Key bars are essential mechanical components in many industrial applications. Complying with the DIN 6880 standard, these bars are used to ensure the transmission of power and to keep the parts in place.

What is a thumb side key bar?

A key bar is a rectangular metal piece inserted into corresponding grooves in two mechanical components to lock them together, thus allowing the transmission of torque and preventing relative movement between the parts.

Key bars with inch dimensions are commonly used in countries using the imperial system. These bars must meet the inch size specifications to ensure that they fit the mechanical components properly.

DIN 6880 standard

The standard din 6880 specifies the dimensions, tolerances and materials of keybars. This standard ensures that key bars are compatible and interchangeable, ensuring efficient installation and operation in mechanical systems.

Applications of a keyway

Power transmission

Key bars are widely used in power transmission systems to attach shafts to hubs, gears, and pulleys, allowing for efficient torque transmission.

Industrial machinery

In industrial machines, key bars maintain the alignment and fixation of rotating components, ensuring smooth and safe operation of equipment.

Automotive and aeronautics

Key bars are also essential in automotive and aircraft vehicle steering systems, engines, and transmissions, where reliability and safety are paramount.

Advantages of inch side steel keybars

Complying with standards such as DIN 6880, these inch drawn bars offer dimensional accuracy and assured compatibility, facilitating their integration into various mechanical systems.

Wear-resistance

High quality steel bars provide excellent wear resistance, extending the life of the assemblies.

How do I choose the right thumb side key bar?

Selection criteria

To choose the appropriate key bar, it is important to consider:

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

In some industrial contexts, it is crucial to choose keybars with dimensions in inches to ensure compatibility with equipment using the imperial system.

Installing a thumb side key bar

Installation steps

  1. Preparation : Make sure component grooves are clean and free of debris.
  2. Inserting the bar : Insert the keyway into the shaft groove.
  3. assembly : Slide the hub or pulley onto the shaft, aligning the groove with the keybar.

To install a keyway bar, you will need:

  • Hammer : To insert the key bar into the groove.
  • Hallmark : To align the bar correctly in the groove.
  • Caliber : To check dimensional tolerances.

Case studies of applying thumb side bars
