1181-00430 Bottom Roller
Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd. supports bulk purchasing and customization of the 1181-00430 type undercarriage roller (also known as track roller), suitable for Volvo EC55 mini excavators, OEM number VOE14543561. This chassis wear part is made of high-manganese alloy steel, undergoing two heat treatments to achieve a wheel surface hardness of HRC48-55. The deep hardening layer significantly improves its wear resistance on mud, rocks, and rough terrain. A multi-layer oil seal structure effectively blocks water and sand, completely preventing oil leaks and roller jamming. CNC precision machining ensures a perfect match between the installation dimensions and original parts, allowing for direct replacement without modification. One-piece casting improves load-bearing capacity, effectively reducing track chain wear and machine downtime. Strict quality control throughout the entire process ensures stable product quality, long service life, and cost savings for global machinery dealers, repair shops, and engineering vehicle fleets.
