High-Performance Centrifugal Cast Bronze Bushings
Product Description
Yile Machinery is a premier manufacturer of custom bronze bushings and sleeve bearings, engineered for superior performance and extended wear life. By combining the metallurgical advantages of centrifugal casting with precision CNC machining, we produce bearings that outperform standard sand-cast or continuously cast alternatives in demanding industrial applications.
The Centrifugal Casting Advantage: Unmatched Quality & Strength
The manufacturing process is the single most important factor in the performance of a bronze bushing. Unlike other methods, centrifugal casting uses rotational force to forge a metallurgically superior component.
During the process, molten bronze is poured into a rapidly rotating die. The immense G-forces:
Force the denser molten metal to the outer wall, creating an extremely dense, fine-grained structure.
Push lighter impurities, gas pockets, and porosity to the inner bore, where they are later removed by machining.
The result is a bearing blank that is free of defects and possesses significantly higher mechanical strength, durability, and load-bearing capacity.
Benefits of Our Centrifugal Cast Bushings:
Superior Wear Resistance: A dense, uniform grain structure lasts longer under heavy load and friction.
Higher Mechanical Strength: Increased tensile strength and fatigue resistance prevent cracking and deformation.
100% Defect-Free Material: No hidden porosity or inclusions that could lead to premature failure.
Material Expertise: The Right Bronze for Your Application
While we can produce bushings from any bronze alloy, our primary material for general-purpose bearings is Tin Bronze C93200 (also known as SAE 660 Bearing Bronze) . This alloy is the industry standard for a reason, offering an excellent combination of:
High strength and hardness.
Excellent anti-friction and wear properties.
Good machinability for creating features like oil grooves.
We also have extensive experience with other alloys for specific needs, including Aluminum Bronzes (for high strength) and Manganese Bronzes (for high-impact loads).
Precision Machining for a Perfect Fit
A superior casting is only the first step. Our state-of-the-art machine shop turns bronze blanks into finished, ready-to-install components. Our capabilities include:
CNC Turning & Boring to tight tolerances.
Milling of flats, keyways, and other features.
Drilling of mounting holes and lubrication points.
Grooving for oil or grease distribution (e.g., spiral, figure-eight, circular).
Manufacturing of flanged bushings, thrust washers, and complex bearing designs.
Common Applications
Our custom bronze bushings are trusted in a wide range of heavy-duty equipment:
Construction & Heavy Equipment: Excavator and bulldozer pivot points.
Mining & Aggregate: Cone crusher eccentric bushings and socket liners.
Hydraulic Cylinders: Rod glands and piston bearings.
Industrial Machinery: Presses, gearboxes, and stamping equipment.
Marine: Rudder and propeller shaft bushings.
