Better gears through better steel

We have spent years continually developing and testing our materials, developing in-depth knowledge about product and material characteristics that affect gear life. We use advanced steel characterization tools that help us determine how to extend that life and reduce manufacturing costs.



Using TimkenSteel product can help you take advantage of power density principles. This can happen by reducing the weight of your components and/or increasing the amount of torque or load. Ultimately, our cleaner steel, chemistry control and product consistency contribute to better gear products by:

  • Increasing the amount of load through your gears, leading to more power-dense designs
  • Increasing legislative-mandated fuel efficiency and greenhouse gases through smaller gears (the ability to downsize)
  • Reducing your total supply chain cost by decreasing manufacturing and processing costs
  • Improving distortion control
  • Achieving better fatigue resistance by reducing bending, rolling and sliding fatigue
  • Increasing expected product life by minimizing cracking and spalling

Two industry publications recently featured articles on TimkenSteel’s gear advancements. Here’s what Today’s Motor Vehicles had to say about our broaching work:

“After optimizing the material heat treatment that TimkenSteel had been supplying for an alternative that was better suited for the broaching process, the customer started getting 3,000 pulls from each broaching tool. Per-part costs on the finished transmission ring gears went to $2 from $6.”
