I would assume your bearings are properly lubricated. I am testing with no lubrication. So far I have found that the J type cage appears susceptible to vibration, causing metal fatigue resulting in the cage breaking apart. But I also theorize that a good grease or gear oil will suppress the vibration and the J cage will be fine under those conditions.
I have also found that the W type cage appears impervious to vibration. Is it the best all-around choice? Maybe, maybe not. But so far I am putting my money on the W type cage for my next bearing.
