Loads represent the cylinder-loads of the Block-on-Ring test apparatus, not loads experienced by a real bicycle chain, bearing or engine.
“>” means seizure was not observed up to the highest load applied in that test.
A lubricant may resist seizure yet still leave significant wear.
That's why we also measure the grooves formed on the metal surfaces.
02 / WHY IT MATTERS
Because Protection Is About More Than a Quiet Machine.
Whenever moving metal surfaces are insufficiently separated by lubricant, friction and wear can increase.
It matters inside bicycle chains, motorcycle chains, bearings and engines.
Resistance to Seizure
How well does a lubricant prevent mechanisms from seizure, as load increases, changes, or has impact characteristics?
Resistance to Wear
How well does a lubricant protect from damage, and maintains its lubrication properties under sustained mechanical load?
We examine both, so you can look beyond the headline numbers.

Bicycle Chain Lubricants
A bicycle chain relies on lubricant retained between its moving parts, which tends to be squeezed out and has limited self-regeneration capabilities. We compared Revolubes with six alternative chain-lubrication technologies to see how they cope with the conditions.
>282.19 kg
No seizure at maximum applied cylinder load.
Beyond Load: How Much Contact Pressure?
A smaller wear groove means the load is spread over a smaller contact area.
Compare the load, groove size and estimated average pressure together.

04 / UNDERSTANDING THE NUMBERS
It's Not Just About the Load.
Two lubricants may withstand the same load, yet leave very different wear grooves.
As the rotating ring wears a groove into the block, the contact area can increase. This spreads the applied load over a wider surface. A large load reading therefore tells only part of the story.
Seizure Resistance
The maximum load reached without seizure, or the load at which seizure occurs.
Surface Protection
The size and depth of the wear groove created under the conditions of the test.
Advanced: How is estimated contact pressure calculated?
Estimated average contact pressure [MPa] = Cylinder load [kg] × g [9.81 m/s^2] ÷ Groove contact area [mm²]
Here the recorded cylinder load already accounts for the testing machine's lever ratio: Scale load × lever ratio = Cylinder load.
This is a nominal average contact pressure calculated from the measured groove contact area. It is not a direct measurement of peak local stress or a certified ASTM seizure-pressure rating.
05 / HOW WE TEST
What Happens Inside the Test Machine?
AM Diagnostics uses a TIMKEN-style Block-on-Ring rig. A stationary metal block is pressed against a rotating ring. The lubricant sits at the contact, where load, movement and wear can be observed.
01 · Seizure Point Test
The applied load increases progressively until the mechanism seizes and the drive motor stops, or the maximum load for that run is reached.
The load and resulting groove measurements are recorded.
02 · Creep Test
A constant load is maintained for a defined period. Groove depth and geometry are measured after the test.
Motor current may be monitored as an indirect indicator of mechanical resistance; no quantified friction coefficient is claimed here.
These are AM Diagnostics in-house test procedures, not certified ASTM test methods.
05 / THE REFERENCE TEST
What Happens With No Lubricant?
In the unlubricated reference test, the mechanism seized at a cylinder load of 45.96 kg. The same reference conditions apply across the four tested product categories.

07 / QUESTIONS & ANSWERS
Frequently Asked Questions
Are these independent laboratory tests?
The tests were carried out by AM Diagnostics Ltd., the company behind Revolubes. They are internal comparative tests, not independent third-party certification.
Are these ASTM Timken results?
No. AM Diagnostics uses in-house Seizure Point and Creep Test procedures on TIMKEN-style Block-on-Ring equipment.
What does “>348 kg” mean?
The test reached that cylinder load without seizure. It does not mean seizure occurred at precisely 348 kg.
Does a higher seizure load always mean less wear?
No. Groove depth and contact area are also important, which is why the test interpretation considers both load and wear geometry.
What does estimated contact pressure mean?
It is the applied force divided by the calculated groove contact area. It describes nominal average pressure, not the complete local stress distribution.
Why are some Creep Test cells blank?
Only samples with groove depth below 0.25 mm progressed to the next stage. A dash means no result was recorded for that stage.
Does the engine-oil result apply to every engine oil?
No. The reported values describe the particular oil and 5% PM Tribo-Shield mixture tested under defined laboratory conditions.
Can the results predict real-world lifespan or power savings?
Not directly. Laboratory loading tests cannot be converted into real-world mileage, engine longevity or measured drivetrain power savings without separate validation.
Testing disclosure: AM Diagnostics Ltd., UK, is the company behind Revolubes. These are in-house comparative Block-on-Ring tests, not independent verification or ASTM certification. Cylinder loads are test-machine values, not allowable operating loads in actual equipment. Comparisons apply only to the tested samples and conditions.
