The KOYO 32215JR Tapered Roller Bearing is a high-quality single-row tapered roller bearing designed to handle combined radial and axial loads in demanding automotive and industrial applications. Built to ISO metric standards with precision steel construction, this bearing delivers reliable performance and long service life in wheel hubs, drivetrain assemblies, and heavy-load machinery.

Technical Specifications

This bearing features a separable cone and cup design, allowing precise mounting and preload adjustment in paired applications.

Vehicle Compatibility & Fitment

The KOYO 32215JR is widely used as a wheel hub / rear axle bearing and in other drivetrain assemblies where the OEM specifies this size bearing or its cross references. Cross-reference data from automotive parts catalogs shows compatibility with multiple manufacturers and part numbers.

Common OEM Reference Part Numbers

These OEM codes are known to match the bearing size and are often listed in automotive parts systems:

• HINO: SZ366-75012, 99332-2150, 98847-5101

• ISUZU: 9-00093-161-0, 1-09812-044-0, 1-09812-053-0

• MAZDA: 9960-32-215

• MITSUBISHI: MS556519, MH043149, MH043044

• NISSAN: 43210-L0700

• TOYOTA: 90033-66030

Vehicle Fitment Examples

This bearing size is commonly used in heavy-duty and medium-duty commercial vehicles, especially in wheel suspension and axle/drivetrain mounting points:

✔ HINO Trucks

• 195 Light-Duty

• 300 Series

• 500 Series

• Dutro
  (Used in rear axle/wheel hub assemblies where OEM codes above are specified.)

✔ ISUZU Trucks & Buses

• Forward / Truck chassis models requiring matching OEM bearing numbers.

✔ MAZDA

• Titan (rear hub / drivetrain applications).

✔ MITSUBISHI

• Canter

• Fighter FK

• Fighter Mignon

• Fuso Truck

• Fuso Truck FK
  (Fits rear axle / transmission bearing where OEM numbers above apply.)

✔ NISSAN & TOYOTA

• Models like Toyota Dyna, Toyo Ace, and Nissan Diesel vehicles where the matching OEM bearing codes are used fit this bearing size.

⚠ Fitment Precision: Final vehicle fitment must be verified by matching the OEM part number in the vehicle’s parts catalog or VIN lookup — the generic bearing code 32215JR is a dimensional identifier, not a direct OEM model number.

Applications & Where It’s Used

🚗 Automotive / Commercial Vehicles

• Wheel hub / axle bearings

• Rear axle transmission supports

• Differential pinion bearings
  When vehicle service manuals or OEM parts catalogs specify one of the cross reference part numbers above, the KOYO 32215JR provides the correct tapered roller bearing size for the assembly.

🏭 Industrial & Mechanical

Beyond automotive, this bearing is suitable for:

• Heavy machinery drive shafts

• Gearboxes & reducers

• Construction and agricultural equipment

• Industrial rotating assemblies
  The tapered roller design supports combined radial and thrust loads reliably in high-load systems.

Key Features & Benefits

✔ Heavy-Duty Load Support: High dynamic and static capacity for demanding applications.
✔ Separable Design: Allows easy installation and preload/clearance adjustment.
✔ ISO Metric Standard: Interchangeable with other brand bearings of the same size.
✔ Versatile Usage: Fits automotive wheel hubs and industrial rotating shafts alike.
✔ Durable Construction: Precision steel rollers and raceways for long service life.
