Detailed Information:

At Ratna Exports, we are committed to creating unique, durable, long-lasting products that we can use in diverse industries for a long time. We ensure that our products are dimensionally accurate and offer outstanding usability, and we strive to provide the best customer service possible. To provide our clients with maximum performance, we assess them for the right product selection based on their industry needs.

Among the many aspects of what we do as a manufacturer, trader, stockist, supplier, and exporter of Rotor Shafts, we are in the business of setting up the cylinder-shaped rotary component that holds blades into place, as well as using it to produce a rotating component. Our company manufactures nickel rotor shafts for generators with high, medium, and low-pressure turbines. We also manufacture Stainless Steel Generator Rotor Shafts that are ideal for power plants because they can withstand extreme rotation and pressure levels without damage under extreme conditions.

Among the largest suppliers of Alloy Steel Rotor Shafts and machine parts, we also supply Carbon Steel Rotor Shafts to cement and mining companies for grinding and separating materials. Machine parts producers and shipbuilders also require Carbon Steel Rotor Shafts. Electric motors are built with rotor shafts, which sit on top of the laminated core of the rotor and act as the transmission shaft through which the torque is transmitted from the electric motor to the rotor via the positive connection associated with the transmission system. It is a necessary component of any electric motor. Aside from the requirement for bearing the rotor and its various attachments, the design of the rotor shaft is also very important regarding its cooling concept, in addition to the requirement for bearing the rotor. Additionally, the design of the rotor shaft is highly dependent on the choice of cooling concept used for the electric motor. Designing new cooling and lightweight components with hollow shafts as electric motors grow larger and longer, as well as rotor shafts that are larger and longer, makes it easier to design both new and lightweight components with hollow shafts. 

Due to the high rotational speed and high torque that rotor shafts produce up to 20.000 rpm, they are subjected to extremely high load conditions. However, the transmission is one of the most crucial components of the vehicle that transfers torque from electric to kinetic energy so that it can move the vehicle. It meets these requirements and is necessary to design light and strong components.

  • Splines can be varied according to customer requirements
  • Development expertise and prototype production

Uses Of Forging Shaft 316/ 316L

Once the rotor is in service, it becomes more apparent how critical it is that the part is highly durable, and its strength and reliability become paramount. In some of the applications that a rotor shaft often finds itself in, whole cities can rely on the part, whether it be for water or a hydro application.

SS 316 Or 316L Shaft

To decide which is better, either SS 316 Shafts or 316L  Stainless Steel Shafts, you need to consider the use of the shaft. SS 316L is a material that has a higher melting point, which enables it to be used in applications at elevated temperatures. In contrast, 316 SS has better corrosion and chemical resistance properties. On the other hand, their strength is remarkably similar. If you need shafts for general purposes that are affordable and that are of high quality, then 316L SS shafts are a good choice. However, 316 ss shafts are a better choice if you intend to use them in marine or chemical environments.
