Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export sales of US$5-10 million and a global reach spanning North America, Europe, Asia, Africa, and Oceania. Our Pure Copper Bushing for Marine Propeller Shafts (100mm OD x 60mm ID) is engineered to deliver exceptional corrosion resistance and dimensional stability in the harshest marine environments. Manufactured from high-purity copper, this bushing ensures reliable performance, reduced wear on propeller shafts, and extended service life—backed by a 1-year warranty that reflects our commitment to quality.
Key Features & Benefits
- Premium Pure Copper Construction – Made from C1100/C1020 grade copper with ≥99.9% Cu content, offering excellent thermal conductivity and natural lubricity to minimize friction.
- Superior Corrosion Resistance – Withstands saltwater, moisture, and chemical exposure, preventing rust and pitting that could compromise shaft integrity.
- Precision Machined Dimensions – 100mm outer diameter and 60mm inner diameter with tight tolerances (typically ±0.05mm) for a perfect fit on propeller shafts.
- Enhanced Load Distribution – The bushing’s wall thickness of 20mm provides robust support, reducing vibration and noise during operation.
- Long Service Life – Copper’s self-lubricating properties reduce the need for frequent maintenance, saving downtime and replacement costs.
- Customizable Options – Available in different lengths, chamfers, or oil grooves upon request to meet specific OEM or aftermarket requirements.

Why Choose Our Bushing?
In marine propulsion systems, even minor bushing failure can lead to costly shaft repairs and downtime. Our pure copper bushing is designed to excel in continuous immersion, high humidity, and variable loads. The material’s natural anti-galling properties prevent seizing, while the precise machining ensures concentric alignment, reducing vibration and extending bearing life. Compared to bronze or brass alternatives, pure copper offers superior heat dissipation, which is critical in high-speed or heavy-load applications.

Frequently Asked Questions
-
Q: Is this bushing suitable for saltwater environments?
A: Yes, pure copper is naturally resistant to saltwater corrosion. Our bushing is specifically designed for marine propeller shafts and can withstand prolonged exposure to seawater. -
Q: Can I get custom dimensions (e.g., different OD/ID)?
A: Absolutely. We offer customization for length, outer diameter, inner diameter, and special features like oil grooves or chamfers. Please contact us with your requirements. -
Q: What is the lead time for this product?
A: Standard sizes are typically in stock and can ship within 7–10 days. Custom orders may require 15–25 working days depending on quantity and complexity. -
Q: Does the bushing require any lubrication?
A: While copper has inherent self-lubricating properties, additional grease or oil can be used for enhanced performance. The bushing can be machined with oil grooves if needed. -
Q: What is the warranty coverage?
A: We provide a 1-year warranty against manufacturing defects. If the bushing fails due to material or workmanship issues within one year, we will replace it free of charge. -
Q: How do you ensure dimensional accuracy?
A: Each bushing is CNC machined and inspected with precision measuring tools (micrometers, bore gauges). We maintain strict quality control with tolerance checks on every batch. -
Q: Do you offer samples before bulk order?
A: Yes, sample orders are welcome. We can provide a single piece or a small batch for testing. Sample cost is negotiable, and shipping is at buyer’s expense. -
Q: What is the packaging method?
A: Standard packaging is individual polybags with foam protection, then packed in cartons or wooden crates. We can also customize packaging per your instructions.
