Anping County Boli Hardware Wiremesh Products Factory (established in 1998) presents our precision-engineered Copper Bushing for Hydraulic Cylinder — a critical component designed to withstand extreme loads and harsh operating conditions. With an inner diameter of 50mm, outer diameter of 60mm, and length of 20mm, this bushing delivers reliable performance in demanding hydraulic systems. Backed by over 25 years of manufacturing experience and annual export value exceeding US$5 million, we ensure each bushing meets rigorous quality standards for industrial applications worldwide.
Key Features & Technical Benefits
- High Load Capacity: Engineered for heavy-duty hydraulic cylinders, capable of handling radial loads up to 100 MPa without deformation.
- Premium Copper Alloy: Manufactured from C86300 (manganese bronze) or C93200 (bearing bronze), offering excellent wear resistance and low friction coefficient.
- Precision Dimensions: ID 50mm (±0.025mm), OD 60mm (±0.030mm), Length 20mm (±0.1mm) — ensures perfect fit in standard cylinder housings.
- Enhanced Lubrication: Optional oil grooves or graphite plugs reduce maintenance frequency and extend service life.
- Corrosion & Heat Resistance: Suitable for operating temperatures from -40°C to +250°C, ideal for both hydraulic oil and water-based fluids.
- Customizable Finish: Surface roughness Ra 0.8–1.6 μm available, with tighter tolerances upon request.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this bushing?
A: The copper bushing can perform reliably in temperatures from -40°C to +250°C. For extreme heat above 250°C, we recommend consulting our engineering team for material adjustments. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer sample orders. Please contact us with your delivery address, and we will provide a quotation including shipping cost. -
Q: What is the typical lead time for 500 pcs?
A: For standard dimensions (50mm ID, 60mm OD, 20mm length), lead time is 10–15 working days. Custom dimensions may require 20–25 working days. -
Q: Do you provide dimensions with oil grooves or graphite plugs?
A: Yes, both options are available. Please specify your requirements (e.g., number of grooves, depth, or graphite plug diameter) when ordering. -
Q: Is this bushing suitable for use with water-glycol hydraulic fluids?
A: The C86300 alloy offers good corrosion resistance in water-based fluids. However, we recommend testing under your specific conditions or using a tin bronze alternative for high-water content systems. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 100 pcs for stock dimensions. For custom sizes, MOQ may be 200 pcs. -
Q: How do you ensure the bushing fits tightly in the housing?
A: We control the outer diameter tolerance to h6 (ISO standard) and provide a press-fit recommendation. If you need a specific interference fit, please share your housing ID tolerance and we can adjust. -
Q: Can you provide a certificate of material analysis?
A: Yes, a material test certificate (MTC) is available upon request at no extra cost for orders above 500 pcs.
