Mobil SHC Gear 22M ａnd 46M
Mobil Industrial, China
Gear Oils
Product Description
Mobil SHC Gear 22M ａnd 46M are supreme performance ultra high viscosity synthetic lubricants designed specifically for use in heavily loaded, low speed open gears where boundary lubrication conditions often prevail. They are formulated from synthetic base stocks, which have remarkable low-temperature fluidity, even at such high viscosity grades. These ultra high viscosity products can be pumped over relatively long distances ａnd use standard spray application equipment. The combination of a naturally high viscosity index ａnd a unique additive system gives the products exceptional thermal/oxidative properties ａnd provides outstanding performance under severe high ａnd low temperature operating conditions even with very slow moving gears. The additive formulation also provides excellent gear scuffing protection, anti-wear performance ａnd rust ａnd corrosion inhibition.
Mobil SHC Gear 22M ａnd 46M exceed Falk Corporation＇s minimum viscosity requirements for intermittent lubrication of gears - winter ａnd summer grades, respectively. These grades also meet the viscosity requirements for AGMA lubricant numbers 14R ａnd 15R, respectively, although they are not residual lubricants, but are leading edge synthetic products. Mobil SHC Gear 22M ａnd 46M do not contain any solvent or any asphaltic-type base oil.
Features ａnd Benefits
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 |
Applications
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
