Keyed bars, especially those conforming to din 6880, are essential components in mechanical assemblies. Primarily used to secure rotating elements, these steel bars play a crucial role in transmitting power and maintaining part alignment.

What is a keyed bar?

A key bar is a rectangular piece of metal used to lock two components together, enabling torque transmission and preventing relative movement between the parts.

Keyway bars are often made of steel and conform to specific standards, such as DIN 6880, which defines dimensions and tolerances. They are inserted into corresponding grooves in the components to be joined, ensuring a solid connection.

DIN 6880

The din 6880 standard specifies dimensions, tolerances and materials for keyway bars. This standard guarantees perfect compatibility and interchangeability in a wide range of industrial applications.

Key bar applications

Power transmission

In transmission systems, key bars are used to secure shafts to hubs or pulleys, ensuring efficient torque transmission.

Industrial machinery

Industrial machines use keybars to keep rotating components aligned and secure. They are essential for the smooth operation of gears, pulleys and wheels.

Automotive and aeronautics

In the automotive and aerospace industries, keyed bars are used in steering systems, engines and transmission systems to ensure reliability and safety.

Advantages of steel wedge bars

How to choose the right keyed bar?

To choose the appropriate keybar, it is important to consider:

  • Dimensions : The dimensions must match the grooves of the components to be assembled.
  • Material : The type of steel should be chosen according to the loads and conditions of use.
  • Standards : Make sure the bar complies with the relevant standards like DIN 6880.

Depending on the application, additional considerations such as corrosion resistance, heat resistance and dimensional tolerances may be important.

Installation of a din 6880 wedge bar

Installation Steps

  1. Preparation : Check that the grooves on the components are clean and free of debris.
  2. Inserting the Bar : Insert the keyed bar into the groove in the shaft.
  3. Assembly : Slide the hub or pulley onto the shaft, aligning the groove with the keybar.

To install a keybar, you will need:

  • Hammer : To insert the keyed bar into the groove.
  • Punch : To properly align the bar in the groove.
  • Caliber : To check dimensional tolerances.
