KML Agricultural Bearings are lubricated with Chevron SRI#2 from the factory. Chevron SRI#2 is a high temperature ball and roller bearing grease. It is formulated using a synthetic polyurea ashless organic thickener with additional rust and oxidation inhibitors. This grease provides superior corrosion protection in severe applications in incidental contact with both salt and fresh water. The temperature range of the Chevron SRI#2 is -20°F to 350°F (-29°C to 177°C). KML Agricultural Bearing units normal grease content is about one third to one half of the internal space inside the bearing. The grease used for replenishment should checked for compatibility before application.
