Phillips 66 M220 Bearing Oil
Categories: Fluid; Lubricant

Material Notes: Bearing Oil M is a high-quality, rust and oxidation (R&O)-inhibited circulating oil specifically developed for the lubrication of backup roll bearings manufactured by Morgan Construction Company. It meets the performance requirements for “super demulsibility” as defined by Morgan’s Advanced Lubricant Specification, Revision 2.4, for use in hot and cold rolling mill operations. Bearing Oil M is formulated to provide rapid water separation, excellent oxidation resistance, protection against rust and corrosion, and resistance to foaming. It has excellent water-separating properties to minimize the formation of emulsions in circulating systems subject to contamination with large quantities of water, rolling solutions, dirt and scale. It has excellent oxidation resistance and thermal stability at high temperatures to minimize sludge and varnish formation, and provide long service life. It protects system components against rust and corrosion, and is resistant to excessive foam buildup that can interfere with proper lubrication.

Applications:

  • Backup roll bearings manufactured by Morgan Construction Company
  • Backup roll bearings in hot and cold rolling mills
  • Bearing lubrication in steel mills
  • Circulating systems where water contamination is a problem
  • Large, slow-speed gears in mixers and mills
Bearing Oil M meets the requirements of the following industry and OEM specifications:
  • Morgan Construction Advanced Lubricant Specification, Revision 2.4
  • U.S. Steel 135, Mill Circulating Oil
Features/Benefits:
  • Excellent water- separating properties
  • Excellent oxidation resistance and thermal stability
  • Protects against rust and corrosion
  • Good foam resistance
