications in paper machines. They provide outstanding protection against rust and typical acid and alkali water corrosion, making them ideal for the wet end of the paper machine. The low volatility and excellent oxidation stability of the PAO base stock ensures excellent service at high temperatures typical of dry end conditions.
The Mobilith SHC PM series has become the technology of choice for many paper mill operators, worldwide. Its reputation is based on exceptional quality, reliability and the proven performance benefits they deliver.
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:

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.
