Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
C95400 aluminum bronze (ASTM B148)
Aluminum bronze sand casting; verify composition, as-cast or heat-treated condition and mechanical properties against ASTM B148 and the drawing.
C93200 leaded tin bronze (SAE 660)
Leaded tin bronze bearing material; verify composition and properties against the applicable standard and supply condition, and maintain the lubrication specified by the equipment design.
C54400 Phosphor Bronze
Wrought leaded phosphor bronze; verify properties and load requirements against the product form, supply condition and drawing.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Gear mesh forces cause uneven bushing wear, with one side wearing faster than the other.
- Inadequate lubrication causes direct metal contact between the bushing and journal, producing heat and seizure.
- Extended operation enlarges the bushing bore and gear mesh clearance, increasing noise and vibration.
- Contaminated lubricant causes scoring on the bushing surface.
Replacement criteria
Check bushing bore wear and clearance against the maintenance limits for the model. Inspect the bushing if abnormal gear noise persists after adjustment, and replace it if seizure marks or extensive scoring are present. Check the gear tooth contact pattern after replacement.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
C95400 aluminum bronze (ASTM B148), C93200 leaded tin bronze (SAE 660), or C54400 phosphor bronze
Heat Treatment Condition
Follow the applicable standard for the material grade; confirm heat treatment and hardness requirements against the drawing
Composite / Hardfacing Requirements
Bronze bushings are not suitable for weld overlay repair. Replace the worn bushing as a complete part; surface repair is not recommended.
Dimensions and Inspection
Manufacture to drawings produced from part measurements or supplied by the customer. Critical mating surface tolerances follow OEM requirements. Use UT/MT inspection to assess castings for shrinkage porosity and cracks against the agreed acceptance criteria.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
