@croat1 @The norm - Hey guys.....since I'm always looking for bearings I thought I'd look up the ones Joe posted.....Are you aware that those Timken Bearings specified are METRIC inner bearing and IMPERIAL outer ? No wonder everyone else with HARDKOR hubs could never find a matching set of Metric bearings for both.

Cup & Cone - 32004x = 20mm Bore 42mm OD 15mm Width https://cad.timken.com/item/tapered-roller-bearings-ts-tapered-single-/tapered-roller-bearings-ts-tapered-single-metric/32004x-2

Cup - A4138 = 34.989mm OD 8.73 Width https://cad.timken.com/item/tapered-roller-bearings---single-cups/tapered-roller-bearings---single-cups---imperial/a4138

Cone - A4059 = 14.989 Bore 10.98 Width https://cad.timken.com/item/tapered-roller-bearings---single-cones/tapered-roller-bearings-single-cones-imperial/a4059

Looks like that seal CR10937 has been Discontinued.....Here's the Replacement 28X44X6 HMSA7 P https://www.skfextranet.com/crsealsfinder/datasheet.aspx?s=28X44X6+HMSA7+P
Also, The OD of the CUP is smaller than the SEAL (44mm)

Or Does the HUB have a step...so the Seal is bigger.

Loren, can you post some pics without the bearings & seals?
