Phillips 66® Bentone is a high-quality, extreme pressure (EP), clay thickened grease developed for the lubrication of industrial equipment operating under heavy loads and at high temperatures. It is recommended for medium to large, low speed bearings operating at very high temperatures where conventional soap based greases typically fail to provide satisfactory lubrication.
