Bentone (old)

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 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.

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

Applications

  • Banbury mixers
  • Drying ovens
  • Jaw crushers
  • Kiln cars
  • Rolling and strip mills
  • Steel mills
  • Aluminum, cement, glass and rubber plants
