YNF17255 561-50-82310 Spherical Roller Bearing Heavy-Duty Excavator Bearing for Swing and Travel Systems

The YNF17255 561-50-82310 spherical roller bearing is specifically engineered for Komatsu excavators, commonly used in swing gearboxes, travel motors, and drivetrain assemblies. Designed to carry heavy radial and axial loads, this spherical roller bearing also compensates for shaft misalignment, ensuring stable and smooth operation.

Constructed from high-quality bearing steel, the YNF17255 offers exceptional resistance to wear, fatigue, and corrosion. Its precision machining allows it to handle shock loads and extreme working conditions typically encountered in excavation.

As an OEM-equivalent aftermarket replacement, the YNF17255 bearing provides reliable performance at a cost-effective price point. By replacing worn bearings, excavator operators can prevent system failures, reduce downtime, and extend the service life of swing and travel systems.
