Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for heavy-duty commercial vehicle rear axle and wheel hub applications.
- Metric-series configuration with 65 mm bore and 145 mm outer diameter matches SKF 330633S, FAG 509333A, and Timken 509333A equivalents for direct replacement.
- Separable cup and cone construction simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated bearing steel with precision-ground raceways – designed to handle the high loads and torque demands of heavy-duty commercial vehicle drivetrains.
- Open-type configuration supports splash lubrication and oil bath systems common in heavy-duty axle and hub applications.
- Cross-referenced with Mercedes-Benz OE A0019819905 and MAN OE 06324900016 – confirmed interchange available.
Installation Notes
- Confirm bore diameter (65.00 mm) and outer diameter (145.00 mm) match your existing bearing and housing before installation.
- This bearing is designed for rear axle fitment on Mercedes-Benz and MAN commercial vehicles – confirm placement before ordering.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Set bearing preload according to Mercedes-Benz or MAN manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the manufacturer’s service manual for viscosity grade and lubrication method.
