150201020088B003 Tapered Roller Bearing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150201020088B003 boasts four major advantages: high load capacity, impact resistance, wear resistance, and stability. It is widely used in heavy equipment such as cranes, hydraulic motors, and mining equipment, undertaking the load-bearing and guiding functions of the transmission system. Through the precise matching of rollers and raceways, it disperses radial and axial loads, ensuring high-speed and stable operation of the equipment, preventing bearing jamming and excessive wear, adapting to various models, and being easy to install and put into use directly.
This product is made of high-quality materials and precision-machined, strictly adhering to industrial bearing quality standards. The inner and outer rings and rollers are made of GCr15 high-carbon chromium bearing steel, precision forged, heat-treated, and precision ground. The raceway features a logarithmic curve design and is hardened, resulting in excellent impact resistance, wear resistance, and fatigue resistance. It effectively solves problems such as bearing jamming and raceway wear, reducing maintenance costs and extending equipment life. Its double-row structure increases load-bearing capacity by more than 30% compared to a single-row structure, making it suitable for high-speed, high-load, and high-impact operating conditions, meeting the core requirements of industrial equipment.
