A keyed shaft collar is a mechanical component used to fasten a rotating shaft to a stationary component, such as a bearing or a shaft-hub connection. It is designed to lock onto a shaft with a keyway to prevent slippage or rotation of the shaft collars and any attached components. The keyway is a slot or groove machined into the shaft, which allows the shaft collars to be positioned in a fixed location along the shaft. A matching key is then inserted into the slot or groove, providing a positive mechanical connection between the shaft and the shaft collars.

Keyed shaft collars are commonly used in machinery, equipment, and power transmission systems, where precise positioning and alignment of components are critical. They are easy to install and remove, and they provide a secure and reliable connection between the shaft and the shaft collar, ensuring efficient and safe operation.
