Phillips 66 Bentone NLGI Grade 2
Categories: Fluid; Lubricant; Clay Gellant

Material Notes: 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 particularly 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 extreme-pressure and antiwear additives to provide outstanding protection for bearings and moving parts exposed to heavy loads and high operating temperatures. It retains its consistency at high temperatures and has good water washout resistance and good storage stability.

Applications:

  • Banbury mixers
  • Drying ovens
  • Jaw crushers
  • Kiln cars
  • Rolling and strip mills
  • Steel mills
  • Aluminum, cement, glass and rubber plants
Features/Benefits:
  • Non-melt clay thickener
  • Excellent resistance to changes in consistency at high temperatures
  • Good extreme-pressure and antiwear properties
  • Adheres to metallic surfaces
  • Good shear stability
  • High film strength
  • Resists water washout
  • Good mechanical and storage stability
