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.
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.
Our selection of parallel key
A drilled key is a standard key with one or more through-holes. These holes are used to fasten the key to the shaft or to the mounted element using screws or pins.
Drilled keys are often used in applications requiring additional fixing to prevent axial movement of the mounted element. They are commonly used in machines where high torque forces are present.
A tapped key is similar to a drilled key, but the through-holes are threaded to accept screws. This makes for an even more secure and robust fastening.
Tapped keys are used in applications where a very secure fastening is required. They are common in heavy equipment and systems where reliability and robustness are crucial.
Shapes and dimensions
Drilled and tapped keys are similar in shape to standard keys, but with through holes or threads. Dimensions vary according to industry standard specifications and application requirements.
Materials used
These keys are generally made from carbon steel, stainless steel or aluminum alloys. The choice of material depends on wear and corrosion resistance requirements.
Characteristic comparison
The main difference lies in the through-holes. Drilled keys have unthreaded holes, while tapped keys have threaded holes for screws.
Application comparison
Drilled keys are used for standard fastenings, while tapped keys are preferred for fastenings requiring increased security.
Industrial sectors
These keys are used in a wide range of industrial sectors, including automotive, aerospace, machine building and energy. Their versatility makes them suitable for a wide range of mechanical applications.
Machine types
These keys are found in electric motors, compressors, transmission equipment, and various other types of industrial machinery. They are essential for ensuring a solid, reliable connection.
Flexibility of use
Drilled and tapped keys offer great flexibility in terms of fastening, allowing easy and secure installation.
Reliability
Thanks to their robust design, these keys ensure efficient torque transmission and reliable fastening, even under difficult operating conditions.
