Keyes DIN 6885 A 20x12x90

Product detailed description

The DIN 6885 A key with dimensions of 20x12x90 mm 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 ISO 773 and ČSN 022562 standards, and is characterized by rounded ends (semi-round).

The key material is C45K steel, which is an unalloyed structural steel with a carbon content of approximately 0.45%, which provides good strength and wear resistance. The C45+C surface finish indicates that the key is calibrated and has increased dimensional accuracy, which is important for precision engineering applications.

The key is included in the group of parallel keys, which are used for a rigid connection of rotating parts, ensuring torque transmission without the risk of slipping. Dimensions of 20 mm (width) x 12 mm (height) x 90 mm (length) are standard for this type of application, while the rounded ends make it easier to assemble and disassemble the key from the groove.

This component is suitable for use in various industrial sectors where it is necessary to ensure a solid and reliable connection between the shaft and the hub, such as in mechanical engineering, the automotive industry or in the field of machinery and equipment manufacturing.
