120301140260C Rolling bearing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 120301140260C rolling bearing, relying on professional equipment manufacturing technology and strictly adhering to industry standards and quality control systems, is specially designed for the harsh working conditions of construction machinery. It is widely used in major construction machinery models such as excavators, crawler cranes, and pump trucks, and is suitable for various complex operating scenarios such as mining, infrastructure, and construction. It effectively solves industry pain points such as bearing jamming, excessive wear, and excessive noise, helping equipment improve operating efficiency and extend the service life of the entire machine. It is a core preferred part for maintenance and replacement in the construction machinery aftermarket, and is also one of the popular high-quality parts for foreign trade exports and parts wholesale.
As a “key connecting component” in the rotating system of engineering machinery, this rolling bearing is meticulously selected in terms of material selection and processing. It uses high-quality GCr15 bearing steel and undergoes multiple processing steps such as quenching, precision grinding, and polishing, resulting in a surface hardness of HRC60-65. This ensures that the bearing has excellent wear resistance, contact fatigue strength, and impact toughness, effectively avoiding failure problems such as plastic deformation and fatigue pitting. At the same time, the inner and outer ring raceway design is optimized, and it is equipped with high-precision rolling elements and cages to reduce operating friction and noise. It is suitable for complex operation requirements such as high speed and heavy load, and can operate stably in harsh working conditions for a long time.
