Frequently Asked Questions (FAQ)
Q1: What are the main advantages of using pure copper bushings in steering systems?
A: Pure copper offers excellent thermal conductivity, self-lubrication, and corrosion resistance, reducing friction and wear. This results in smoother steering, longer service life, and lower maintenance needs compared to standard steel or bronze bushings.
Q2: Can this bushing be customized to different dimensions?
A: Yes, we can customize the outer diameter, inner diameter, and length according to your drawings or specifications. Please contact our sales team with your requirements.
Q3: How do you ensure the quality of the bushings?
A: We perform 100% dimensional inspection using precision instruments, and load testing is conducted on random samples from each batch. Our factory has been ISO-compliant (certification available upon request) and follows strict quality control procedures.
Q4: What is the packaging for export?
A: Standard export packaging includes wooden pallets or cartons, with individual bushings wrapped in oil-proof paper or plastic bags to prevent corrosion. Custom packaging can be arranged.
Q5: What is the lead time for an order?
A: For standard sizes, lead time is 15–20 days after order confirmation. For custom orders, it may take 25–35 days depending on complexity and quantity.
Q6: Do you offer samples for testing?
A: Yes, we provide free samples for qualified customers; you only need to pay the shipping cost. Samples are available within 7 days after request.
Q7: Can these bushings be used in other automotive applications besides steering?
A: Absolutely. The high load capacity and durability make them suitable for suspension systems, gearbox shafts, and other rotating or sliding components where low friction and long life are required.
Q8: Is there a minimum order quantity (MOQ)?
A: Our MOQ is 500 pieces for standard bushings. For custom designs, the MOQ may vary—please consult our sales team.
