Product Features & Applications

Heavy-duty Track Roller (Bottom Roller / Lower Roller) for Hitachi ZX210, ZX210LC and ZX210-5G excavators. Manufactured from high-strength alloy steel with precision machining, advanced heat treatment and heavy-duty floating seal technology. The roller supports the full operating weight of the 20-ton class excavator, guides the track chain and maintains proper undercarriage alignment during excavation, construction and earthmoving operations. Compatible with Hitachi ZX210 series excavators. Reference OEM numbers include 9184516, YA60015002, 9231278 and 9134243. Available in Single Flange (SF) and Double Flange (DF) versions according to installation position. Manufactured according to OEM-style dimensions for direct replacement with excellent wear resistance, reliable sealing performance and extended service life. Please provide your machine serial number or existing part number to confirm exact fitment.

Product Overview

The Track Roller — also known as Bottom Roller or Lower Roller — is a key undercarriage component installed beneath the track frame of Hitachi ZX210 crawler excavators.

The bottom roller carries the machine operating weight, supports the track chain and ensures smooth crawler movement during excavation, travelling and construction operations.

For a 20-ton class excavator, the track roller is continuously exposed to:

  • Heavy machine loading
  • Impact from uneven ground
  • Rock and gravel abrasion
  • Mud, dust and water contamination

A worn or damaged track roller may result in:

  • Track chain misalignment
  • Increased travelling vibration
  • Uneven track wear
  • Premature sprocket and idler wear
  • Increased maintenance costs

Our Hitachi ZX210 track rollers are manufactured according to OEM-style drawings, providing reliable aftermarket replacement solutions for construction, rental fleet and earthmoving applications.
