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. ▲ Close

MISUMI
This is the least expensive ball spline suitable for fixation using shaft holders, etc., or for incorporating into plates. This standard enables highly accurate linear motion and rotational torque transmission. In addition, the contact area between the ball groove machined into the shaft and the steel ball is large, resulting in a large load capacity and long life. Even a single axis can be used as a linear motion guide, allowing for a compact design.
A dustproof seal is attached to the nut, so the ball will not fall off even if the spline shaft is removed.Days to Ship: 8 Day(s) or more -
Ball Splines - Both Ends Stepped
MISUMI
ball spline with stepped edges on both ends. This standard enables highly accurate linear motion and rotational torque transmission. In addition, the contact area between the ball groove machined into the shaft and the steel ball is large, resulting in a large load capacity and long life. Even a single axis can be used as a linear motion guide, allowing for a compact design.
