Everything You Need To Know About Splined Shafts

November 08, 2021

Are you planning to use spline shafts for your project but are unsure of their capabilities? Here's a complete guide that will help you understand everything about splined shafts.


A splined shaft is a cylindrical shaft with teeth or ridges cut into it. The teeth or ridges create channels that allow the shaft to be fixed to another rotating part, such as gears, pulleys, gears, etc. These are designed to transmit power smoothly without any vibrations. These shafts are the most suitable way to transfer the torque to other mechanical devices.


What Materials Are Used To Make Effective Splined Shafts?


Here are some materials that are commonly used in splined shafts:


Carbon Steel


Carbon steel is one of the most commonly used materials for the production of machine shafts. Carbon steel is often chosen for this application because it can withstand high rotational forces. It is also cheaper than other materials, which implies that the cost of upkeep is lower.


Stainless Steel


Stainless steel is perfect for splined shafts because it is durable, has a variety of grades to choose from, and is pretty affordable. It does not corrode or rust over time, and stainless steel can withstand a wide range of temperatures while it is highly wear-resistant too. The different grades of stainless steel offer varying levels of hardness.


Alloy Steel


Alloy steel combines the best properties of several materials such as iron, nickel, carbon, chromium, etc. Therefore, it's conveniently heat-tolerant and has good durability, making it a good choice for splined shafts.


Application of Splined Shafts


Spline shafts are required in different applications such as the ones listed below.




The splined shaft is a component that can be found inside different types of vehicles. Splines create an interlocking connection and are used to transmit power from an engine to a drive axle. It is fitted with teeth designed to mesh with corresponding teeth on the other end, i.e. the drive hub.




Airplane engines may turn one or more gears which are connected with a series of splined shafts that deliver torque and power to their various components. The spline shafts can conveniently handle high rotation speeds and deliver torque.


Ships and Nautical Vehicles


The use of engineered shafts is common in ship engine design. These are sometimes used in conjunction with gears to transmit torque from one component to another. Spline shafts are often used in ship engines. They minimize the chances of misalignment with other parts.
