Automotive & Vehicle Fitment
The KOYO HC32210JR is widely used as a wheel hub or axle bearing on many commercial truck and bus applications as well as some European-market vans. It aligns with engineering OEM reference numbers used by manufacturers such as Isuzu, Mazda, and Nissan — meaning it’s a direct replacement in those vehicles when the OEM bearing part number matches.
🚗 Known OEM Cross-Reference Part Numbers
These OEM codes correspond to systems that require a 50 mm × 90 mm × 24.75 mm tapered roller bearing:
-
ISUZU: 8-94248-088-2, 9-88450-110-0, 8-94368-553-1
-
MAZDA: 0540-27-350, Z501-17-205
-
NISSAN: 38140-30K00, 40210-89TA7, 402100T100
(Use OEM part numbers to verify exact year/model fitment — see your vehicle’s parts catalog.)
Vehicle Fitment Examples
Based on cross-reference data and parts catalogs, HC32210JR fits these example vehicles and assemblies where the specified OEM part numbers are used:
✅ ISUZU Vehicles
-
Isuzu commercial truck models where the OEM hub bearing codes above are specified (various N-series and F-series fits)
✅ MAZDA Models
-
Mazda trucks and vans that share wheel bearing OEM references (e.g., Mazda B-series/Titan) with corresponding part numbers
✅ NISSAN Applications
-
Nissan light-commercial vehicles (e.g., Cabstar / Trade / UD series) that use similar hub bearing part specs
✅ IVECO & Mercedes-Benz (Fitment Listings)
Some listings also show compatibility with:
-
IVECO MK series trucks (1980s–1990s)
-
Mercedes-Benz O 309 buses (1968–1989)
(Fitment available where OEM part codes are equivalent.)
⚠ Final confirmation should always be done by matching your vehicle’s OEM bearing part number to the bearing you’re ordering.
