IMS replaced with roller bearing?

[jaykay]

Just interested in the technical here: how are these folks accommodating thrust loads?
Are they mimimal or resolved ont the other end? Are they reying on oil film for thrust? What is the flow loss from oil pump as a result? Are there thrust load start up wear concerns if the IM shaft drains out

Martin,
Let me help you with identifying the bearing you have in your photo. I suggest it is not the LN Single Row Pro. There are not enough balls and there is only a single row ball race.

So to clarify, whose bearing is this -perhaps just another hybrid single row 6204-1RS? Like this:

Unless we confirm exactly what product we are discussing ,this will be a pointless mess.
BTW congratulations on developing your plain bearing solution to the IMSB issue. Seriously- this is USA ,we like competition !

It's 100% Ln bearing. Has LN serial number on the bearing and the flange. Our customer has called LN, and they confirmed it's their product, but have offered no help with the issue. It's documented by our customer in this rennlist tread:LN Engineering Ceramic IMS Bearing Failure at 30k miles - Rennlist Discussion Forums
The bearing we removed today is the same exact bearing, and has the same markings on bearing and the flange. It's just starting to wear out a little bit, but it does appear more loose than it should be.
