OIL SEAL,BSA B50 SWING ARM
Swinging arm pivot oil seal for the BSA B50, catalog part 83-2244 (alias F12244).
This is an oil seal for the swinging arm pivot, listed in the catalog under the BSA B50. The catalog entry ties it to the SWINGING ARM AND SUSPENSION UNITS figure, so it lives at the pivot point where the rear swinging arm meets the frame, keeping grease in and dirt out of the pivot bushing.

The alias F12244 is the older factory-style number for this same seal. Our record only shows this part appearing once, tied to 1971, so we don't have more history on it beyond that single catalog listing.
This is a BSA part, not a Triumph part, despite how it's filed in our system. If you're working on a B50 swinging arm and need the pivot seal, this is the one — but call ahead to confirm it matches what's on your bike before you order.
