The Caterpillar 6V-5003 & 420-2498 self-aligning bearing is a precision-engineered spherical bearing designed to maintain rotational alignment in applications where shaft deflection or mounting inaccuracies may occur. Built to support both radial and axial loads, this component compensates for angular misalignment while providing smooth, reliable movement in demanding operating environments.

Used extensively in Caterpillar 525, 525C, 525D, 535B, 535C, 535D, and 545 series machinery, the Caterpillar 6V-5003 self-aligning bearing reduces vibration and stabilizes performance under heavy load. Its design allows for slight deviations in shaft alignment, ensuring continuous operation and structural integrity even in harsh conditions.

The Caterpillar 420-2498 self-aligning bearing performs a similar role, providing stable rotational alignment and vibration damping across comparable machine assemblies. Together, the 6V-5003 and 420-2498 bearings are key components for maintaining strength and extending service life in Caterpillar machines used for forestry, construction, and earthmoving applications.

Constructed from hardened alloy steel with a spherical inner race, the 6V-5003 & 420-2498 bearing ensures durability and long-term efficiency. It distributes load evenly across bearing surfaces, minimizing wear on housings and shafts. Operators experience reduced vibration, lower friction, and steady performance even when structural flexing occurs during operation.
