Bearing
A bearing for the Triumph quickly detachable rear wheel hub, part number 37-1041 (also W1041).
This is a bearing used in the quickly detachable rear wheel setup, part number 37-1041, also listed under the older W1041 designation. It shows up across catalog entries running from 1960 through 1969, tied specifically to the quick-detach rear wheel arrangement rather than the standard fixed hub.

The QD rear wheel was Triumph's answer to roadside punctures — pull the wheel off without disturbing the chain or brake, and this bearing is part of what lets that hub spin freely and stay located once it's back in. Beyond that, our records don't spell out further dimensions or material for this one.
If you're rebuilding a QD rear hub, it's worth checking this against what's actually in your wheel before ordering, since the catalog data here doesn't narrow it to a specific model or year within that range. Give the shop a call if you want that confirmed.
