This page exists to post bearing number cross references that I may help to look up from time to time. I only post it here because I have spent some significant time on such research occasionally, and as long as the information is in hand it may as well be posted rather than tossed out. The page could obviously become quite long with time, as nearly every bearing used in the MGA is a standard bearing that may have multiple manufacturers. If the bearing you have in mind is not posted here, then see the prior page for the method of discovering bearing cross reference numbers. In case you do look up more cross reference numbers, you may forward them to me, and I will endeavour to post them here to share the fruits of your efforts with others. The first number listed will be the MG or BMC or Austin factory part number as listed in the MG Service Parts List.
