C93200 Bearing Bronze, widely recognized as SAE 660, is the premier alloy for high-performance bushings and bearings. Known for its exceptional anti-friction characteristics and superior machinability, C93200 is engineered to operate under medium-to-heavy loads while protecting shafts from premature wear.
At Standard Metals, Inc., we specifically stock Type III Continuous Cast C93200. This manufacturing process creates a highly dense and uniform grain structure, resulting in superior wear resistance and a more reliable service life compared to traditional casting methods.
Primary Compliance & Specifications
Our inventory is managed to satisfy both modern industrial and legacy military requirements:
- ASTM B505: The standard specification for Copper-Base Alloy Continuous Castings.
- QQ-C-390: Federal specification for high-performance tin-bronze and bearing-bronze castings.
- Type III (TY.III): We exclusively carry Continuous Cast material for maximum structural integrity.
- SAE 660: The primary industrial designation for this high-lead bearing bronze.
- DFARS Compliant: Sourced from the USA or DFARS-approved countries.
Advantages of Type III Continuous Casting
The TY.III Continuous Cast process used for our C93200 inventory offers distinct engineering benefits over sand-cast alternatives:
- Enhanced Material Density: The continuous cooling process produces a tighter, more uniform grain structure throughout the cross-section of the bar.
- Consistent Mechanical Properties: Provides predictable hardness and strength from the surface to the core, ensuring reliable performance after machining.
- Optimized Machinability: The uniform structure allows for higher machining speeds and a smoother surface finish, critical for achieving tight bearing tolerances.
Core Engineering Advantages
- Natural Lubricity: The high lead content provides a natural antifriction surface that helps protect the system during start-up or in the event of temporary lubrication gaps.
- Conformability: C93200 can slightly deform to accommodate minor shaft misalignments, preventing localized stress and scoring.
- Wear Resistance: Ideally suited for applications involving sliding friction, oscillation, and heavy load-bearing requirements.
Common Industry Applications
- Heavy Equipment: Main bearings, sleeve bearings, and thrust washers.
- Marine Systems: Pump liners, fuel pump bushings, and steering gear components.
- Hydraulics: Cylinder liners, guide bushings, and hydraulic press components.
- Automotive: Specialized fittings and high-wear sleeve bearings.
