Hitachi excavator accessory 4622945 hydraulic pump bearing (pump) 60; small bearing

This product is a cylindrical roller bearing (roller bearing) specifically designed for excavator hydraulic main pumps, which belongs to high-precision and high load-bearing capacity rolling bearings. Mainly used as the shaft support part of hydraulic pumps (such as HPV105, HPV118, A8VO200 series main pumps), it can withstand large radial loads, ensure smooth rotation of the pump shaft, reduce friction, and improve the service life and reliability of the pump. Accurately matching OEM dimensions, tightly fitting after installation, effectively supporting pump shaft rotation. Using high-quality materials and precision machining processes, it has excellent wear resistance and fatigue resistance. Capable of withstanding radial loads under high-speed and high load conditions of hydraulic pumps, reducing vibration and noise. Improve the overall efficiency and service life of hydraulic pumps, and reduce the failure rate. High quality after-sales parts have performance close to the original factory standards and high cost-effectiveness.
