Square Keystock

Square 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. Unlike rectangular key stock, square key stock has a square-shaped cross-section, which means all four sides are equal in width. Square key stock serves the same fundamental purpose as other key stock types: it 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 essential for maintaining alignment and synchronizing the movement of various parts within a mechanical system. Like rectangular key stock, square key stock is available in different dimensions and materials to suit specific applications. It is a critical component in machinery and equipment where precise torque transmission, alignment, and synchronization are crucial for proper functioning.
