Mobil SHC Gear 46M (16 Gal. Keg)
Mobil SHC Gear 46M is a supreme performance ultra-high viscosity synthetic lubricant engineered for use in heavily loaded, low-speed open gearing that drives stationary rotating machines such as in kilns and mills in metal mining, cement and limestone production, and in sugar plants. Formulated from synthetic base stocks with exceptional low-temperature fluidity, Mobil SHC Gear 46M can be pumped over relatively long distances and uses standard spray application equipment. The thick EHL fluid film formation and selected additives in this lubricant provide remarkable load-carrying, anti-wear and tackiness properties, which prolong gear life, resulting in less downtime, plus reduced maintenance and replacement costs. The superior pumpability of Mobil SHC Gear 46M helps lower pump replacement costs and reduces waste. Using Mobil SHC Gear 46M oil ensures superior lubrication and protection of gearing, plain and rolling contact bearings.
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.
