China 9242963 Manufacturer, Supplier, Factory

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.

We, Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd., supply high-performance Track Adjuster Grease Cylinder for Komatsu PC200 20Y-30-29130 with strict factory inspection and stable hydraulic sealing performance. Designed for heavy-duty excavator undercarriage systems, it ensures smooth track tension adjustment, reduces downtime, and extends service life. Buyers choose our OEM-quality parts for reliable fit, fast delivery, and proven field durability in mining and construction projects worldwide.
