708-1W-42120 Tapered Roller Bearing for Komatsu Excavator PC600LC-8 PC650-8EO PC700-8 PC800-8E0 PC850-8EO Replacement Spare Parts

708-1W-42120 tapered roller bearing is a dedicated replacement part for large Komatsu excavators PC600LC-8, PC650-8EO, PC700-8, PC800-8E0 and PC850-8EO, mainly used for hydraulic pump and slewing transmission assemblies. Precision made of GCr15 bearing steel with optional P0/P6/P5 precision grades, it can bear combined radial and axial loads with outstanding wear and impact resistance, adapting to alternating heavy loads during excavation. It can directly replace OEM bearings on site, serving as a key wearable component for maintenance and overhaul of hydraulic and slewing systems of large excavators.

1. Product Overview

The 708-1W-42120 tapered roller bearing is designed for large Komatsu excavators from PC600 to PC850 series with fully OEM-compliant dimensions. It is installed on transmission positions of main hydraulic pump and slewing reducer, enduring impact and alternating composite loads during excavation, and acts as a core matching bearing for maintenance of excavator hydraulic and slewing mechanisms.

2. Material & Processing Advantages

Made of standard GCr15 high-carbon chromium bearing steel with precise quenching and tempering heat treatment, the rollers and raceways feature uniform hardness for excellent anti-fatigue and wear performance. The tapered structure distributes radial and axial loads to suit heavy start-stop operation and variable loads of large excavators. Split inner and outer rings simplify disassembly to cut maintenance downtime and construction delay losses effectively.

3. Precision Grade Options

  • P0: Cost-effective standard option for regular site maintenance and ordinary earthwork construction
  • P6: Tighter machining tolerance reduces vibration and heat generation, ideal for heavy continuous mining operation
  • P5: High-precision specification for complete machine overhaul and hydraulic/slewing system performance upgrade for smoother operation

4. Quality & Installation Instruction

Manufactured strictly following original 708-1W-42120 specifications for direct on-site replacement without secondary machining. Every bearing passes full inspection on clearance, hardness and appearance before delivery. Custom precision grades are available for bulk orders to lower installation failure risks.

5. Application Scenarios

It is widely applied for overhaul of matched large Komatsu excavators, export wholesale of construction machinery spare parts, daily maintenance of excavator fleets for mining and large infrastructure projects, solving common problems including abnormal noise, looseness, transmission shake and load capacity degradation of original bearings.
