Bentone Grease (new)

High Temperature Applications Extreme Pressure Clay Thickened Grease

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.

Bentone is manufactured with high quality, heavy, paraffinic base oils and a non-soap, bentonite clay thickener. It is fortified with EP and antiwear additives to provide outstanding protection for bearings and moving parts exposed to heavy loads and high operating temperatures. It retains good consistency at high temperatures, water washout resistance and storage stability.
