To determine the bearing model you need in the absence of part codes, start by taking accurate measurements of the bearing: outer diameter (OD), inner diameter (ID) and height (H). In the case of headset bearings, also measure the inner and outer chamfer angles. Input these measurements into the filters to refine your search.
