PEM2

Product Description

Applied Lubrication Technology Inc. PEM2 is a polyurea thickened grease specifically designed for the lubrication of high-speed ball and roller bearings in electric motors, alternators, generators, starters and other long life applications.  PEM2 is free from extreme pressure additives as required by many manufacturers of electric motor bearings, but is inhibited against rust and oxidation.  PEM2 has an operating temperature range of -40°C to 163°C (-40°F to 325°F).

Some of the typical physical properties of PEM2 are listed below.
