thinking about going with green ball axle bearings

The Green vs. Timken debate is about as hotly contested as religion and politics.

Yes, Greens make for fast and easy axle installation. You'll hear people say they can install and adjust tapered bearing axles with equal speed and ease.

You'll hear the argument that Greens can't handle the side load of tapered rollers which may be true but there are also a gazillion other OEM ball bearing applications in use that seem to be doing fine.

You'll find stories of failures in both camps.

I run them as do a lot of other people. I think you'll be fine unless you do something like: install the thrust block.
