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.
