Product Introduction
The L814749/L814710 is a light-series imperial tapered roller bearing featuring a large 76.2 mm (3-inch) inner bore combined with a thin 19.05 mm cross-sectional width. Sized at 76.2 x 109.538 x 19.05 mm, this specific "L" (Light) series bearing is engineered for applications where large shaft diameters are necessary, but housing space and weight must be minimized. Manufactured from premium vacuum-degassed chrome steel, it delivers high rotational precision and stiffness without adding unnecessary bulk, making it ideal for compact drive assemblies.
Applications
Light-duty industrial transmissions and gearboxes.
Specialized agricultural machinery and implement hubs.
Precision large-diameter rotary index tables.
