If there is a Timken short bearing, I would be surprised if there is not a Timken long bearing. Long a believer in Timken.
Edit: The Timken number seems to be in error as it specifies a taper cone bearing.
Rather, working backwards from a 93328 Hyatt I come to
https://www.yoyopart.com/oem/11469267/hyatt-93328.html which has an interchange of:
DT Components J241256
Precision Seals & Bearings J241256
STUDEBAKER 175365
STUDEBAKER 176365
IHC 62772D
TIMKEN J241256
One could probably do the same for the long bearing.
