Keys and feather keys for shafts

Keys and keyseats for shafts are mechanical elements designed to secure the connection between a shaft and an attached part and to transmit torque. They are inserted into grooves on shafts and corresponding parts, thereby creating a rigid mechanical connection.

The operating principle of keys and keyseats is based on the mutual seating of shaped parts in the grooves, which allows the transmission of force and at the same time determines the position of components relative to each other. These elements are a common part of designs where a reliable mechanical connection of rotating components is required.

When using keys and keyseats it is usual to consider the shape of the groove, assembly procedures and material properties so that the joint meets operational conditions and design requirements. The description in this category is general and does not include specific dimensions, standards or manufacturers.
