JM714249/JM714210 Metric Tapered Roller Bearing 75x120x31mm
- Robust Dynamic Performance: The 31mm width provides an excellent contact area for the rollers, significantly increasing the dynamic load rating for heavy truck hubs.
- Super-Finished Raceways: Micro-honed contact surfaces dramatically reduce rotational noise and heat generation, protecting axle seals and lubricants.
- Separable Design: The cone and cup separate easily, allowing mechanics to set precise internal clearances during axle rebuilds.
- High Wear Resistance: Deep case-hardened steel prevents raceway pitting under continuous operational stress.
