205-25-00023 Heavy-Duty Swing Bearing for Komatsu PC200-3 PC220-3 PC240-3

Restore Legendary Power to Your Komatsu Dash-3

Classic excavators like the 20-to-24-ton Komatsu Dash-3 series remain reliable workhorses in heavy construction and agricultural earthmoving. However, decades of operation will inevitably wear down the rotational axis. When your machine develops severe upper-structure wobble or gear binding, an immediate replacement is required to save the swing motor. The 205-25-00023 Swing Bearing is heavily fortified to restore factory-level, 360-degree rotational precision to your classic Komatsu equipment.

The 205-25-00023 Performance Advantage

• Exact Drop-In Integration:Rebuilding older equipment shouldn't require custom fabrication. Engineered to strict original factory blueprints, this swing circle provides a perfect, zero-modification drop-in fit. It replaces outdated OEM part numbers like 205-25-00022 and 205-25-00021, guaranteeing exact mounting hole alignment and vibration-free pinion mesh.

  
  

• Tracked & Wheeled Compatibility:Whether you are operating a standard PC200-3 crawler in heavy dirt or utilizing a PW210-1 wheeled excavator for roadwork, this heavy-duty bearing assembly is built to withstand the unique lateral and dynamic forces of both applications.

  
  

• Severe-Duty Defense:Manufactured with deep-induction hardened raceways to prevent premature spalling under mass excavation loads. Premium environmental lip seals lock in crucial lithium lubrication while aggressively blocking out abrasive soil, mud, and debris.
