TG203C Triple Grouser Track Shoe 203mm Pitch Forged 23MnB Boron Steel Undercarriage Plate for Excavators and Bulldozers

Product Overview

The TG203C Triple Grouser Track Shoe is our most versatile undercarriage product, designed with a 203mm pitch — the industry's most widely used track chain dimension. This universal-fit shoe serves an extensive range of excavator and bulldozer models from CAT, Komatsu, Hitachi, and other major manufacturers. Forged from 23MnB boron alloy steel, each shoe delivers reliable performance through induction-hardened grouser surfaces (HRC 42-46) and a balanced 700mm width that provides both stability and maneuverability. The triple grouser configuration ensures smooth operation across diverse applications from construction to agriculture. An ideal stocking item for equipment dealers and fleet operators managing mixed-brand machine inventories.

• Universal Cross-Platform Design: 203mm pitch fits both popular excavator and bulldozer models — exceptional interchangeability across CAT, Komatsu, and Hitachi equipment
• Triple Grouser All-Terrain: Versatile TG configuration suitable for construction, earthmoving, agricultural, and mixed-terrain applications
• Forged 23MnB Steel: Cost-effective yet durable boron alloy steel with induction hardening on all grouser surfaces for consistent wear life
• Wide 700mm Platform: Generous width providing excellent stability and flotation across diverse ground conditions

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.

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

Universal fitment for 203mm pitch excavators and bulldozers. Compatible models include: CAT D6 series, CAT 320/325, Komatsu D65, PC200, Hitachi EX200, ZX200, and various Chinese brand equipment. Applications: general construction, road building, agriculture, forestry, and mixed-terrain earthmoving.

The TG203C-13-700 fits any crawler machine using 203mm pitch track chains with standard 4-bolt M20 mounting. The 203mm pitch is one of the most common sizes, used by many CAT, Komatsu, and Hitachi models. Always verify your machine's pitch measurement.

Yes, we specialize in mixed-container orders. You can combine different track shoe sizes, undercarriage rollers, idlers, sprockets, and GET parts for efficient container consolidation and lower per-unit shipping costs.
