Description
Overview:
This Bottom Roller is a non-genuine replacement part for Hitachi EX29UE mini excavators. Built from heavy-duty steel with a tough, wear-resistant running surface, it supports the track chain along the lower undercarriage to keep the machine stable, aligned, and moving smoothly. The roller carries machine weight, reduces vibration, and helps maintain correct track tension during digging, grading, and travel. Designed as a direct-fit replacement for the EX29UE, it offers a cost-effective option to restore undercarriage performance without compromising reliability. Suitable for construction, landscaping, and utilities work, it helps extend the service life of the track system when paired with routine maintenance such as correct track tension and periodic inspection of pins, bushings, and seals.
