Challenges with C85400 Bronze Bushing

Engineers choose our C85400 Bronze Bushings because we deliver reliable, problem-solving performance—not just metal parts.

  • Rapid Wear
    C85400’s high lead content provides natural lubricity, reducing friction and extending service life under light to medium loads.
  • Lubrication Failure
    Our graphite-plugged C85400 bushings offer true self-lubrication. Even during dry runs, the graphite layer protects against seizure.
  • Non-Standard Sizes
    We manufacture custom C85400 bushings to any specification—from small 10 mm IDs to large 2000 mm OD centrifugal cast rings.

Specific Applications of C85400 Bronze Bushings

Thanks to its excellent castability, airtightness, and corrosion resistance, C85400 Bronze Bushings are widely used across multiple industries:

  • Fluid Control Equipment:
    Valve stem nuts, pump housing bushings, and impeller wear rings due to their good corrosion resistance.

  • General Machinery:
    Lightweight conveyor roller sleeves and guide bushings for packaging machinery.

  • Automotive & Hardware:
    Bushings for automotive components, decorative flanges, and connector parts.

  • Home Appliances:
    Bearings used in low-speed components such as washing machines and fan motors.

  • Large Custom Equipment:
    Using our centrifugal casting technology, C85400 bushings are applied in large-scale hydraulic and water conservancy equipment as sealing rings and support sleeves.

Deep Dive: C85400 (CuZn33Pb) Material Overview

Understanding the core properties of C85400 Bronze Bushing material helps you choose the right alloy for performance and cost.

1. Composition & Core Characteristics

C85400—also known as CuZn33Pb or CC754S—is a Leaded Yellow Brass alloy.

  • Copper (Cu): 65–68%

  • Zinc (Zn): Balance, adding strength and affordability

  • Lead (Pb): 1.5–3.8%, the key to exceptional machinability

Free-Cutting Benefit:
Its higher lead content gives C85400 superior machinability. This produces excellent surface finishes, allows precise tolerances, and lowers friction against mating shafts—making it ideal for bushings requiring accurate geometry.

2. Choosing C85400 vs. Other Alloys

Expert Recommendation

Choose C85400 if you operate under light-to-medium loads, need tight machining precision (such as sealing grooves), or want a cost-effective material for atmospheric or fresh-water environments.

Choose Aluminum Bronze when equipment requires maximum strength—such as crushers, marine wear parts, or high-impact industrial machinery.

Specialized Focus: Water Conservancy & Hydropower Solutions

One of the most critical applications for our C85400 production line is in Hydraulic Engineering. Large-scale dams, turbines, and pumping stations present a unique set of challenges where standard steel fails.

Why C85400 for Water Projects?

  1. Cost vs. Scale: When manufacturing a sealing ring with a 1.5-meter diameter, the raw material cost of Tin Bronze or Aluminum Bronze can be astronomical. C85400 offers a significant cost reduction without sacrificing performance in fresh water (river/lake) environments.

  2. Corrosion Resistance: Unlike steel, CuZn33Pb does not rust. It resists bio-fouling and oxidation in aqueous environments.

  3. Complex Geometry: Turbine seals often require “Labyrinth” designs. The superior machinability of C85400 allows us to turn these complex grooves with high precision on our vertical lathes.

Key Water Components We Manufacture:

  • Turbine Sealing/Wear Rings: Reducing leakage between the runner and the casing to maximize efficiency.

  • Sluice Gate Guide Bushings: Supporting the rollers on large dam gates.

  • Impeller Mouth Rings: Sacrificial wear parts for large agricultural irrigation pumps.

The “Underwater” Upgrade: Solid Lubrication

In water conservancy, greasing is difficult (and environmentally hazardous).

  • The Fix: We drill pockets into the C85400 matrix and press-fit Solid Graphite Plugs.

  • The Result: A maintenance-free bearing. Graphite does not wash away like grease. It provides permanent lubrication even if the gate sits idle for a dry season and suddenly needs to open.

Manufacturing Capabilities: Large Scale & Precision

We are not just a stockist; we are a precision manufacturer.

1. Centrifugal Casting Technology

For bushings larger than 100mm, we utilize centrifugal casting.

  • The Science: Molten metal is poured into a spinning die. High G-force pushes impurities to the center (which are machined away) and compresses the metal grain.

  • The Benefit: A denser, stronger bushing free of porosity (air bubbles) or sand inclusions. Strength is increased by 15-20% over sand casting.

2. CNC Precision Machining

  • Equipment: Large Vertical Lathes (VTL) and 4-axis CNC centers.

  • Features: We machine oil grooves (Figure-8, Double Loop), oil holes, flange radii, and complex steps.

  • Tolerance: IT6 – IT7 precision grades available.

3. Production Capacity

  • Inner Diameter (ID): 10mm – 1800mm

  • Outer Diameter (OD): 15mm – 2000mm

  • Length: Up to 1500mm

  • Shapes: Straight bushings, Flanged bearings, Split (half) bearings, Spherical bearings.
