Wheel Bearings and Headstem Bearings

I've created this page to list aftermarket wheel bearing numbers so they can be sourced from a bearing wholesaler for a lot less than they cost from a dealership for the OEM ones.

The numbers I've come up with are from using the bearing dimensions entered into the search boxes of various manufacturers. The OEM bearing dimensions came from the microfiche. Don't blame me if you buy some bearings using the information Ive supplied and you can't smash the bearing into the wheel.


Front wheel

The micro fiche lists the front wheel bearing dimensions as being 25mm ID X 52mm OD X 15mm Wide

They appear as 6205 bearings according to all the manufacturers. The OEM bearings have a contact seal on each side. I've listed the bearing numbers for the bearings with a contact seal on both sides. Each manufacturer has a different code for their seals and shields etc. A bearing with the number of 6205 is one without any shielding or seals.

The external seals that the axle spacers slide into can be purchased from a bearing wholesaler too. I haven't done any cross referencing for those yet but you should be able to purchase them by simply supplying the dimensions. According to the microfiche they're listed as being 32mm ID X 52mm OD X 7mm Wide.

The Front wheel bearing OEM part number is:
09262-25061 and is listed as a 25X52X15 Bearing.

If you need to purchase the external seals their part number is:
09285-32004 and is listed as a 32X52X7 Seal.

Rear wheel

The micro fiche lists the rear wheel bearings dimensions as being 32mm ID X 58mm OD X 13mm Wide. There is a 3rd bearing in the cush drive. It's listed as 32mm ID X 65mm OD X 17mm Wide.

They appear as 60/32 bearings for the rear wheel and 62/32 for the cush drive according to all the manufacturers that have them listed. 60/32 and 62/32 should not be confused with 6032 & 6232 bearings, they are not the same. The OEM bearings aren't sealed on both sides. I've listed the bearing numbers for the bearings with a contact seal on both sides. Each manufacturer has a different code for their seals and shields etc. A bearing with the number of 60/32 & 62/32 are ones without any shielding or seals.

The external seals that the axle spacers slide into can be purchased from a bearing wholesaler too. I haven't done any cross referencing for those yet but you should be able to purchase them by simply supplying the dimensions. According to the microfiche they're listed as being 38mm ID X 58mm OD X 7mm Wide for the right hand side of the wheel (brake side) and 39mm ID X 65mm OD X 7mm Wide for the cush drive (chain side).

The Rear wheel bearing OEM part numbers are:
09262-32008 and is listed as a 32X58X13 bearing (X2 Wheel).
09262-32007 and is listed as a 32X65X17 bearing (X1 Cush Drive).

If you need to purchase the external seals their OEM part numbers are:
09285-38001 and is listed as a 38X58X7 Seal (X1 Wheel).
09285-39001 and is listed as a 39X65X7 Seal (X1 Cush Drive).

Steering Stem bearings

The microfiche lists the Steering Stem bearings as 30mm ID X 55mm OD X 17mm Wide. I've not been able to find a generic ball bearing to replace them. The only bearing that comes up in any cross referencing is a single-row tapered roller bearing type. So if you want to run with a ball roller bearing, OEM is the only option I can find.

The taper roller bearing is a 32006. I've listed the bearing numbers from the common manufacturers that list this bearing when searching for a 30X55X17 bearing for all available configurations.

The Steering Stem bearing OEM part number is:
09267-30010 and is listed as a 30X55X17.
