12749/10 Wheel Bearing For TOYOTA
The DUHUI Bearing LM12749/10 wheel bearing is an inch-series single-row tapered roller bearing assembly consisting of a cone (inner ring) and cup (outer ring). With a 21.986 mm bore, 45.237 mm outer diameter, and 15.494 mm total width, this bearing supports combined radial and axial loads in automotive wheel hub and drivetrain applications. It matches Toyota OE specifications including 90080-36075 and 90368-22001, and is cross-referenced with Timken LM12749/LM12710, NSK LM12749/LM12710, and NTN 4T-LM12749/10.

Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for automotive wheel hub and drivetrain applications.
- Inch-series configuration with 21.986 mm bore and 45.237 mm outer diameter matches Timken LM12749/LM12710, NSK LM12749/LM12710, and Toyota OE 90368-22001 for direct replacement.
- Separable cup and cone construction (LM12749 cone / LM12710 cup) simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated GCr15 bearing steel with precision-ground raceways – rated for 36.0 kN dynamic load and 33.5 kN static load.
- Cross-referenced with Toyota OE 90080-36075 and 97770-12749 – confirmed interchange available.
Installation Notes
- Confirm bore diameter (21.986 mm) and outer diameter (45.237 mm) match your existing bearing and housing before installation.
- This bearing is a combination of cone (LM12749) and cup (LM12710) – the cone includes the inner ring with cage and roller set, while the cup is the outer ring.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Single-row tapered roller bearings must be mounted in mirror-image arrangement with a second tapered roller bearing to accommodate axial loads in both directions.
- Lubricate with high-quality wheel bearing grease and torque all fasteners to vehicle manufacturer specifications.
