Key Parallel

DIN 6885A is a standard for parallel keys used in mechanical engineering. These keys are used to connect rotating machine parts, such as shafts and hubs, in order to transmit torque and prevent slipping.

The DIN 6885A standard specifies the dimensions and tolerances of these keys. It also provides guidance on the selection of key sizes based on the diameter of the shaft and the type of connection required.

The key has a rectangular cross-section and is inserted into a keyseat on both the shaft and the hub. The keyway is cut perpendicular to the axis of the shaft, providing a snug fit that prevents slipping.
