Different width cam bearings

[49-blues]

I bought two sets of cam bearings, 1st set is federal mogul 1755M-2 bearings are thin in width about.060" and the other 2 bearings are .075" in width. The 2nd set -TA Durabond coated cam bearings have 3- narrow bearings .060" in width and only 1 at .075" in width ---What gives? Did TA mispackage them?

i got F/M#1782"oil control" bearing set, 1 and 4 are wide, 2 and 3 are narrow. #1 has full groove on o.d.

Anyone know why the TA Durabond bearings only came with one wide bearing?

I am definately about as far from an expert on this issue as can be, but if I had to guess (and assuming they were packaged right) they gave you one wide one to disipate the load the front bearing carries and saved money (more profit) by using less material on the other three.
