Once the cage starts to lose its integrity friction increases even more leading to total disintegration of the cage. This results in the two steel races and ball bearings remain pretty much intact (although damaged), however the cage disintegrates into pieces. Because the balls are no longer properly spaced within the inner and outer races, the two races separate leading to catastrophic failure of the bearing. In IMS failures the debris is carried throughout the engine causing even more damage.

Bearing knowledge

Notice the apparent condition of the ball

This type of cage failure is generally created from vibration that is associated with the overall bearing failure. This means its collateral damage.

FYI- The "plain bearing" is the same OD as the "plain bearing" on the opposite end of the IMS which never wears and seldom has a scratch on it even after a full blown, massive, engine failure.

Larger diameters of plain bearing didn't function as well in my direct development, due to surface speeds related to the larger diameter components. The IMS Solution wasn't developed overnight, in fact it is the very first M96 engine related product that I invented, it pre-dates everything; but took the longest to perfect, hence the reason why it was divulged in 2012. You name it, and we tried it with the IMS Solution.

Originally developed only for my own line of engines, I honestly never cared if the IMS Solution ever made it into another engine outside of my complex.

The plain bearing on the opposite end of the IMS would be lucky to see 10% of the ball bearing loads so there is no point in this comparison. Surface speeds of plain bearings are an issue with Aluminium a nickel bronze would be a better choice.

Nickel Bronze as well as other types of bronze materials proved unsuccessful in direct comparisons as materials for the IMS Solution.

Various diameters were also directly compared and nothing worked as well as the diameter that we chose. The load carrying capacity of a journal bearing isn't solely defined by diameter.



It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.

This is what I would like to see available to buy. It adds some of the features found in the later model larger bearing, including a press fit of the bolt to the bearing inner race, and a larger bolt altogether. Basically it is a redesigned bolt and a slightly machined flange seal.



I have found that the inner race of the bearing gets considerably hotter than the outer race. I think that may be why Porsche made the bolt a full-length press fit on the inner race on the larger bearing.

With the head of the bolt being much more massive, it can help dissipate heat from the bearing, or it can be machined for other purposes, like adding a safety bearing.

Being able to add a washer between the bolt head and bearing, perhaps stainless steel, could help prevent push-on separators from popping off.

Making the shank of the bolt as long as possible could help dissipate heat, or a larger heat sink could be bolted on, or a cantilever brace could be installed, or the end of the bolt could be drilled to accept a temperature sensor, like a thermocouple.

Managed to graph a proper oil seal to a 6402 bearing.



So far pleased with the integrity and sealing.
It requires a spacer to fit into the seal.
