Another option would be to design in a thrust bearing and radial bearing combo. This takes alot more physical space and machining but your bearings are still inexpensive ($5) and endplay is adjustable to zero (angular contacts can be difficult to build to zero endplay).
some food for thought - mud for mudpies |
I did not mention the specs on purpose - I knew someone would ask, but I did not want to contaminate the information pool too early!
The speeds are less than 1500RPM. Loads not to exceed about 300 pounds peak dynamic thrust, 50 pounds or less radially. Precision is a concern, but not super critical, so I find either arrangement to be suitable.
The one thing I like about taper rollers for this application is that they are very stout and can be adjusted to give the desired endplay. I can't really see any reason not to use them.
All of the ideas you mention are excellent options, too!
