KN-2783 Manual Four Ball Wear Tester

The four-ball wear-test method can be used to determine the relative wear-preventing properties of greases under the test conditions and if the test conditions are changed the relative ratings may be different. No correlation has been established between the four-ball wear test and field service. The test method cannot be used to differentiate between Extreme Pressure (EP) and Non-Extreme Pressure (Non-EP) GreasesRead more >

KN-6079 Diesel Lubricating High Frequency Reciprocating Testing Machine(HFRR)

Diesel fuel injection equipment has some reliance on lubricating properties of the diesel fuel. Shortened life of engine components, such as diesel fuel injection pumps and injectors, has sometimes been ascribed to lack of lubricity in a diesel fuelRead more >

KN-5001 Ball-on-Cylinder Lubricity Evaluator (BOCLE)

KN-5001 Ball-on-Cylinder Lubricity Evaluator (BOCLE) conforms to ASTM D5001 Standard Test Method for Measurement of Lubricity of Aviation Turbine Fuels by the Ball-on-Cylinder Lubricity Evaluator (BOCLE) and ASTM D6078 Standard Test Method for Evaluating Lubricity of Diesel Fuels by the Scuffing Load Ball-on-Cylinder Lubricity Evaluator (SLBOCLE).. The fluid under test is placed in a test reservoir in which atmospheric air is maintained at 10% relative humidity. A non-rotating steel ball is heldRead more >

KN-3427 Air Release Value Tester

Agitation of lubricating oil with air in equipment, such as bearings, couplings, gears, pumps, and oil return lines, may produce a dispersion of finely divided air bubbles in the oil. If the residence time in the reservoir is too short to allow the air bubbles to rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system. This may result in an inability to maintain oil pressure (particularly with centrifugal pumps), incomplete oil films in bearings and geRead more >

KN-1816 Insulating Oil Dielectric Breakdown Tester

The dielectric breakdown voltage of an insulating liquid is of importance as a measure of the liquid ability to withstand electric stress without failure.Read more >

KN-392 Grease Separation Apparatus

KN-392 Grease Separation Apparatus conforms to the GB/T392, The apparatus covers the determination of the tendency of a lubricating grease to separate oil during storage in both normally filled and partially filled containersRead more >

KN-6184 Oil Separation Apparatus for Grease

When a lubricating grease separates oil, the residual material changes in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are intended to correlate with oil separation that occurs in 35-lb pails of grease during storage. They are not intended to predict oil separation tendencies of grease under dynamic service conditionsRead more >

KN-1742 Oil Separation of Lubricating Grease

When a lubricating grease separates oil, the remaining composition increases in consistency. This can affect the ability of the product to function as designedRead more >

KN-121 Apparatus for Oil Separation from Lubricating Grease

KN-121 Apparatus for Oil Separation from Lubricating Grease conforms to IP 121 Determination of Oil Separation from Lubricating Grease – Pressure Filtration Method. A cylindrical column of grease resting on a metal gauze cone is subjected to a fixed pressure in excess of the hydrostatic pressure of the grease. The quantity of oil separated through the gauze after standing for 42h or 168h at 40℃ is taken as a measure of the stability of the grease towards oil separation during storage.Read more >
