Roller bearing lubricant grease

Our Mobil Centaur XHP™ 460 Series multipurpose greases are designed to provide rust protection in water-saturated environments. With a balanced combination of water washout and water spray-off resistance, as well as excellent corrosion protection, these calcium sulfonate greases are particularly well-suited for the demanding requirements of steel mill and paper machine equipment.

Mobil Centaur XHP 460 Series multipurpose greases provide:

  • Extreme-pressure protection for equipment with high/shock loads
  • High temperature oil bleed control
  • High water washout resistance and water absorption
