Mobilith SHC™ PM 460

Mobilith SHC™ PM 460 grease is superior a performance product designed specifically for severe paper machine applications, including extreme temperature environments and exposure to different qualities of water.

Product Description

It combines 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 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 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.

Applications:

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
