MOLYKOTE® 44 High Temp. Bearing Grease, Medium

Bearing failures in high-temperature environments almost always come down to one of two root causes: the grease melts and migrates out of the bearing, or the base oil oxidizes and leaves a hardened residue that accelerates wear. MOLYKOTE® 44 High Temperature Bearing Grease, Medium addresses both.

The phenyl-methyl silicone base oil has one of the lowest evaporation rates of any grease chemistry at elevated temperatures. It does not carbonize or form deposits when pushed near its upper service limit. The lithium thickener system provides mechanical stability under shear, which matters in applications where the bearing is seeing continuous rotation and moderate loads. The result is a grease that stays in the bearing, continues to lubricate, and does not require regreasing intervals compressed by thermal degradation.

MOLYKOTE® 44 High Temperature Bearing Grease, Medium is compatible with most common engineering plastics and elastomers, which makes it suitable for mixed-material assemblies common in conveyor systems, fan motor housings, and electrical switchgear. It also delivers reliable low-temperature startup performance down to -40C, making it a practical single-product solution for equipment cycling between ambient cold and high operating temperatures.
