Brand: GLOBALMACHEX
SKU: 708-8H-32170
Availability: InStock
Rating: 5 (1 reviews)

708-8H-32170 tapered roller bearing is a special replacement part for medium Komatsu excavators including PC270-8, PC290-10, PC308USLC-3E0, PC300-8MO, PC350-8MO and PC360-7, mainly installed on hydraulic pump and slewing reduction transmission positions. Precisely manufactured from GCr15 bearing steel with optional P0/P6/P5 precision grades, it can bear combined radial and axial loads with great wear and impact resistance, adapting to alternating heavy loads in earthwork and mining operations. It can directly replace OEM bearings, serving as a key wearable bearing for maintenance and overhaul of hydraulic and slewing systems of medium excavators.

贸易信息

1. Product Overview

The 708-8H-32170 tapered roller bearing is developed for mainstream medium Komatsu excavators from PC270 to PC360 series with fully OEM-matched dimensions. It is mounted on transmission parts of main hydraulic pump and slewing reducer, enduring impact and alternating composite loads in excavation work, acting as a core matching part 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, it features uniform hardness on rollers and raceways for excellent anti-fatigue and wear performance. The tapered structure distributes radial and axial loads to adapt to frequent start-stop operation and variable working loads. Split inner and outer rings facilitate disassembly to shorten maintenance downtime 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 continuous mining 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 708-8H-32170 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.
