Mobil SHC Gear 22M (16 Gal. Keg)
Specially formulated for use in heavily loaded, low-speed gears, Mobilgear SHC 22M is an ultra-high-viscosity synthetic lubricant designed for low-speed open gearing that drives stationary rotating machinery. Specific applications include kilns and mills in metal mining, cement and limestone production, and sugar plants. Product application is by spray nozzle systems. Composed of synthetic base stocks, Mobilgear SHC 22M has remarkable low-temperature fluidity, even at high viscosity grades, which can be pumped over relatively long distances. These products offer excellent thermal/oxidative properties, which perform at high levels even in severe high and low temperature operating conditions and with very slow-moving gears. Mobilgear SCH 22M ensures exceptional rust and corrosion inhibition, plus safeguarding against wear. Reduction of hard-packed gear root deposits and increased pumpability with Mobilgear SHC 22M means prolonged gear life and lower maintenance costs.
Features
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.
