Spline Shaft

A spline shaft is a mechanical component designed to transfer torque between two rotating parts while allowing for linear motion or axial displacement. It features a series of ridges or teeth, called splines, along its length. These splines mesh with corresponding grooves in a mating component, such as a gear or coupling, enabling efficient torque transmission while permitting movement along the shaft's axis. Spline shafts are commonly used in various applications requiring precise torque transmission and axial movement, including automotive transmissions, industrial machinery, robotics, and aerospace systems. They offer advantages such as improved power transmission efficiency, reduced backlash, and enhanced load-bearing capacity compared to other shaft coupling methods, making them essential components in many mechanical systems. To select a spline shaft from MISUMI, determine the required specifications such as length, diameter, spline type, material, and any additional features. Then, use MISUMI's online catalog or contact direct our MISUMI for assistance.
