Product Detail

Product Description: Carrier Roller 154-30-25111 for Shantui Bulldozer

The Carrier Roller 154-30-25111 is a genuine Shantui undercarriage component primarily designed for the SD22 and SD23 series bulldozers. It is also widely compatible with other Shantui models, including the SD16 and SD32. Known as the “top roller” or “support roller,” it is a critical element of the machine’s track walking system, responsible for supporting the upper strand of the track chain, reducing chain sag and vibration, and ensuring proper engagement with the drive sprocket and track idlers. This function minimizes friction between the track chain and the track frame, reduces material wear, and maintains consistent track tension, all of which contribute to stable, efficient machine operation in demanding dozing applications.
