WHEEL BEARING RIGID FRAME REAR SPOOL - USE 37-0007 W7B
Rear wheel bearing for rigid-frame Triumph spool hubs, listed under 37-0007A but catalogued as superseded by 37-0007 (W7B).
This is a rear wheel bearing for rigid-frame Triumphs, listed under part number 37-0007A with the older W7A form still turning up in some parts books. The catalog note on this one points you to 37-0007 (also known as W7B) as the current part to order, so if you're working from an old book and see 37-0007A or W7A, know that the part has been carried forward under that other number.

Given the rigid frame spool-hub callout, this bearing lives in the rear wheel hub on rigid-frame machines, not the later swingarm/plunger setups. We don't have more detail on this one beyond what's in the catalog note, so if you're unsure which number applies to your hub, give the shop a call before you order and we'll sort out which bearing you actually need.
