Mobilith SHC PM 460
Mobilith SHC PM 460 is part of the Mobilith SHC PM Series, a range of superior performance greases specifically developed for demanding paper machine applications. These greases are formulated using synthetic base oils combined with advanced lithium complex thickener technology to deliver exceptional lubrication performance in environments exposed to high temperatures, heavy loads and water contamination. The synthetic, wax-free base fluid provides excellent low-temperature pumpability while maintaining strong film strength at elevated temperatures.
One of the key advantages of Mobilith SHC PM 460 is its outstanding resistance to water contamination, including acidic and alkaline process water commonly found in paper mills. This helps maintain effective lubrication and protects bearings from corrosion, even in harsh wet-end conditions where conventional greases may fail.
Mobilith SHC PM 460 also provides excellent wear protection under heavy loads and slow-to-moderate speeds. The higher viscosity base oil (ISO VG 460) provides a thicker lubricating film compared to lower viscosity grades, making it particularly suitable for more heavily loaded applications. This helps reduce wear, extend bearing life and improve overall equipment reliability.
Another important benefit is its excellent thermal and oxidation stability. The synthetic base oils resist degradation at high temperatures, allowing for extended grease life and longer relubrication intervals. This supports reliable operation in high-temperature dry-end sections of paper machines where lubrication demands are severe.
Mobilith SHC PM 460 is recommended for critical rolling element bearing applications in paper machines, including wet-end bearings, press section bearings and high-temperature felt roll and calendar stack bearings. It is particularly well suited for heavily loaded bearings where enhanced film strength and durability are required.
Physical characteristics include NLGI 1.5 consistency with lithium complex thickener and off-white appearance. Mobilith SHC PM 460 has base oil viscosity of approximately 460 mm²/s at 40°C and a dropping point of approximately 275°C. The grease delivers excellent water resistance, high load-carrying capability and reliable long-term protection in severe industrial environments.
