Mobilgear SHC Series

Gear Oils

Product Description

The Mobilgear SHC Series lubricants are supreme performance heavy-duty gear oils primarily designed for all kinds of enclosed

gearing as well as plain ａnd rolling element bearings. They are formulated from wax-free polyalphaolefin (PAO) synthetic base stocks

that have exceptional oxidation ａnd thermal properties ａnd excellent low temperature fluidity. The combination of a naturally high

viscosity index ａnd a unique additive system enables these products to provide outstanding performance under severe high ａnd low

temperature operating conditions. The wax-free nature of the PAO base oils also contributes to the products’ excellent low temperature

performance. They have outstanding EP properties ａnd resistance to shock loading. The base stocks have inherently low traction

properties that result in low fluid friction in the load zone of non-conforming surfaces such as gears ａnd rolling element bearings.

Reduced fluid friction produces lower operating temperatures ａnd improved gear efficiency.

The Mobilgear SHC Series covers a very wide viscosity range, from ISO VG 150 to 6800. Accordingly, they find application in a wide

range of enclosed gear applications, as well as plain ａnd rolling element bearings. Because of the very high viscosities available, this

family can meet the lubrication needs of very slow speed ａnd high load/high temperature gears ａnd bearings; they are ideal for

situations in which conventional products operate in the boundary regime. They may be substituted for all-loss lubricants in certain open

gear applications, but cost of equipment modifications needs to be balanced against the benefits of recirculating the lubricant.

Mobilgear SHC Series lubricants are the products of choice for many OEMs ａnd customers world-wide based on their wide application

range ａnd superb performance in tough situations.

Features & Benefits

The Mobilgear SHC family of lubricants is a leading member of the SHC brand of products that are world-renowned for their innovation

and performance. These products are based on synthesised PAO base oils pioneered by our scientists ａnd which are now the leading

non-mineral base oil used in finished lubricants. These molecular design base stocks provide many benefits not possible with mineral

stocks, ａnd they result in final products with unique performance features ａnd customer benefits.

Our formulation scientists have used a proprietary additive combination that fortifies the PAO base oils to provide excellent EP ａnd antiwear

performance, even in shock load situations. The resulting finished products have shown exceptional performance in OEM

evaluations, customer field tests ａnd commercial use. The higher viscosity grades are particularly effective in low-speed, high load, high

temperature situations ａnd provide excellent gear & bearing protection, longer oil life ａnd excellent all-round service compared with

conventional products.

Features Advantages ａnd Potential Benefits

Outstanding load-carrying ａnd antiwear properties Extended gear life ａnd reduced maintenance costs

Very high viscosity grades available, without reduction of

properties or performance capability

Provides excellent EHL film protection of gears ａnd bearings even

at slow speeds, high loads ａnd high temperatures

Can be used to convert all-loss systems to circulation

Can replace grease in some applications resulting in plant product

consolidation

High viscosity index ａnd wax-free base oils Trouble-free operation over a wide temperature range particularly

at extremely low temperatures.

Low traction properties Improved gear efficiency ａnd lower operating temperatures lead

to lower operating costs

Outstanding thermal/oxidation resistance ａnd long product life Reduced lubricant consumption, reduced product ａnd change-out

costs

Light colour Minimises need for gear cleaning prior to inspections, reducing

maintenance costs

Applications

Application Considerations: While the Mobilgear SHC Series are compatible with mineral oil based products, admixture may detract

from their performance. Consequently it is recommended that before changing a system to one of the Mobilgear SHC Series, it should

be thoroughly cleaned out ａnd flushed to achieve the maximum performance benefits.

Mobilgear SHC Series oils are recommended for all types of enclosed steel-on-steel gear drives. They are suitable for both circulation

and splash lubrication systems. The range of viscosity choices in the Mobilgear SHC Series from ISO 150 to ISO 6800, provides the

right lubrication option for low temperature applications where pour points of -46ºC are required to high temperature applications where

operating temperatures of 121ºC are encountered. They are particularly recommended for gear sets operating under heavy or shock

loads ａnd low speeds where boundary lubrication may prevail. For clarity, applications for this product family are described for two

viscosity ranges, as follows:

Mobilgear SHC 150 to 1500 - Industrial enclosed spur, helical ａnd bevel gear drives, especially heavy-duty applications especially

those found in mining, chemical processing, metals ａnd paper sectors.

Mobilgear SHC 150 to 1500 - Industrial gearing for conveyers, agitators, dryers, extruders, fans, mixers, presses, pulpers, pumps

(including oil well pumps), screens, extruders ａnd other heavy duty applications

Mobilgear SHC 150 to 1500 - Marine gearing including main propulsion, centrifuges, deck machinery such as winches, windlasses,

cranes, turning gears, pumps, elevators ａnd rudder carriers

Mobilgear SHC 3200 ａnd 6800 - Industrial enclosed spur, helical ａnd bevel gears, especially slow speed, and/or high load units

Mobilgear SHC 3200 ａnd 6800 - Plain ａnd rolling element bearings, especially in slow speed, and/or high load applications

Mobilgear SHC 3200 ａnd 6800 - Railroad DC Traction Motor drives

Mobilgear SHC 3200 ａnd 6800 - Certain open gear applications such as oiling pinions or specially designed circulation systems
