Keyes DIN 6885 A 4x4x25

Product detailed description

The DIN 6885 A 4x4x25 key is a precision engineering component designed for reliable torque transmission between the shaft and the hub. This 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. This standard guarantees precise dimensions and material quality, which is key to its functionality in mechanical assemblies.

The dimensions of the key are 4 mm x 4 mm x 25 mm, where the first two values represent the width and height, and the last value is the length of the key. The key has hemispherical ends, which facilitates its assembly and disassembly in the grooves of the shaft and hub. This shape also contributes to the even distribution of stress during torque transmission.

The material from which the key is made is C45K steel, which is a medium-carbon steel that provides an optimal combination of strength and toughness. C45K steel is heat treated to increase mechanical properties, which ensures long life and wear resistance.

The key is classified as a connecting material, specifically as a parallel key, which is used in various industrial applications where it is necessary to ensure a solid connection between rotating components. Thanks to its precise dimensions and quality material, it is suitable for use in demanding conditions where high reliability and accuracy of mechanical energy transmission are required.
