No items found.

Key steel, like those compliant with DIN 6880 standards, are essential components in mechanical joints. Used mainly to secure rotating elements, these steel bars play a crucial role in transmitting power and keeping parts aligned.

What is key steel?

A key bar is a rectangular piece of metal used to fix two components together, allowing for effective torque transmission and preventing relative movement between parts.

This key steel is manufacture to DIN 6880 standards, which lays out dimensions and tolerances. They are inserted into the corresponding slots of the components to be assembled, guaranteeing solid connection.

DIN 6880 standard

DIN 6880 defines standard dimensions, tolerances and materials for key steel. This norm allows for perfect compatibility and interchangeability in a wide range of industrial applications.

Applications for key steel

Power transmission

In transmission systems, bars of key steel are used to fasten shafts to hubs or pulleys, ensuring effective torque transmission.

Industrial machinery

Steel bars for keys are used in industrial machines to keep rotating components aligned and fastened. They are essential for the proper functioning of gears, pulleys and wheels.

Automotive & aeronautical sector

In the automotive and aeronautical industries, key steel is used in steering systems, engines, and transmission systems for maximum reliability and safety.

Advantages of steel keybars

Sturdiness & durability

Steel bars for keys are extremely sturdy and long-lasting, capable of withstanding high loads and tough operating conditions.

Precision & compatibility

Manufactured to DIN 6880, these bars offer dimensional accuracy and high compatibility, making them easier to integrate into many different mechanical systems.

Wear resistance

K9 steel bars, in particular, boast excellent wear resistance, which extends the joint's life.

How do I choose the right key steel for me?

To find the key steel you need, it is important to consider:

  • Dimensions: The dimensions must correspond to the keyways of the components being assembled.
  • Material: The type of steel must be suitable for the expected loads and conditions of use.
  • Standards: Make sure the steel bar complies with relevant standards, e.g. DIN 6880.

Depending on your desired application, other considerations may also be important, such as corrosion resistance, heat resistance and dimensional tolerances.

Installing DIN 6880 key steel bars

Install steps

  1. Preparation: Make sure component grooves / keyways are clean and free of debris.
  2. Inserting the bar: Insert the key steel into the groove on the shaft.
  3. Assembly: Slide the hub or pulley onto the shaft, aligning the groove with the key steel.

In order to install a key steel bar, make sure you have a:

  • Hammer: To insert the key steel into the groove.
  • Punch: To align the bar correctly in the groove.
  • Gauge: To check dimensional tolerances.
