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

It comes in various forms, such as Disc key, the Straight end key or even 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?

The parallel key is the most popular and most used key model.

It has a rectangular body that fits into specific grooves. Parallel keys offer ease of assembly and disassembly. This allows them to be used in various sectors such as the mechanical industry, drive technology, transmission and many other areas.

What is an AB key?

Norms and standards for a din 6885 form AB parallel key

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

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

Key standards reflect 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 AB keys

In 90% of cases, the keys are made of carbon steel, stainless steel, or aluminum alloys, but in case of specific needs, we can manufacture custom keys in specific materials.

  • carbon steel : very resistant but likely to rust.
  • Stainless steel : resistant to corrosion but more expensive.
  • Aluminum alloys : lightweight but less resistant than steel.

Process for manufacturing AB shaped keys

  • Drawing, rolling and shot blasting: cold processing of steel to obtain the final section.

  • Cut: cutting the key to the desired length and shape.

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

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

  • Some text processing
    • 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: shipping to the customer according to the agreed terms.

Tips for choosing the right key

Selection criteria

  • Type of load : dynamic or static.
  • Material : corrosion resistance, weight.
  • Dimensions : compatibility with existing components.

Mistakes to avoid

  • Neglecting tolerances.
  • Choose a material that is unsuitable for assembly.
