Keyes DIN 6885 A 8x7x90

Product detailed description

The DIN 6885 A 8x7x90 key is a precision engineering component designed for reliable torque transmission between the shaft and the hub. This type of key meets the standards DIN 6885 A, ISO 773 and ČSN 022562, which guarantees its compatibility and standardization on an international scale. The key has dimensions of 8 mm in width, 7 mm in height and 90 mm in length, while its ends are rounded, which reduces stress concentration and improves the distribution of forces during torque transmission.

The material used to manufacture this key is C45K steel, which is known for its high strength and wear resistance. C45K steel is an unhardened carbon steel that offers good machinability and is suitable for applications where high strength and toughness are required. The C45+C surface treatment provides additional corrosion protection and improves the aesthetic properties of the component.

This key is classified as a fastener and belongs to the group of parallel keys used in various industries, including mechanical engineering, automotive and equipment manufacturing. Its precise dimensions and material properties ensure reliable and efficient torque transmission, contributing to the smooth operation of mechanical systems.
