Q: Can you tell me the bearing spacing for these wheels? Regarding 06-03200
Per the supplier: I believe that you are asking for the HUB WIDTH of the 4" wide 6" Tri-Star which is 3.25" from outside of the two bearings or through the bearings. We have also added a dimensional chart to the "Documents" tab of this web page for review.
Q: Are these Azusa wheels with the Timken bearings the tapered roller bearings?
Yes, part # 06-03300 has 5/8" tapered roller bearings, and part # 06-03400 has 3/4" tapered roller bearings.
