Ball Spline

Our Ball Spline is a high-precision linear motion component that combines rotary and linear movement within a single compact structure, offering outstanding performance for applications requiring torque transmission with axial motion. Designed with precision-ground grooves on the spline shaft and matching recirculating ball elements inside the spline nut, it enables smooth, synchronized motion with minimal backlash and exceptional responsiveness. Manufactured from high-strength alloy steel and treated with advanced heat treatment and surface hardening processes, our ball splines offer excellent durability, wear resistance, and load-bearing capacity. The rolling contact of the balls significantly reduces friction, resulting in high efficiency, low energy consumption, and minimal heat generation. This makes the system ideal for high-speed and continuous-operation environments such as robotics, semiconductor machinery, pick-and-place systems, and precision assembly equipment. Our ball splines feature excellent torque transmission capabilities, enabling the shaft to rotate under load while simultaneously moving in a linear direction. With high torsional rigidity and precise alignment, they ensure reliable and accurate motion even under dynamic conditions or high-speed operation. The compact design and high integration capability allow for easy installation in space-limited equipment, and multiple nut types (straight, flange, rotary) are available to suit different mounting requirements. Additionally, optional support bearings and end machining services allow for plug-and-play assembly. Our ball splines are available in various accuracy grades, preload levels, and shaft diameters to meet a wide range of design and performance demands. Optional features such as anti-corrosion coatings, grease-retaining seals, and maintenance-free configurations are also offered to enhance product lifespan and reliability in harsh or cleanroom environments. Whether for applications that require synchronized multi-axis movement, precision alignment, or high-speed operation with torque transmission, our ball spline systems deliver unmatched performance, stability, and versatility. With strong technical support and customizable OEM/ODM services, we provide tailored solutions that help improve efficiency, reduce machine footprint, and enhance mechanical system reliability. Choose our Ball Spline for compact, efficient, and accurate motion control in your next-generation automation systems.

A ball spline is a mechanical linear motion component that enables both rotational and linear movement while maintaining high torque transmission. It consists of a grooved shaft (spline shaft) and a matching ball spline nut that contains recirculating ball bearings. These bearings roll along the grooves of the shaft, reducing friction and ensuring smooth, precise motion in both directions.
Ball splines are ideal for ball spline applications where torque must be transmitted during linear motion—such as in robotics, automatic assembly machines, pick - and - place systems, and precision medical equipment. Unlike standard splines or linear guides, a ball spline combines load - bearing linear motion with the ability to transmit high torque, even under high - speed or oscillating conditions.

Due to the rolling contact of the balls, ball splines offer low wear, long life, and minimal backlash. The compact design allows for space - saving installation, and the high load capacity ensures reliable performance under dynamic operating conditions. Ball splines can also be configured with features such as ball spline bearing, rotary encoders, or anti - rotation mechanisms for complex motion systems.
Ball splines are available in a variety of sizes, preload levels, and materials including carbon steel and stainless steel. They are typically precision - ground for high accuracy and may be treated with surface coatings for corrosion resistance or improved durability.
