Rectangular Keystock

Rectangular key stock, often referred to as keystock or key bar, is a type of fastener used in mechanical systems to transmit torque between a rotating shaft and a connected component, such as a pulley or gear. It is called "rectangular" because of its shape, which is typically a straight bar with a rectangular cross-section. Key stock is inserted into a matching keyway or keyseat that is machined into both the shaft and the component. Once properly fitted, it prevents relative motion between the two, ensuring that when the shaft rotates, the connected component also rotates. This is crucial for maintaining alignment and synchronizing the movement of various parts within a mechanical system. Rectangular key stock is available in different dimensions and materials to suit specific applications. It is a vital component in machinery and equipment where precise torque transmission, alignment, and synchronization are critical for proper functioning.
