After seeing so much advertising over the years for this lubricant, we were extremely surprised by the results and are sure you will be, too.

4 Dec 2009 A test rig with dead weights was used for bearing loading in tests on journal bearings lubricated with water by Andersson and Lintula (1994) and  20 Oct 2019 Friction and temperature testing can help understand the effect of various of cooling and the oil flow rate and hence of the oil temperature. Title: Study of a bearing test bench capable to simulate wear in diesel work, show the difficulties of developing new test methods, such as problems in the oil   9 Jun 2015 Oil level on bottom ball of the bearing (Graphics courtesy of the author). Because water in the oil is invisible at low levels, a lab should test the  Lubricant testing and oil condition monitoring provides quality and condition assessment of lubricants and oils used in engines and other expensive machinery  The higher the number, the more thermally stable the oil is over a wide range of temperature. This means that as the oil warms up, it loses less viscosity. This bearing and oil test demanded the engine be subjected to multiple tear-downs to replace all the bearings but the results were well worth the effort. I’ve come across a couple of engine oil / oil additives companies that use the timken bearing test – also sometimes known as the “one arm bandit” test or bearing lubricity test – to display the efficacy of their oil or oil additive.

Main bearing sleeves come in two half-moon sections, one that sits inside the main bearing cap and one that sits in the engine block. The crankshaft journal spins within the two. The main bearings have oil holes that lubricate the journal. Main bearings can wear with normal age,

Timken OK Load is a standardized measurement that indicates the possible performance of extreme pressure (EP) additives in a lubricating grease or oil. The units of measurement are pounds-force or kilograms-force. This measurement is performed using a special test machine and standard The test machine consists of a standardized bearing race mounted on a

3 Nov 2017 Verification test included bearing friction measurements, defining operational values and effect of oil pressure, oil temperature.

"The 4-ball test (ASTM D4172) is often used as a screening test for many different lubricant types that contain antiwear additives or similar base oil properties. Other tribo-mechanical bench tests are often used as well, including the Timken Test (ASTM D2782) and the Pin and V-Block (ASTM D2670). AMSOIL SABER ® Professional Synthetic 2-Stroke Oil mixed at 100:1 resisted deposits better than RedMax* 2-Stroke Engine Oil mixed at 50:1.

TestOil’s engine oil analysis is designed to uncover lubrication anomalies generated by faulty mechanical issues as well as mechanical issues brought on by lubrication problem. It tracks fuel dilution (%), base number, viscosity @100C and coolant contamination. This report is ideal for fleet engine owners.
