Centrifugally Cast Spider Bushing

Mining and materials-handling operators often must reduce raw material sizes to create something sellable. Breaking down hard aggregates into fine end products requires extreme force, which puts crushing machinery components under duress. 

Enhance heavy equipment performance and longevity with spider bushings from U.S. Bronze Foundry & Machine. With a century of experience, we have the expertise and equipment to produce large, heavyweight centrifugal and static castings for applications that power, protect, and connect our world.

What’s a spider bushing? 

Spider bushings are pivotal to the operation of gyratory crushers, which are machines that crush minerals between a hollow body and eccentrically mounted cone set on a revolving shaft. The spider bushing is responsible for supporting the top of the shaft. 

Friction, stress, age, heat, and other factors can cause spider bushings to wear, leading to gyratory crusher malfunction or inoperability. Avoid unwanted downtime by obtaining high-quality spider bushings from U.S. Bronze Foundry & Machine. 

Your spider bushing source

U.S. Bronze Foundry & Machine is a single-source supplier of spider bushings to clients operating crushing machinery worldwide. All metal casting process steps, from mold-making and liquid metal pouring to precision machining and inspection, are performed in-house under the supervision of a quality-focused management team. 

Our specialized equipment can produce spider bushing using centrifugal and static casting techniques. Built-in automation and controls ensure heightened precision and quality. 

While we can manufacture complex, homogenous metal products of any size, our area of expertise is producing large items. Our capabilities include: 

 

  • Castings up to 35,000 pounds
  • Lengths of up to 80 inches for centrifugally cast spider bushings
  • Outside diameters as large as 158 inches for centrifugally cast spider bushings
  • No size limit for statically cast spider bushings

 

An onsite machine shop enables us to deliver finished castings with precise dimensions, removing time-consuming secondary processing steps from client supply chains. The shop contains advanced CNC equipment capable of machining workpieces with: 

  • Outside diameters of 150 inches
  • Lengths of 80 inches 
  • Tolerances are +/- .001 inches

Let’s make your spider bushings today

Good foundry practice depends upon manufacturing processes and quality controls that produce conforming castings consistently. At U.S. Bronze Foundry & Machine, we’re quality conscious.

It’s a top priority to supply parts that exceed applicable industry standards or customer requirements on time, every time. Our team can turnaround rough parts as quickly as two weeks and finished pieces as fast as eight weeks, depending on lead time and other factors.

High-performance applications require quality materials 

For most applications, characteristics of the material used to make the finished part are the difference between success and failure. By combining years of experience with advanced equipment, we can make spider bushings from an array of alloys

  • Bronze And Highly Leaded Bronze
  • Copper
  • Stainless Steel
  • Aluminum 
  • Nickel  

Stainless steel spider bushings offer corrosion resistance and high strength in a lightweight package. We can work with other alloys upon request.
