KM2118 Triple Grouser Track Shoe with 216mm Pitch and 800mm Width for Komatsu PC300 PC350 Excavator Undercarriage

Product Overview

The KM2118 Triple Grouser Track Shoe is a professional-grade undercarriage component specifically designed for Komatsu PC300 and PC350 series excavators. Manufactured from 25MnB boron alloy steel through a precision hot forging process, each track shoe delivers exceptional wear resistance and structural durability in demanding construction environments. The 800mm wide triple grouser design provides superior flotation on soft ground while maintaining excellent traction on hard surfaces. All three grouser contact surfaces are induction hardened to HRC 42-46 for extended service life. CNC-machined bolt holes ensure perfect alignment with OEM track chains, eliminating installation issues.

Key Features

• Komatsu PC Series Compatible: Precision-engineered replacement for Komatsu PC300-6, PC300-7, PC300-8MO, PC350-6, PC350-7 excavators
• Triple Grouser Configuration: Three grouser bars providing smooth ride quality, low ground pressure, and minimal surface damage on paved and hard surfaces
• Drop Forged 25MnB Steel: Full die forging process with controlled grain flow, induction hardened on all three grouser contact surfaces
• Wide 800mm Profile: Enhanced flotation on soft and wet ground conditions, reducing ground pressure for improved stability

Technical Specifications

Factory Strength

Our manufacturing facility spans over 20,000 square meters equipped with advanced forging production lines, CNC machining centers, and automated heat treatment furnaces. We operate 8 die forging hammers (1T-10T capacity), 12 CNC turning/milling machines, and 4 continuous mesh-belt quenching & tempering furnaces with precise temperature control. Annual production capacity exceeds 500,000 track shoes. Every batch undergoes rigorous quality inspection including dimensional gauging, hardness testing (HRC), ultrasonic flaw detection, and magnetic particle inspection. We hold ISO 9001:2015 and ISO 14001:2015 certifications, with SGS/Bureau Veritas third-party inspection available upon request. Our in-house metallurgical lab ensures consistent 23MnB/25MnB boron steel composition and optimal heat treatment parameters for maximum wear resistance and impact toughness.

Quality Control Process

1. Incoming raw material inspection with spectrometer analysis
2. Forging temperature monitoring and die wear inspection
3. Post-forging dimensional check on sampling basis (1 per 50 pcs)
4. Heat treatment hardness verification (HRC 40-48 on grouser surface)
5. Magnetic particle inspection for surface crack detection
6. Final dimensional inspection with go/no-go gauges
7. Anti-corrosion coating and packing inspection

Applications

Specifically designed for Komatsu PC300-6, PC300-7, PC300-8MO, PC350-6, PC350-7 excavators. Suitable for construction, trenching, material handling, and general excavation on mixed terrains.

Frequently Asked Questions

Q1: Will KM2118 fit PC300LC models?

Yes, KM2118 (TG216M-14-800) is compatible with both standard and long-carriage (LC) PC300 variants. The 216mm pitch and bolt pattern are consistent across the PC300 series.

Q2: What material certifications do you provide?

We supply Material Test Certificates (MTC) per EN 10204 3.1 standard with each shipment, detailing chemical composition, mechanical properties, and hardness values. Third-party SGS/BV inspection is available upon request.

Q3: What is your typical lead time for 100+ pieces?

Stock orders ship within 5-7 days. Production orders of 100-500 pieces typically ship within 20-25 days. For larger volumes (500+), lead time is 25-35 days depending on current production schedule.
