The 9114275 Track Roller is a durable undercarriage component designed for the Hitachi EX400 Excavator. Also known as a bottom roller or lower roller, it supports the track chain and helps maintain stable crawler movement during excavation, transportation, and heavy-duty earthmoving operations.

Xiamen Doozer supplies 9114275 Track Rollers for Hitachi EX400 excavators as aftermarket replacement undercarriage parts. Industry parts references identify 9114275 as a track roller for the EX400, making it a suitable reference number for sourcing and replacement.

The track roller is manufactured with a heavy-duty steel construction designed to withstand continuous loads, vibration, impact, and abrasive working environments. Its robust structure helps support the machine through demanding applications such as construction, mining, quarrying, and large-scale excavation.

A properly functioning track roller helps distribute the excavator’s weight through the crawler system while guiding the track chain along the undercarriage. Precision machining helps maintain consistent dimensions and proper alignment with the track chain and other undercarriage components.

Track rollers are exposed to constant pressure and contact during machine operation. Excessive wear, damaged running surfaces, abnormal noise, or oil leakage may indicate that a roller requires inspection or replacement. Timely replacement of a worn Hitachi EX400 track roller can help maintain stable track movement and reduce additional wear on the track chain and related components.

We support distributors, contractors, repair workshops, and heavy equipment parts dealers with factory-direct aftermarket supply.
