Aftermarket 20y-25-11103 Swing Bearing for Komatsu PC200-5 PC200LC-5 PC220-5 PC220LC-5

Restore Precision to Your Classic Komatsu Dash-5

The 20-to-24-ton Komatsu Dash-5 excavators are legendary for their durability in severe earthmoving and forestry applications. However, decades of rigorous swinging will inevitably degrade the rotational axis. When your machine suffers from upper-structure binding, dangerous cab wobble, or grinding gears, a premium replacement is required. The 20Y-25-11103 Swing Bearing restores factory-level 360-degree rotational stability, extending the profitable lifespan of your classic Komatsu iron.

The 20Y-25-11103 Engineering Advantage

• Zero-Modification Drop-In Fit:Rebuilding classic equipment demands absolute dimensional accuracy. Engineered strictly to OEM blueprints, this heavy-duty swing circle replaces part numbers 20Y-25-11103, 20Y-25-11100, and 20Y-25-11101 without any need for custom adapters. The mounting holes and pinion mesh perfectly align with your existing Dash-5 swing motor.

  
  

• Mass Excavation Endurance:Built to handle the immense lateral torque of 24-ton carriers like the PC240-5K and the rapid trenching cycles of the PC200-5. It features deep-induction hardened raceways designed to prevent premature spalling and gear tooth stripping under maximum bucket loads.

  
  

• Heavy-Duty Environmental Sealing:Equipped with industrial-grade lip seals that retain crucial lithium grease while aggressively locking out abrasive job site contaminants such as mud, rock dust, and water.
