Keyes DIN 6885 A 20x12x50

Product detailed description

The DIN 6885 A 20x12x50 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 reduces stress concentration and improves the distribution of forces during torque transmission.

The dimensions of the key are 20 mm in width, 12 mm in height and 50 mm in length. The material from which the key is made is C45K steel, which is a medium carbon steel with good strength and toughness. C45K steel is often used in engineering for its mechanical properties, which allow for effective force transmission and wear resistance.

Form A, which is specified in the standard, refers to a high form of the key with hemispherical ends without holes. This design is optimized for applications where it is necessary to ensure a tight connection and minimize the risk of loosening under dynamic loads.

The key is classified as a fastener and is part of the parallel key group. Its use is common in various industrial sectors where it is necessary to ensure accurate and reliable torque transmission between rotating components. Due to its properties, it is ideal for applications in mechanical engineering, the automotive industry and other technical areas where the emphasis is on precision and reliability of connections.
