I have searched all the online suppliers i can find and nobody has the size i need. They are a 7/8 OD flange bearing with a 7/16 non threaded center. There is no manufacturer tag on the chair anywhere. Anyone have any ideas where i might be able to find them?
Bearings all have identification markings on them s a code.
This may be of assistance,
otherwise take the bearing to a bearing supplier and the will measure it and provide a replacement
