- Large shielded single row ball bearing. This is the main bearing fitted to all upright and laydown Norton gearbox's from the 1930's - 1950's gearbox's. This is a good quality American bearing
It is of the fully shielded variety (most originals were shielded on the outer side, but then used a seperate shielding ring on the inner side). It can either be fitted like this, or if you prefer, the shield on one side can be easily removed (email me for more details).
