Has anyone figured out a good replacement for Eldorado Bridgemill Spindle Bearings? One that could handle 6000 Rpms?
I finally toasted mine at 4500 rpms. Running my 2.5hp treadmill dc motor. These open cage Wheel bearings are a pain. Since there's no real good way to keep the grease in them.( as it warms up the grease slowly makes it way out) Anybody try using sealed bearings? I can't see what the difference may be.
