What is a Key?
• A key is a piece of mild steel inserted
between the shaft and hub or boss of the
pulley to connect these together in order to
prevent relative motion between them.
• It is always inserted parallel to the axis of the
shaft.
• Keys are used as temporary fastenings and
are subjected to considerable crushing and
shearing stresses.
• A keyway is a slot or recess in a shaft and
hub of the pulley to accommodate a key.
