Fundamentals Of Splined Shafts

A wide range of industries depends on numerous machines and equipment for successful functioning. In today's modernized times, having the right machines and equipment can make or break your business.


The availability of components that make up industrial machinery is also crucial to the smooth functioning of industries. Industrial machinery has many moving parts and among them, the most important ones are gears and splines that enable torque transfer.


Splined shafts are shafts with teeth or ridges. The larger surface area of these ridges enables better torque transmission compared to different gear types.



Here is everything you need to know about splined shafts.



What material is a spline shaft made of?

These shafts need to be strong and durable to offer effective torque transfer. Gear and spline manufacturers have to be careful with the material selection as entire operations can be sabotaged due to shafts of inferior quality. Here are some materials used for manufacturing these shafts.


  • Carbon steel
  • Stainless steel
  • Aloy steel


Carbon steel can withstand high rotational forces and is relatively sheep. Stainless steel does not corrode or rust and is highly wear-resistant. Alloy steel is made using materials like iron, chromium, carbon, and nickel making it extremely durable and tolerant to heat. These materials are made into splined shafts using the following methods.


  • Broaching
  • Milling
  • Hobbing
  • Extrusion
  • Shaping


Following are certain industries that rely on spline shafts.


  • Automotive
  • Aviation
  • Shipbuilding


Dependable and experienced spline and gear manufacturers like True Gear & Spline use CNC machining to offer higher quality and dependability. The state-of-the-art technology and team of skilled technicians together make sure splined shafts of only the best quality are manufactured at True Gear & Spline.
