Reduces Friction and Handles High Hydraulic Pressure
Hydraulic systems operate under high pressure and continuous motion, requiring components with excellent wear resistance and stability. We have been manufacturing hydraulic components since 2011 and have supplied bushing systems to Sany Heavy Industry, whose hydraulic systems operate under demanding load conditions. This experience supports our capability in precision wear components.
This Hydraulic Pin and Bushing is used in robot joint cylinders, automated hydraulic stations, servo cylinders, and precision hydraulic units. It is designed to reduce friction while maintaining structural stability under high pressure.
Materials include tin bronze, high-strength brass, 40Cr alloy steel, and powder metallurgy wear-resistant materials, ensuring long service life and stable performance.
Precision Performance for High-Pressure Applications
Our machining processes ensure high dimensional accuracy and stable fitting performance.
This Hydraulic Pin and Bushing features an inner diameter tolerance of IT6–IT7 grade and surface roughness of Ra ≤ 0.8 μm, ensuring smooth movement and reduced wear.
The fit clearance is controlled between 0.01–0.05 mm for optimal lubrication and motion performance.
It is designed to withstand a rated working pressure of up to 35 MPa. Wall thickness ranges from 2–10 mm depending on application requirements.
The operating temperature range is -30°C to 120°C. Surface treatments include phosphate coating, anti-rust oil, and hard chrome plating for enhanced durability and corrosion resistance.
Durable Hydraulic Wear Component for Industrial Systems
We provide more than components-we deliver long-life solutions for hydraulic motion systems.
This Hydraulic Pin and Bushing is suitable for operation in hydraulic oil and lubricating oil environments.
It is widely used in robot joint cylinders, servo hydraulic units, automation hydraulic modules, and construction machinery hydraulic systems.
With over a decade of experience since 2011, we are committed to producing reliable hydraulic wear components that support stable and efficient system performance.
