Product Features & Applications

Heavy-duty Track Roller (Bottom Roller / Lower Roller) for Hitachi RH108 excavators. Manufactured from high-strength alloy steel with precision machining, advanced heat treatment and heavy-duty floating seal technology. The roller supports the machine weight, guides the track chain and maintains stable undercarriage performance during excavation and earthmoving operations. Designed for Hitachi RH108 crawler excavators with OEM-style dimensions, our track rollers provide excellent wear resistance, reliable sealing performance and long service life. Available in Single Flange (SF) and Double Flange (DF) versions according to track frame position. Manufactured using high-quality alloy steel, professional heat treatment and strict inspection processes to ensure reliable aftermarket replacement performance. Please provide your machine serial number, existing OEM part number or installation dimensions 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 RH108 crawler excavators.

The bottom roller carries the machine operating weight, supports the track chain and maintains correct crawler alignment during travelling and excavation.

During operation, the roller is exposed to:

  • Continuous machine loading
  • Impact from uneven terrain
  • Soil and gravel abrasion
  • Mud and water contamination

A worn or damaged track roller may cause:

  • Track chain misalignment
  • Excessive vibration
  • Uneven track wear
  • Increased maintenance cost
  • Reduced machine working efficiency

Our RH108 track rollers are manufactured according to OEM-style production standards, providing reliable replacement solutions for equipment dealers, repair workshops and contractors.
