207-25-61100 Swing Bearing for Komatsu Excavator PC300-6 PC350-6

Restore Massive Rotational Power to Your Komatsu Dash-6

In mass excavation, quarrying, and severe-duty trenching, your 30-to-35-ton Komatsu Dash-6 excavators bear catastrophic axial and radial loads. When continuous heavy lifting causes the original swing circle to wear, it results in dangerous cab wobble, severe gear grinding, and costly downtime. Designed to meet and exceed original factory heavy-duty specifications, the 207-25-61100 Swing Bearing restores flawless, 360-degree rotational stability, getting your massive equipment back to profitable production.

The 207-25-61100 Engineering Advantage

• Exact Dash-6 Drop-In Integration:Performing a major upper-structure split on a 35-ton carrier leaves absolutely no room for guesswork. Engineered strictly to OEM blueprints, this heavy-duty swing circle replaces part numbers 207-25-61100 and 207-25-61200 without any custom fabrication. It guarantees precise bolt-hole alignment and a vibration-free pinion mesh with your existing Dash-6 swing motor.

  
  

• Mass Excavation & Quarry Ready:Whether you are pushing a standard PC300-6 in deep trenching or operating a heavier PC350-6 in a harsh rock quarry, this bearing is built to handle extreme torque. Deep-induction hardened raceways prevent premature gear spalling under maximum bucket and lifting loads.

  
  

• Severe-Duty Environmental Sealing:Equipped with robust, industrial-grade multi-lip seals that retain crucial lithium lubrication while aggressively locking out abrasive rock dust, mud, and destructive job site contaminants.
