Bearing Sizes?

Hey guys I was wondering if anyone could shed some light on how BMW lists bearings. I see that the headset bearings for a R80/7 is listed to be the same upper and lower. The description shows them as being 28x52x16. Does this mean that they are 28mm ID, 52mm OD and 16mm tall? As usual any insight is appreciated, thanks!
Tim

Those numbers do represent the sizes as you suggest.

There's a bearing class going on right now in another thread.

These are about the cheapest around. Price is for a pair.

Price

I believe 28x52x16 is how you calculate the dealer price - to two decimal places. $232.96.
Installation is an additional 36x24x36.

I'd stay away from All Balls. They are cheap & do carry a wide range applicable to M/cycles. They are well marketted. But unfortunately their quality sucks & they don't tend to last. Better to use name brands. I'd suggest the wholesaler & dealers like All Balls because of the marketing, distribution, & because they get a good mark up.

Am I a shill for cycleworks?

Cycleworks sells that very same steering head bearing- which is used in all airheads from 1970: http://www.cycleworks.net/index.php?...roducts_id=200

A quick google of the bearing numbers 320/80 yields: http://www.astbearings.com/product.html?product=320_28


I am not sure if I am a subconscious shill for Cycleworks or just really appreciate their lack of bullshit. Good luck!
