EE380080-380190 bearing

Products Features

The EE380080/380190 Tapered Roller Bearing is a single-row imperial standard component, recognized for its robustness in demanding industrial applications. As one of the most widely utilized bearing types, this assembly efficiently manages both significant radial and axial loads simultaneously. Its design features two separable main parts: the cone (inner ring assembly, EE380080) and the cup (outer ring, 380190), simplifying installation and maintenance. Manufactured from high-quality materials like Chrome Steel and featuring Pin-Type cage construction, the EE380080/380190 delivers reliable, low-friction operation, ensuring extended uptime across heavy-duty equipment.

Specifically engineered for high-load capacity, the EE380080/380190 bearing is a critical component in numerous sectors. Typical applications include gearing systems and transmissions, heavy-duty mining equipment, port machinery, and large-scale power generation coal transporters. With an impressive 8-inch bore diameter and 19-inch outer diameter, this bearing assembly is often mounted in opposing pairs to handle thrust loads from either direction effectively. Choosing the genuine EE380080/380190 ensures reliable support and sustained performance for the most challenging operational environments where precision and durability are non-negotiable.
