Mobil SHC PM 220
Mobil SHC PM 220 is a superior performance synthetic lubricant specifically developed for demanding industrial paper machine circulating systems. It is formulated to provide outstanding protection for gears and bearings operating under severe conditions. The advanced synthetic base fluids deliver excellent thermal and oxidation stability, while a balanced additive system enhances wear protection, corrosion resistance and long lubricant life. These characteristics help improve machine reliability and support increased production capacity.
One of the key advantages of Mobil SHC PM 220 is its excellent wide temperature performance. The lubricant features a naturally high viscosity index and low pour point, allowing reliable start-up at low temperatures while maintaining stable viscosity at elevated operating temperatures. This helps provide consistent lubrication performance in high-speed paper machines operating under severe conditions.
Mobil SHC PM 220 also delivers exceptional wear protection for gears and bearings. The shear-stable formulation maintains viscosity even when subjected to severe mechanical stress, helping reduce component wear and extend equipment life. Its low traction coefficient may contribute to reduced operating temperatures and improved energy efficiency.
Another important benefit is its excellent water separation and hydrolytic stability. Mobil SHC PM 220 readily separates water and resists emulsion formation, allowing easier water removal and maintaining lubrication performance in wet environments. The product also offers excellent filterability, helping keep oil lines clean and supporting efficient circulation and cooling performance.
Mobil SHC PM 220 is recommended for severe industrial paper machine circulating systems, including calendar roll lubrication and systems operating across wide temperature ranges. It is suitable for circulation systems lubricating gears and bearings and for applications requiring rapid start-up and reliable operation. The product is particularly effective in high output paper machines operating under demanding conditions.
Physical characteristics include ISO VG 220 viscosity grade with a kinematic viscosity of approximately 225 mm²/s at 40°C and 25.6 mm²/s at 100°C. Mobil SHC PM 220 has a viscosity index of approximately 127, a flash point of approximately 220°C and a pour point of approximately −36°C. The lubricant also provides excellent rust protection and strong hydrolytic stability, supporting reliable long-term performance in paper machine lubrication systems.
