Product Overview

The Track Roller, also known as Bottom Roller or Lower Roller, is an important undercarriage component installed beneath the track frame of Hyundai R80 crawler excavators.

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

For compact excavators like Hyundai R80, track rollers are exposed to:

  • Continuous machine loading
  • Uneven terrain impact
  • Soil and gravel abrasion
  • Mud and water contamination

A worn or damaged track roller may cause:

  • Track chain misalignment
  • Increased travelling vibration
  • Abnormal track noise
  • Uneven track wear
  • Accelerated wear of sprocket and idler

Our Hyundai R80 track rollers are manufactured with professional undercarriage production technology to provide reliable aftermarket replacement solutions for dealers, repair workshops and equipment owners.
