Hello,

this might chart be also helpful. It shows the specs and abbreviations for SKF bearings. Sorry, i have it only in german language. But it may help and also it might show that there are more things to consider than width, height and rpm.

@ Gelbster: i think the main problem is that this specific SKF 6204 2RSLTN9 bearing wasn't designed for an application in an engine oil bath. It was designed for a dry environment as a electric motor bearing. Also it isn't very heat resistant. For example it is not allowed to be heated up over 80 degrees celsius (176 degree fahrenheit) when you install it. No problem when you install it as an ISMB, because you have to cool it down, but it shows that it is not very heat resistant. In an inner engine enviroment you can have 150 degrees celsius (300 degree fahrenheit) very easily.

Regards, Markus
