Mobil SHC Gear 22M and 46M lubricants are leading members of the Mobil SHC brand of products that are world-renowned for their innovation and performance. These scientifically engineered synthetic lubricants symbolize the continuing commitment to using advanced technology to provide outstanding lubricant products. Mobil SHC Gear 22M and 46M provide benefits not possible with mineral stocks, particularly under extreme high and low temperature operating conditions, and deliver performance features and customer benefits.

Our formulation scientists have used innovative combinations of base oils plus a proprietary additive combination that fortifies the base oils to provide excellent gear scuffing protection and anti-wear performance, even in shock load situations. The resulting finished products have shown exceptional performance in OEM evaluations, customer field tests and commercial use. These ultra high viscosity products are particularly effective in low-speed, high load, high temperature situations and provide excellent gear and bearing protection, longer oil life and excellent all-round service compared with conventional products.

Specific features and potential benefits for the Mobil SHC Gear 22M and 46M lubricants include:

Features Advantages and Potential Benefits
Thick EHL fluid film formation and selected additives provide outstanding load-carrying, antiwear and tackiness properties Helps extend gear life, less downtime and reduce maintenance and replacement cost
Avoids potential for solvent retention and reduced viscosity with solvent-type products
Provides much thicker EHL film compared with semi-fluid grease products
Excellent pumpability at ambient temperatures Helps reduce in pump replacement costs
Uses existing lubricant spray equipment Low-cost conversion from asphaltic of semi-fluid grease products
Lower application rates than greases, less waste compared with asphalt/solvent products Helps reduce lubricant consumption and disposal costs
Does not contain solids or asphaltic resins Absence of hard-packed gear root deposits results in reduction in downtime and maintenance costs
Light colored product Helps avoid need for costly gear cleaning prior to inspection
Solvent-free Helps avoid potential safety issues related to volatile, low flash solvent


Application Considerations: Normally, conversion to Mobil SHC Gear 22M or 46M from asphaltic or grease products will be a simple process with no change in lubricant spray equipment. It is recommended that the gears be thoroughly cleaned to take advantage of the light color of these synthetic products. Consult your Mobil representative for further details on lubricant conversion.

Mobil SHC Gear 22M and 46M are designed specifically for use in heavily loaded, low speed open gearing which drive stationary rotating machinery. Product is typically applied by intermittent by spray nozzle systems. Specific applications include:

  • Kilns and mills in metal mining, cement and limestone production and in sugar plants
  • Slow speed, heavily loaded plain and rolling contact bearings
