The Hydraulic Pump Bushing is a cylindrical sleeve component used to support and guide the rotating shaft inside a hydraulic pump. Its primary role is to reduce friction between the shaft and the pump housing while maintaining proper alignment during operation. This helps ensure smooth rotation, reduces wear on mating surfaces, and improves the overall efficiency and lifespan of the pump.Attributes:• High wear and load resistance.• Withstand high pressure and thermal resistance.Applications: The Hydraulic Pump Bushing is located inside the housing of hydraulic pumps to support and guide the rotating shaft, reducing friction and maintaining shaft alignment under load.
