Wheel bearing
A wheel bearing used in the front and rear wheel hubs, listed under Triumph part number 37-0653, superseding the older 37-7042.
37-0653 is a wheel bearing that shows up in the front and rear wheel sections of the Triumph parts books, with catalog appearances running 1971 to 1972. It's also known under the older factory number 37-7042, which this part number replaced, so if your parts book or an older hub still lists the earlier number, know that it's the same bearing under a new part number.

This bearing sits in the wheel hub, letting the wheel spin freely on the axle while carrying the loads from riding and braking. Because it shows up in both the front and rear wheel figures, the same basic bearing spec is used at both ends of the bike according to the catalog.
If you're chasing down a wheel bearing by an older number stamped on a hub or listed in an older parts book, check it against 37-7042 as well as 37-0653 before you order, and bring your old bearing or hub dimensions to the counter if you're not sure which one you need.
