9W9352 Single Grouser Track Shoe 188mm Pitch 900mm Width for CAT E320 Excavator Undercarriage Plate

Product Overview

The 9W9352 Single Grouser Track Shoe is a heavy-duty aftermarket undercarriage component engineered for CAT E320 series excavators. The wide 900mm single grouser configuration provides exceptional stability and ground penetration for demanding digging and trenching applications. Hot forged from 23MnB boron alloy steel, each shoe undergoes precision heat treatment with induction hardening on the grouser tip (HRC 44-48) and controlled tempering of the body for impact toughness. CNC-machined bolt holes with spot-faced seats ensure perfect mounting alignment. Every shoe is dimensionally inspected and hardness-tested before anti-corrosion coating.

Key Features

• CAT E320 Direct Fit: OEM-spec replacement for Caterpillar 9W-9352, compatible with E320, E320B, E320C model excavators
• Single Grouser Wide Profile: 900mm width with tall single grouser for maximum stability and traction in excavator digging operations
• Forged Alloy Steel: 23MnB boron steel with induction-hardened grouser tip for superior wear resistance in abrasive conditions
• Heavy-Duty Bolt Seats: Reinforced bolt seat area with spot-faced mounting surface for secure, vibration-resistant installation

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

Designed for CAT E320, E320B, E320C excavators. Suitable for heavy excavation, trenching, demolition, quarry loading, and general construction where maximum stability is required.

Frequently Asked Questions

Q1: Why choose single grouser for an excavator?

While TG is standard for excavators, SG on wide shoes provides better penetration in loose soil and improved stability on slopes. The 9W9352 900mm SG configuration is popular for E320 machines working in demanding digging conditions.

Q2: Is this compatible with E320D?

The E320D may use a different track shoe specification. Please check your existing shoe part number. The 9W9352 (SG188L-13-900) is designed for E320 through E320C series.

Q3: How many shoes do I need for a complete set?

A standard E320 uses 45-49 track shoes per side (90-98 total). Please count your existing shoes or provide your track chain link count for an accurate set quantity.
