Hydraulic bushings are typically made from materials such as metal or plastic, and their structure and dimensions are designed based on the relevant parameters of the hydraulic system. The primary structure of a hydraulic bushing consists of three parts: the inner surface, the outer surface, and the oil holes.
The inner surface serves as the contact interface between the bushing and the piston; it requires a high degree of smoothness and roundness.
The outer surface serves as the contact interface between the bushing and the hydraulic cylinder liner; it requires good roundness and straightness.
The oil holes are openings in the bushing that connect to the oil passages between the hydraulic pump and the hydraulic cylinder; their number and placement are determined based on specific operational requirements.
Key performance characteristics of hydraulic bushings include wear resistance, corrosion resistance, sealing capability, and cold resistance. High-quality materials and advanced manufacturing techniques should be employed during production to ensure stable performance and a long service life.
