So I transplanted a W type, or crown type cage used in the double row bearings into a single row bearing and ran it at 5K for 30 minutes with no signs of cage failure, and the balls still have a mirror finish (no lubrication). I am going to take the bearing apart to examine it and then get it back on the test jig for more running.

Spinning the bearings unloaded doesn't tell you much of anything. You do realize how much engine RPM would equate to 5,000 IMS RPM, correct?
The only "jig" that works for this sort of testing or development is a running engine. Its called the M96.
