General Description:
NNL690G has been developed to greatly enhance the lubricating properties of extreme pressure gear oils.Changing industry technology dictates improvements and demands specialization.Power Up has met this challenge head on.
Applications:
Recommended wherever EP (extreme pressure) oils are used at 5% rates.Including but not limited to:
Gear reducers.
Bearing housings.
Chain drives.
Standard transmissions (except synchromesh at 3% rates)
Bull gears and pinions
Mud pumps
Differentials (except limited slip or posi-trac)
Final drives.
Cone and jaw crushers
Rotary tables.
Tube and ball mills
Drop boxes
General Description:
NNL 690G is specially formulated for use in all types of mobile and industrial equipment where Extreme Pressure (EP) oils are called for (API GL-3 or greater). Specific applications include gear reducers, bearing housings, differentials (except posi-trac or limited slip), cone and jaw crushers, pulverizing equipment, final drives, conveyer drive gear boxes, standard transmissions, drop boxes, rotary tables, tube and ball mills, chain drives, mud pumps, bull gear and pinion sets, etc.
Primary Benefit of NNL 690G:
The primary benefit of NNL 690G is to reduce the friction caused by asperity (metal to metal) contact in the boundary lubrication regime. It is designed for lubricated systems which call for extreme pressure (EP) oils and engines requiring low ash-content oils.
Secondary Benefits of NNL 690G:
Reduces ultrasonic wear noises which relates directly to component wear.
Reduces dry start-ups.
Lowers operating temperatures and slows oil degradation.
Decreases wear in cold temperature applications (conventional EP additives are very dependent upon temperature to chemically react with the wear surfaces). The high film strength protection provided by NNL 690G is less dependent on temperature.
Reduces fuel and/or electrical power consumption in many applications.
Improves filtration efficiency by reducing the generation of large wear particles.
Increases equipment availability and extends equipment life.
Product Application and Availability: NNL 690G is intended for use in all types of mobile and industrial equipment where EP oils are called for. NNL 690G should be applied with each oil change at 5% of the gearbox capacity. With gear oils heavier than ISO 320, NNL 690G should be used at 3%. In internal combustion engine crankcases using low ash or ashless oils, NNL 690G should be used at 3% of the oil volume with each oil change. It is also suitable for use in automatic transmissions at an application rate of 1%, in power shift transmissions at 3%, and in circulating systems at 3% or 5%, depending on the severity of the service. NNL 690G is compatible with mineral based oils and with synthetic oils based on polyalphaolefins and diesters. At recommended applications rates, it will not affect typical gear or engine oil viscosity ratings or seal materials. NNL 690G is available in 1L bottles, 5L and 10L jugs, 20L pails and 205L drums. |  |

Special Notations
Viscosity:
A 5% application of NNL 690G in typical 90 weight gear oil results in little or no change in viscosity or viscosity index of the oil.
Pour Point:
NNL 690G is formulated to have a negligible effect on the pour point of typical engine oils.
Ash Content:
Power Up NNL 690G has a very low ash content (less than 0.2%). It is therefore suitable for use in the crankcase of engines that require a low ash or ashless oil.
Application:
NNL 690G is intended for use in gearboxes using extreme pressure (API GL-3 or greater) oils. In engine crankcases, NNL 690G should be added at 3% of the oil volume each time the oil is changed. It can also be used in automatic transmissions at an application rate of 1%, power shift transmissions at 3% and in circulating systems at 3% to 5%, depending upon operation conditions. NNL 690G is compatible with all mineral oils and polyalphaolefin and diester based synthetic oils. NNL 690G is not recommended for use with water based fluids, phosphate esters or polyglycol fluids.
