Bearing

There should be numbers on that bearing and the name of the manufacturer.

Reason:
thank you for the opinion, but can you please provide a reference link to a bearing that looks like mine, with that lip? and what machine it would go on?

The extra long inner race is often used for an oil seal surface. It is what BMW motorcycles use on the input shaft of the 5 speed transmission. This is a pic of a similar bearing altho I doubt it is the same bearing https://s-media-cache-ak0.pinimg.com/564x/5c/09/7e/5c097e9033656bfd7a007d948ce41b6b.jpg The link to a Web page below goes to a site that has parts diagrams for these bikes. The exploded view of the input shaft shows the bearing as part #1. It does not show the lip in this diagram but it is the bearing I showed a pic of above. I hope this helps and that the pic and links I have used worked. I'm new here and not sure how everything works. If there are any numbers on that bearing it would help immensely identifying it altho that will not tell you what it fits usually.

Reason:
Thank you for your opinion, but without any identifying marks, it is probably impossible to ID this bearing to a specific make/model/year. And the way this usually works, is if you can provide a link to the exact item online or prove without doubt what it is, we pay immediately. We've been trying since June to verify this bearing, with no luck.
