As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Pure Copper Bushing 50mm Outer Diameter, 30mm Inner Hole, 0.05mm Runout, 200°C Working Temperature. This bushing is engineered to deliver exceptional performance in demanding industrial applications. With a pure copper construction, it offers superior thermal conductivity, corrosion resistance, and durability. The tight tolerance of 0.05mm runout ensures precise alignment and minimal vibration, while the 200°C working temperature capability makes it suitable for high-heat environments. Whether you need replacements for heavy machinery or custom components for new equipment, our bushing is a reliable choice.
Key Features & Technical Specifications
- Material: 100% pure copper (C1100 or equivalent) – excellent electrical and thermal conductivity, naturally antimicrobial, and resistant to corrosion.
- Outer Diameter: 50mm ±0.1mm – precisely machined for a snug fit in housing bores.
- Inner Hole Diameter: 30mm ±0.05mm – smooth bore for shaft rotation with minimal friction.
- Runout (TIR): ≤0.05mm – ensures concentricity, reducing wear and noise in rotating assemblies.
- Working Temperature: Up to 200°C continuous – maintains mechanical integrity under high thermal stress.
- Surface Finish: Ra ≤1.6μm – polished surface reduces friction and extends service life.
- Hardness: As per pure copper standard (HB 35-45) – soft enough to conform to slight misalignments, yet durable.
- Customization: Length, groove, oil holes, and chamfer options available upon request.

Advantages & Customer Benefits
- Enhanced Equipment Lifespan: The high precision (0.05mm runout) reduces vibration and uneven wear, prolonging the life of both the bushing and the mating shaft.
- Heat Dissipation: Pure copper’s excellent thermal conductivity (≈400 W/m·K) efficiently transfers heat away from friction points, preventing overheating in high-speed or heavy-load applications.
- Corrosion Resistance: Copper naturally resists corrosion from moisture, oil, and many chemicals, making it ideal for harsh environments like mining, marine, and chemical processing.
- Noise Reduction: The smooth surface and tight tolerances minimize noise and rattling, contributing to a quieter operation in machinery.
- Customizable Dimensions: We can adjust length, add lubrication grooves, oil holes, or keyways to match your specific design requirements.
- Cost-Effective: As a direct manufacturer with 25+ years of experience, we offer competitive pricing without compromising quality.
Frequently Asked Questions (FAQ)
-
Q: What is the difference between pure copper bushings and bronze bushings?
A: Pure copper bushings offer higher thermal and electrical conductivity, while bronze (copper-tin alloy) provides greater hardness and wear resistance. Our pure copper bushing is ideal for applications requiring superior heat dissipation and corrosion resistance, such as in electrical equipment or high-temperature environments. For extreme mechanical loads, we also offer bronze bushings upon request. -
Q: Can this bushing be used for food processing machinery?
A: Yes, pure copper is naturally antimicrobial and safe for incidental contact with food. However, we recommend checking local regulations. The bushing can be supplied with a food-grade lubricant if needed. -
Q: What is the typical lead time for custom orders?
A: For standard sizes (50mm OD, 30mm ID), we have stock and can ship within 7-15 days. Custom orders (different length, grooves, etc.) typically require 15-30 days depending on quantity and complexity. -
Q: How do you ensure the 0.05mm runout tolerance?
A: We use high-precision CNC lathes and conduct 100% inspection with a CMM (Coordinate Measuring Machine) to verify runout. Each batch comes with a test report upon request. -
Q: What is the maximum operating temperature for this bushing?
A: The bushing can operate continuously at 200°C. For short-term peaks, it can withstand up to 250°C, but prolonged exposure beyond 200°C may cause oxidation. -
Q: Do you provide samples before bulk order?
A: Yes, we offer samples. For small quantities, a sample fee applies but is refundable upon bulk order. Lead time for samples is about 5-7 working days. -
Q: Can I get a coating or plating on the bushing?
A: Yes, we can provide tin plating, silver plating, or other coatings for improved solderability or corrosion resistance. Please specify your requirements. -
Q: What packaging do you use for export?
A: We pack each bushing individually in plastic bags, then in foam-lined cartons or wooden pallets for sea/air freight. Custom packaging (e.g., blister packs, shrink wrap) is available upon request.
