Mobil Mobilith SHC PM 220 EP grease NLGI 1.5 for paper machines 16kg

Mobil Mobilith SHC PM 220 is a special Extreme Pressure (EP) grease KP HC 1-2 N -40 designed for severe paper machine applications, including extreme temperature environments and exposure to different qualities of water.

Mobilith SHC PM 220 is an 1.5 NLGI Grade beige grease with a synthetic PAO base fluid (ISO VG 220). Its operating temperature range is between -40º C* and +150º C.

• Volume: 16 kg bucket
• Also available in: 380 g cartridge, 174 kg barrel

Applications

• Mobilith SHC PM greases are recommended for critical rolling element bearing applications in paper machines, such as...
• Wet end paper machine bearings
• Highly loaded press section bearings
• High-temperature felt roll and calendar stack bearings

Specifications & Approvals

• DIN 51825:2004-06 - KP HC 1-2 N -40 

Features

• Wide application temperature range, from -40ºC to 150°C with excellent protection at high temperatures and low torque, easy start-up at low temperatures
• Reduced downtime and maintenance costs because of reduced wear, rust and corrosion even in acidic and alkaline water environments
• Extended service life with longer intervals between relubrication and improved bearing life
• Outstanding protection of slow speed, heavily loaded bearings, with extended bearing life
• Retains excellent grease performance in hostile aqueous environments
• Helps resist viscosity increase at high temperatures to maximize relubrication intervals and bearing life

Application Notes

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.

Product description Mobilith SHC™ PM

Exxon Mobil 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.
