Keyes DIN 6885 A 8x7x70

Product detailed description

The key tight DIN 6885 A 8x7x70 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 hemispherical ends, which ensures optimal seating in the groove. The dimensions of the key are 8 mm in width, 7 mm in height and 70 mm in length, which is standardized for use in various mechanical assemblies.

The material from which the key is made is C45K steel, which is a medium carbon steel with good strength and toughness, suitable for applications requiring high resistance to wear and mechanical stress. The C45+C surface treatment indicates that the material has been treated to increase strength and corrosion resistance.

This component belongs to a group of fasteners known as parallel keys, which are used to precisely and firmly connect rotating parts, allowing torque to be transmitted without the risk of displacement or loosening. Thanks to its precise dimensions and quality material, the DIN 6885 A 8x7x70 key is ideal for use in various industrial applications where high reliability and precision of the connection are required.
