Custom Cast Bronze Bushings & Bearings
Product Description
Yile Machinery is a specialized manufacturer of custom cast bronze bushings and sleeve bearings for a wide range of industrial applications. We leverage advanced casting and precision machining techniques to produce durable, high-performance sliding bearings tailored to your exact specifications.
Whether you need a single replacement part for a critical piece of machinery or a production run for a new product, we are your trusted source for high-quality bronze components.
Superior Manufacturing via Centrifugal Casting
To ensure maximum density, strength, and service life, we primarily utilize the centrifugal casting process.
Unlike static or sand casting, centrifugal casting spins the mold at high speed as the molten bronze is poured. This force presses the metal against the mold wall, resulting in:
A Finer, Denser Grain Structure: Dramatically improves the mechanical properties and wear resistance of the bushing.
Elimination of Impurities: Lighter elements like dross and gas porosity are forced to the inner diameter, where they are machined away, leaving only clean, solid metal.
Superior Durability: The resulting bushing is stronger and more resistant to fatigue and cracking under heavy loads.
Common Bronze Alloys for Every Application
We work with a comprehensive range of bronze alloys to match the specific load, speed, and environmental requirements of your application. Our most common materials include:
Common Name | UNS Alloy | Key Characteristics & Typical Uses |
Bearing Bronze | C93200 | The industry standard. An excellent general-purpose leaded tin bronze with great anti-friction and machinability properties. Used in pumps, machine tools, and general machinery. |
Manganese Bronze | C86300 | A high-strength, non-leaded bronze. Offers excellent load-bearing capacity and wear resistance. Ideal for heavy-duty applications like bridge bearings, gears, and crane components. |
Aluminum Bronze | C95400 | Offers high strength, and excellent corrosion resistance, especially in saltwater. Used in marine hardware, chemical processing equipment, and heavy-duty wear plates. |
Leaded Tin Bronze | C93700 | High-leaded bronze with superior self-lubricating properties, making it ideal for high-speed applications where lubrication may be intermittent. |
We can also cast other standard and custom bronze alloys upon request.
Customization & Precision Machining Capabilities
Our core service is manufacturing to your design. We can produce a wide variety of bronze components, including:
Sleeve Bushings (Plain Bearings)
Flanged Bushings
Thrust Washers & Plates
Custom-Shaped Components
After casting, our in-house machine shop uses CNC lathes and mills to finish each part to your precise dimensional tolerances. We can incorporate features such as:
Oil Grooves (straight, circular, figure-8)
Graphite Plugs for self-lubrication
Drilled Holes and Mounting Features
Industrial Applications
Our custom bronze bushings are trusted in the most demanding equipment across various industries:
Mining & Construction: Jaw crushers, cone crushers, excavators (e.g., eccentric bushings, pivot pins).
Heavy Machinery: Forging presses, stamping machines, injection molding machines.
Hydraulics: Cylinder guide bushings and rod ends.
Marine: Propeller shafts, rudder bearings, winches.
Power Generation: Turbine components, gearbox bearings.
