Frequently Asked Questions (FAQ)
- Q: What is the exact material composition of this copper bushing? A: Our bushings are typically made from C36000 (free-cutting brass) or C93200 (bearing bronze) depending on application requirements. Both offer excellent wear resistance and machinability. Please specify your preferred alloy when ordering.
- Q: Can this bushing be used in other gearbox applications besides wind turbines? A: Yes, the dimensions (120mm ID, 140mm OD, 80mm length) are common in various industrial gearboxes, conveyors, and heavy machinery. However, we recommend verifying load and speed parameters with our engineering team.
- Q: Do you provide a material test certificate? A: Yes, we can provide a mill test certificate (MTC) for each batch upon request. Please indicate this requirement when placing your order.
- Q: What is the minimum order quantity (MOQ)? A: Our MOQ is typically 10 pieces for standard sizes. For custom dimensions, MOQ may vary. Contact us for a detailed quotation.
- Q: How long does shipping take to North America? A: Standard sea freight from Tianjin or Qingdao to major US ports takes about 20-30 days. Express air freight is also available for urgent orders.
- Q: Can I request a sample before bulk order? A: Yes, we offer samples for evaluation. Sample cost is negotiable, and shipping is at your expense. For long-term cooperation, we may deduct sample cost from future orders.
- Q: Is this bushing compliant with any specific international standard? A: Our manufacturing process follows ISO 9001:2015 quality management. The dimensional tolerances comply with ISO H7/h6. We do not claim CE or other specific certifications unless explicitly agreed upon in contract.
- Q: What payment terms do you accept? A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and for established customers, other terms may be discussed.
