C93800 Bronze Bushings

C93800 Bronze Bushings

Self-lubricating bronze bearings are engineered for applications where external lubrication is impractical. Solid lubricants are compressed and molded directly into the bearing to guarantee a maintenance-free product. No additional lubrication is necessary.

C93800 high-leaded tin bronze bushings with precision-engineered surfaces for industrial durability and low friction

C93800 high-leaded tin bronze bushings are a cornerstone of industrial applications where durability, low friction, and corrosion resistance are paramount. At BronzeOilless.com, we specialize in delivering precision-engineered C93800 bushings tailored to meet the unique demands of your machinery.

What Makes C93800 Bronze Bushings Unique?

C93800 (SAE 67) is a high-leaded tin bronze alloy renowned for its exceptional machinability, wear resistance, and self-lubricating properties. Its composition balances copper (Cu), lead (Pb), tin (Sn), and other elements to optimize performance under heavy loads and low-speed conditions.

C93800 High Leaded Tin Bronze “SAE 67” Chemical Composition (ASTM B505/B505M-23)

Element Cu Pb Sn Zn Fe P Ni/Co
% Range 75-79 13-16 6.3-7.5 ≤0.8 ≤0.15 ≤1.5 ≤1.0

Notes:

  • High lead content (13-16%) reduces friction and enhances self-lubrication.
  • Tin improves hardness and corrosion resistance.

C93800 vs. Other Bushing Materials

To understand why C93800 is a preferred choice, let’s compare it to common alternatives:

Property C93800 (High-Leaded Tin Bronze) SAE 660 (C93200) Aluminum Bronze
Lead Content 13-16% 6-8% 0%
Machinability 80 (Excellent) 70 (Good) 30 (Poor)
Load Capacity High Moderate Very High
Corrosion Resistance Good (anti-acid) Moderate Excellent
Self-Lubrication Superior (due to Pb) Moderate Poor

Key Advantages of C93800:

  1. Self-Lubricating: Ideal for applications where external lubrication is impractical.
  2. High Machinability: Reduces manufacturing costs and time.
  3. Anti-Acid Properties: Resists corrosion in harsh chemical environments.

Mechanical & Physical Properties

C93800 bushings excel in demanding conditions due to their robust mechanical profile:

Mechanical Properties (ASTM B505)

Tensile Strength Yield Strength Elongation Hardness (BHN)
25 ksi (172 MPa) 16 ksi (110 MPa) 5% 55

Physical Properties

Melting Point (Liquidus) Density Thermal Conductivity
1730°F (943°C) 0.334 lb/in³ 30.2 Btu/sq ft/ft hr/°F

Applications of C93800 Bronze Bushings

C93800’s unique properties make it ideal for high-stress, low-speed environments:

  1. Heavy Machinery:
    • Hydraulic cylinders, excavator pivot points.
    • Why? Handles shock loads and resists wear.
  2. Marine Equipment:
    • Propeller shafts, rudder bearings.
    • Why? Excellent corrosion resistance in saltwater.
  3. Automotive Systems:
    • Steering linkages, suspension bushings.
    • Why? Self-lubricating for reduced maintenance.
  4. Industrial Pumps & Valves:
    • Why? Withstands abrasive slurries and acidic fluids.
