  • Norms : Make sure that the bar complies with relevant standards like DIN 6880.

Specific considerations for H9 steel

For applications that require high precision and increased strength, H9 steel keybars are an excellent choice. Their dimensional tolerance and mechanical properties make them ideal for harsh industrial environments.

Installing H9 steel keybars

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.

Application case studies

Examples of successful use

Numerous companies in the manufacturing, automotive, and aviation industries have shared stories about the effectiveness of H9 steel keybars in their daily operations.

Business testimonials
