803149/803110 Imperial Tapered Roller Bearing 44.49x88.9x30.163mm
- Optimized Load Distribution: Crowned roller geometry prevents localized edge loading and extends the fatigue life of the raceways.
- Separable Design: The independent cone and cup configuration allows mechanics to quickly set precise end-play during equipment overhauls.
- Low Frictional Torque: Micro-polished contact surfaces minimize heat generation and rotational drag, protecting drive lubricants.
- Impact Resilience: Deeply case-hardened steel absorbs sudden shock loads common in off-road and agricultural use.
