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 a Form A key?

Norms and standards for parallel keys din 6885 form A

  • Din 6885: Din 6885 specifies dimensions and tolerances for parallel keys. 
  • Form B: This specifies the shape and machining process used to manufacture these straight-end keys. The Form B key is characterized by its straight ends, which reduce stress concentrations and enable better load distribution.

The Form A key is rectangular with flat edges. It is designed to fit snugly into a machined keyway on the shaft and mounted element. Dimensions vary according to industry standard specifications and application requirements.

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.

Key manufacturing materials form A

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.

Method of manufacturing form A keys

The Form A key corresponds to the standard, and is easy to manufacture and install, making it an economical and efficient choice.

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

  • Cutting: cutting the key to length and shape.

  • Finishing: creation of grooves, countersinks and other shapes to create rounded edges 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.
