13624157 Sany SY485C1 hydraulic excavator slewing bearing

The slewing bearing (13624157) of the SANY SY485C1 hydraulic excavator is a key component connecting the upper and lower bodies of the excavator. Also known as the “slewing turntable,” it is manufactured strictly according to SANY’s original design standards, material requirements, and process specifications. It is specifically designed for harsh working conditions involving heavy loads, high-frequency rotation, and strong vibrations, such as in mining, infrastructure construction, and earthmoving. As the core assembly that transmits slewing torque and bears the machine’s vertical, horizontal, and overturning loads, it directly determines the smoothness and accuracy of the equipment’s slewing motion. It is a crucial original equipment manufacturer (OEM) part for the maintenance, overhaul, and performance restoration of the SY485C1 excavator.

This slewing bearing is integrally forged from high-strength alloy structural steel. The raceway undergoes quenching hardening and precision grinding, resulting in high hardness, strong wear resistance, and excellent contact fatigue strength. It can withstand heavy loads and high-frequency rotational impacts for extended periods and is not prone to pitting, wear, or deformation. Internally, it employs high-precision rolling elements (steel balls/rollers) and an optimized raceway design, ensuring precise clearance control, low rotational resistance, and flexible rotation. Combined with original equipment manufacturer (OEM) gear tooth profile machining, it provides smooth meshing and low noise, enabling precise positioning and smooth rotation of the upper chassis, thus improving operational efficiency. Simultaneously, it features a double-sealing structure and a long-lasting lubrication channel. Specialized seals are resistant to high and low temperatures and aging, effectively preventing dust, mud, and impurities from entering, preventing grease leakage, and extending service life. The convenient lubrication channel design facilitates daily maintenance.

The product’s mounting hole positions, bolt specifications, and gear parameters strictly adhere to OEM standards, perfectly matching the SY485C1 excavator’s swing motor, upper chassis, and lower chassis. Precise positioning and simple assembly allow for quick installation without additional processing or adjustments, rapidly restoring the equipment’s swing transmission performance and ensuring continuous operation.
