Product Description

Restore Smooth Operation to Your Komatsu Dash-6

When your 10-to-13-ton Komatsu excavator or crawler carrier begins to experience excessive upper-structure play, grinding noises, or metal shavings in the grease, it is time for an immediate swing circle replacement. The 203-25-61101 Swing Bearing is engineered specifically for the dynamic loads of Komatsu Dash-6 series machines, resolving rough rotation and preventing costly collateral damage to your swing motor.

The 203-25-61101 Advantage

Exact Drop-In Fitment: Engineered to mirror OEM blueprints, this bearing assembly is a direct, zero-modification replacement for part numbers 203-25-61101 and 203-25-61100. Alignment pins, bolt hole patterns, and pinion gear mesh are 100% factory-spec.
Urban & Confined-Space Ready: Extensively used in zero-tail-swing excavators (like the PC128US-1) and rotating crawler carriers (CD110R). It features deep-induction hardened raceways designed to handle the continuous, rapid rotational cycles typical of urban trenching and site prep.
Heavy-Duty Sealing: Equipped with robust environmental lip seals that retain crucial lubrication while aggressively locking out abrasive construction dust, mud, and debris.
