NORTON MAIN BEARING TAIWAN (C3 ROLLER) - Replaces NM17824
A Taiwan-made C3 roller main bearing for Norton engines, cataloged as the replacement for factory number NM17824.
This is a main bearing for the Norton engine, listed as a roller bearing with C3 clearance, made in Taiwan. It's cataloged as a replacement for the older factory number NM17824, so if your parts book or an old bearing case shows that number, this is the current equivalent.

Main bearings carry the crankshaft in the cases and take the load from both the running engine and the drive it's putting out, so they're not a part to guess on. We don't have more detail on this one beyond what's above, so give us a call and we'll confirm it's the right fit for your engine before you order.
Note this is a Norton part, not a Triumph one — it's built for the Norton engine family, not any of the unit or pre-unit Triumph twins we usually stock.
