Gardette Industries, manufacturer of parallel keys since 1925

A key is a mechanical part used to connect two rotating elements, such as a shaft and a pulley or gear, enabling the transmission of motion and force.

It comes in a variety of forms, such as the disk key, the straight-end key or the 2-round-end key.

Keys are essential in many industries to ensure a reliable and durable connection between mechanical components.

What are the different types of parallel keys?

‍Theparallel key is the most popular and widely used key design. 

It has a rectangular body that fits into specific grooves. Parallel keys are easy to assemble and disassemble. This makes them ideal for use in a wide variety of sectors, including mechanical engineering, drive technology, transmission technology and many others.

What is an AB key?

Norms and standards for parallel keys din 6885 form AB

  • Din 6885: Din 6885 specifies dimensions and tolerances for parallel keys. 
  • Form AB: This specifies the shape and machining process used to manufacture these 1 straight end, 1 round end keys. The AB shape key is characterized by its rounded edge, which reduces stress concentrations and enables better load distribution.

The AB shape key is ideal for applications where dynamic loads are present, such as in engines and gearboxes.

Key standards testify to the interchangeability and standardization of mechanical components. 

This ensures that components made by different manufacturers are compatible, which is essential for repairs and replacements.

Materials used to manufacture form AB keys

In 90% of cases, keys are made from carbon steel, stainless steel or aluminum alloys, but for special requirements, we can manufacture custom keys in specific materials. 

  • Carbon steel : highly resistant but susceptible to rust.
  • Stainless steel : corrosion-resistant but more expensive.
  • Aluminum alloys : lightweight but less resistant than steel.

Manufacturing process for AB shape wedges

  • Drawing, rolling and shot-peening: cold transformation of steel to obtain the final cross-section.

  • Cutting: cutting the key to length and shape.

  • Finishing: creating grooves, countersinks and other shapes to create a rounded and a straight edge and hold the key in position.

  • Tribofinishing: controlled wear to improve surface finish and eliminate burrs.

  • Treatmentssome text
    • Heat treatments to modify mechanical properties.
    • Surface treatments to protect against corrosion.

  • Quality: systematic control of raw materials, semi-finished and finished products.

  • Logistics and packaging: packaging and delivery planning.

  • Delivery: dispatch to the customer as agreed.

Tips for choosing the right key

Selection criteria

  • Load type : dynamic or static.
  • Material : corrosion resistance, weight.
  • Dimensions : compatible with existing components.

Mistakes to avoid

  • Neglecting tolerances.
  • Choose a material unsuitable for mounting.
