130104000256A021 Bearing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

130104000256A021 Bearing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130104000256A021 bearing is a key support component of the planetary transmission of the speed reducer. Working in conjunction with the sun gear, planetary gears, and pins, it withstands high-speed rotation, reduces mechanical friction, and precisely constrains the shaft’s rotation trajectory. This effectively reduces wear on components, ensures shaft concentricity, stabilizes speed reducer operation, and guarantees smooth, uninterrupted movement of the equipment during travel and rotation.
This SANY original bearing is made of high-carbon bearing steel, hardened by quenching and precision grinding, resulting in high precision and low resistance. It is suitable for harsh working conditions such as heavy loads and high-frequency vibrations. Old bearings are prone to ball wear, frame deformation, and loose clearances, causing abnormal operating noises, power interruptions, and uneven shaft wear. In severe cases, it can lead to shaft seizure and gearbox shutdown. This product can be replaced in situ without damage, suitable for equipment maintenance, overhauls, and bulk stocking, reducing component wear, extending equipment life, and lowering operating costs.
