Mobil SHC Polyrex 222 (16 Gal. Keg)
Designed to offer exceptional water resistance, high-temperature and balanced wear performance, Mobil SHC Polyrex 222 is a multipurpose Polyurea grease for use in both general and food and beverage industry applications. NLGI Grade 2 Mobil SHC Polyrex 222 is NSF H1 registered and complies with the FDA’s requirements for lubricants with incidental food contact. Mobil SHC Polyrex 222 is recommended for heavy-duty plain and anti-friction bearings, with an operating temperature range of -22 to 338 degrees F (-30 to 170 degrees C). Even at a wide range of temperatures, this grease resists oxidation and provides maximum machinery protection, allowing for extended re-lubrication intervals. This synthetic polymer-enhanced grease uses a carefully balanced combination of thickener, base oils and additives to safeguard your equipment from rust and corrosion, even in wet environments and applications where water washdowns are frequent.
Features
The Mobil brand of oils and greases is recognized around the world for its innovation and outstanding performance. Mobil SHC Polyrex utilizes the advanced thickener technology of the Mobil Polyrex family of greases to deliver a high performance, problem solving product for some of industries' toughest lubrication problems. Mobil SHC Polyrex brings that performance to another level through the addition of a unique combination of synthetic oils, polymer enhancement and a balanced additive package that is geared to deliver solutions to tough lubrication problems.

Applications
Application Considerations: While Mobil SHC Polyrex Series greases are compatible with many Polyurea and lithium complex greases, admixture may detract from their performance. Consequently it is recommended that before changing a system to one of the Mobil SHC Polyrex greases, it should be thoroughly cleaned out to achieve the maximum performance benefits. While the Mobil SHC Polyrex greases share many performance benefits, their applications are best described in terms of each product grade:
-
Mobil SHC Polyrex 005 is an NLGI 00 grade grease specifically designed for use in central grease systems. The enhanced pumpability and low temperature mobility make it an ideal choice for grease systems subject to low ambient temperatures, such as those found in food processing freezers or in outdoor applications. Mobil SHC Polyrex 005 may also be used for the lubrication of enclosed gears where oil leakage may be a concern. The recommended operating temperature range for this product is –30 to 170º C.
-
Mobil SHC Polyrex 221 is a multi-purpose, NLGI 1 grade grease specifically designed for use in heavy-duty plain and anti friction bearings. Mobil SHC Polyrex 221 has a recommended operating temperature range of -30° C to 170° C.
-
Mobil SHC Polyrex 222 is a multi-purpose, NLGI 2 grease recommended for heavy-duty plain and anti friction bearings. Mobil SHC Polyrex 222 has a recommended operating temperature range of -30º C to 170º C.
-
Mobil SHC Polyrex 462 is an NLGI 2 Grade grease recommended for heavily loaded plain and anti-friction bearings. It is also recommended for bearings where extreme temperatures are a concern, such as steam heated rolls, exhaust fan bearings, felt roll bearings, and oven conveyor bearings. The recommended operating temperature range is -20º C to 170º C.
