EX210 Track Roller 9181373, Bottom Roller With Integral Forging For EX210 Excavator Undercarriage Load Bearing Replacement
Product Overview
This 9181373 EX210 bottom track roller is a high-load undercarriage load-bearing component designed for EX210 series excavator track system replacement and daily construction maintenance. Different from common spliced, welded or cast track rollers circulating in the aftermarket, this lower roller adopts professional one-piece integral forging process. The integrated roller body features denser internal metal structure, better overall toughness and stronger anti-pressure capacity, perfectly coping with continuous track load, ground impact and long-hour vibration during daily excavation work. As a direct undercarriage manufacturer, we implement full-process forging inspection to eliminate internal structural defects and guarantee stable long-term load-bearing performance.
Technical Specifications (Factory Verified Exact Data)
Parameter Item Factory Standard Specification
Part Number 9181373
Applicable Equipment EX210 Series Excavator
Core Craft Integral One-piece Forging
Post-processing Precision Machining + Stress Relief + Hardening Heat Treatment
Surface Hardness HRC 52-58
Dimensional Tolerance ±0.02mm
Structural Feature Seamless body, no welding joints, high compression resistance
Working Scenarios Earthwork excavation, road construction, general muddy and uneven sites
Differentiated Integral Forging Quality Control
Most low-cost bottom rollers adopt split welding or ordinary casting craft, which leave inherent welding seams and internal pores. These hidden defects will expand gradually under long-term chassis load and vibration, causing roller cracking, oil leakage and premature failure. Our 9181373 track roller adopts complete integral forging forming without any splicing or welding. Every finished roller passes ultrasonic nondestructive testing to check internal compactness, ensuring no hidden structural flaws inside the roller body. This forging-focused quality control solves the core durability problem of assembled cast rollers for daily construction load-bearing work.
Core Product Advantages
  • Seamless Integral Forged Structure: One-piece forming removes welding seam weakness points, effectively resisting heavy pressure and vibration impact without roller cracking or deformation.
  • Higher Internal Structural Density: Forged material owns tighter metal texture than cast parts, improving overall fatigue resistance for long-time continuous operation.
  • Stable Sealing Performance: Integrated roller body fits internal oil seal structure better, reducing oil leakage risk and extending service life of internal rotating parts.
  • Full Standard Size Compliance: Strictly produced per 9181373 official dimension standards, supporting direct bolt-on replacement without field modification.
Packaging & Factory Service
This integral forged bottom roller is perfectly matched for EX210 series excavator undercarriage load-bearing replacement and routine equipment overhaul. Each roller is protected with anti-rust oil and waterproof film, then packed with thickened wooden boxes to avoid collision damage during long-distance sea transportation. We support forging process inspection records, sample testing and bulk customized orders, providing high-structure-durability undercarriage spare parts for global equipment wholesalers and repair workshops.
