Rating: 5 (1 reviews)

708-1W-42110 tapered roller bearing is a dedicated replacement part for large Komatsu excavators PC600-8EO, PC650-8EO and PC700-8EO, mainly applied to hydraulic pump and slewing transmission positions. Precision manufactured from GCr15 bearing steel with optional P0/P6/P5 precision grades, it bears combined radial and axial loads with good wear and impact resistance to adapt to alternating heavy loads during excavation work. It can be installed directly to replace OEM original bearings, acting as a key wearable bearing for overhaul and maintenance of excavator hydraulic and slewing systems.

Informacion comercial

1. Product Overview

The 708-1W-42110 tapered roller bearing is customized for large Komatsu excavator models PC600/PC650/PC700-8EO with fully OEM-matched dimensions. It is installed inside the main hydraulic pump and slewing reduction gear assembly, enduring combined impact loads from excavation operations, and serves as a core matching part for maintenance of hydraulic and slewing mechanisms.

2. Material & Processing Advantages

Made of standard GCr15 high-carbon chromium bearing steel with precise quenching and tempering treatment, it delivers uniform hardness on rollers and raceways for great anti-fatigue and wear performance. The tapered structure distributes radial and axial loads to adapt to frequent start-stop operation and variable loads of excavators. Split inner and outer rings simplify disassembly to cut downtime of large excavators and reduce construction delay losses.

3. Precision Grade Options

P0: Cost-effective standard choice for regular site maintenance and ordinary earthwork operation
P6: Tighter tolerance reduces vibration and heat generation, ideal for heavy-duty continuous construction
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-42110 specifications for direct 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 minimize installation failure risks.

5. Application Scenarios

It is widely used for overhaul of matched Komatsu excavators, export wholesale of construction machinery spare parts, daily fleet maintenance for mining and large infrastructure projects, solving common defects including noisy looseness, axial play, transmission shake and load capacity decline of original bearings.
