Martin Sprocket & Gear 40BS24 Sprocket With Keyway

The Martin Sprocket & Gear 40BS24 sprocket with keyway is a keyed-shaft power transmission component designed for secure torque transfer in machinery that uses a compatible shaft. It features a.750 inch bore and a machined keyway that accepts a standard shaft key, allowing the sprocket to be firmly mounted to the shaft and resist slipping under load. The 40BS24 designation identifies this specific sprocket within Martin's catalog, signaling a compatible profile for automotive, industrial, and equipment drive systems that require a keyed connection. The inclusion of a keyway simplifies alignment and installation when replacing worn or damaged sprockets, helping maintain drivetrain accuracy and uptime. When selecting this part, verify that the bore size (.750 in) and keyway dimensions match your shaft and drive components to ensure reliable engagement and proper fit. Use standard installation practices and consult your system's engineering specifications—particularly shaft tolerances and key dimensions—to ensure correct seating and long service life. This part is presented as a Martin Sprocket & Gear product with the 40BS24 designation, intended for applications that require a robust, keyed connection between sprocket and shaft.
