Keys

100 years of key manufacturing expertise

A key is a mechanical part used to connect two rotating elements, such as a shaft and a pulley or gear. The purpose of a mechanical key is to : 

  • Secure two rotating parts together.
  • Transmitting torque from shaft to hub.
  • Prevent parts from slipping.

Keys come in a variety of forms: 

Keys play a crucial role in a variety of industries, guaranteeing a reliable and durable connection between mechanical components. 

These small, often overlooked but essential parts are designed to ensure a solid connection between two elements, such as shafts and hubs, in a machine or mechanism.

The 2 main key families

Parallel key - din 6885 a-form key

The form a or standard key are among the most popular models. 

Rectangular in shape, they fit into specific grooves, making them easy to assemble and disassemble. These keys are widely used in sectors such as mechanical engineering, drive technology, transmission technology and many others.

Each type of key meets specific needs and offers solutions adapted to different mechanical requirements.
