Keyes DIN 6885 A 6x6x80

Product detailed description

The DIN 6885 A 6x6x80 key is a precision engineering component designed for reliable torque transmission between the shaft and the hub. This type of key is manufactured according to the DIN 6885 A standard, which is equivalent to the international standard ISO 773 and the Czech standard ČSN 022562. The key has rounded ends, which allows for better stress distribution and reduces the risk of stress concentration on sharp edges, thereby increasing its service life.

The technical parameters of the key are as follows: width 6 mm, height 6 mm and length 80 mm. The material from which the key is made is C45K steel, which is known for its high strength and wear resistance. C45K steel is a carbon steel with a carbon content of approximately 0.45%, which gives it a good combination of strength and toughness. The C45+C surface treatment means that the key has been cold rolled and then normalized, which improves its mechanical properties.

The key is classified as a fastener and belongs to the group of parallel keys. Its rounded ends without holes allow for easy installation and removal, while ensuring a solid connection between components. In practice, these keys are used in various mechanical assemblies where it is necessary to ensure a solid and precise connection, such as in gearboxes, clutches or other rotating mechanisms.

This component is ideal for applications where high precision and reliability of the connection are required, while its design and material properties guarantee a long service life even under difficult operating conditions.
