The Process of Manufacturing Rolled Metal Bearings Through Forging

Forging has dawned as a revolution in the metalworking industry. Offering higher tenacity and potency, forged components not only prove to be sturdy but also allow for seamless and joint-free products, bringing down disorder and malfunction  rates to negligible numbers. Moreover, it has a wide range of applications ranging from the smallest tool-box wrench to the massive space shuttles.

The process entailing pressing, pounding or squeezing of a metal, by subjecting it to high pressure environments, so as to yield highly potent components or parts is called forging. Opposed to casting, this process does not involve melting of metals to shape final products. The reason that forging is preferred over any other metalworking process is because the final products are much stronger than those produced by any other process.
The forging industry entails:

Custom Forging:

The forged parts in this vertical are made to order for the ultimate users as per their specifications.

Captive Forgings:

The units produced here are meant for the internal consumption of the company for manufacturing other products.

Catalog Forgings:

Standard products are made as resale parts.
Be it the wrench or the hammer in the tool-box or components of high precision used in the Boeing 747 or the NASA space shuttle, forged products span it all. Carbon, various alloys containing nickel, cobalt and molybdenum; stainless steel, titanium, aluminum brass and copper are the main metals used for the process of forging. Depending on the use of the produced component the metal to be forged, is decided upon.
Seamless ring rolled forgings are one of the products produced through forging. These rings are highly tensile and do have a high demand and critical applications in industries like mining, energy generation, off-highway equipment and aerospace. They vary in shapes and sizes ranging from rings for bearings to almost high walled cylinders. The smaller versions find place as pressure-resistant and torque-resistant parts in components like engine bearings in aircrafts, gears, couplings, wheel bearings, flanges, rotor spaces, value bodies and pressure vessels.
The Production Process
It begins with subjecting the circular ingot to deforming temperatures, which are different for different metals, for instance 2200 Fahrenheit for steel (1020) grade. The preheated ingot is then pierced with a punch leading to vacating the punched area and removal of the displaced metal. The shape obtained, referred to as a perform, is now ready for being ring rolled. Next, the perform is slipped into the Inner Drive (I.D.) roll and rotated with the Outer Drive (O.D.) roll pressing the perform from the outer circumference. The mandrel roll simultaneously regulates the height of the ring, giving it the desired shape.
Forging products confirm to varied standards or intensities of use conditions like low and high degree temperature performance, hardness, machinability and ductility. Therefore rings for bearings, produced through the process of forging are unmatched in strength and can be used for a wide variety of purposes.
