Rhino track failier?

One question: the bearing you cited is rated for higher loads, but at much lower RPM compared with the one I was looking at. Actually neither is rated for maximum wheel speed in the Rhino drive, but the 6338K465 is closer, rated for 700 lb at 250 RPM, while the high load bearing you cited is rated for 1500 lb at 80 RPM.

Are the RPM ratings critical here? I understand that the material composition of the high load bearing makes it less susceptible to shock.

I think McMaster's ratings are highly conservative. Based on PV and V max numbers I can pull off the web, the max SFM should be 225, which translates into about 2300 RPM. Not that you could handle a full robot load at that speed. What RPM max do those Rhino Drives run at? Give me that and I can give you a max load.
