Ball spline series

Ball spline series

Optimal for a mechanism that performs linear motion while transmitting torque.

The ball spline is a revolutionary linear motion system that allows torque transmission while a ball, incorporated into the spline nut, moves smoothly in a straight line along the rolling surface of a precisely ground spline shaft. Moreover, unlike conventional structures, it provides preload with a single spline nut, enabling high performance in harsh applications where vibration and impact loads occur, in areas requiring high precision positioning, and in situations demanding high-speed motion performance. Additionally, when used as a substitute for linear bushes, it has a rated load that is several times greater than that of the same shaft diameter, allowing for a compact design. This makes it usable even in cases where overhang loads and moments are applied, resulting in high safety and long lifespan.

Retainer-type ball spline SLS/SLF model

Retainer-type ball spline SLS/SLF model

The SLS/SLF type, which expands THK's technology and know-how into retainer technology for ball splines, has made its debut.

The SLS/SLF shape enables the adoption of ball retainers, allowing for aligned circular motion and high-speed response. It also eliminates collisions and mutual friction between the balls, achieving low noise, good sound quality, and low dust generation. Improved grease retention has also made long-term maintenance-free operation possible.

Ball screw and ball spline

Ball screw and ball spline

Reasonable prices, extensive production range, high rigidity through preloading management.

■Reasonable Price We are working to reduce manufacturing costs with state-of-the-art equipment, and we are further striving to cut costs based on a mass production system for similar products. ■Wide Range of Production With a standard production shaft diameter of Φ140 and a diverse range of standard lead specifications, a wide selection of combinations of shaft diameter and lead is possible. ■High Rigidity through Preload Management By designing the gap between the ball and the groove to be extremely small and applying preload, we can achieve zero backlash. Additionally, by managing the amount of preload, we can obtain rigidity according to specifications. ■Support Unit Inventory We have a large stock of dedicated support units. ■Smooth Operation and High Efficiency Due to low friction resistance, smooth rotation is achieved, resulting in high mechanical efficiency with low torque, as shown in the diagram below.

Custom Gear Manufacturing Case Study [Angular Spline for Machine Tools]

Custom Gear Manufacturing Case Study [Angular Spline for Machine Tools]

Manufacturing corner splines capable of withstanding a maximum rotation speed of 20,000 rpm with gear drive.

This is a square spline for machine tools. The size is φ50, and the material is SCM, which has been subjected to carburizing and quenching as heat treatment. This square spline is used in the spindle that rotates the tool shaft of machine tools. In recent years, DD motors have generally been used for machine tool spindles, but gear drive is necessary for spindles that require cutting force and rotational torque. Therefore, a square spline capable of gear drive has been adopted. This product has a proven maximum rotational speed of 20,000 rpm, achieving high precision in gear grinding to reduce vibration and noise, as well as high precision in coaxiality through cylindrical grinding. Additionally, through our machining technology, we have achieved a fitting accuracy of within 5μm for the male and female spline parts, allowing for smooth sliding. At OJIC, we are capable of producing high-precision products like this one, based on the technology and know-how we have cultivated over 70 years. By achieving high-precision machining in this product, we prevent noise issues related to backlash and maintain the accuracy of the machining equipment equipped with this gear.

Ball spline

Ball spline

Large load capacity, zero clearance in rotational direction, high performance, high rigidity, and easy assembly.

Features of Ball Splines High Load Capacity Ball splines utilize precision-ground rolling surfaces with a 40° Gothic arch contact angle, resulting in a significant load capacity for both radial loads and rated torque due to the increased contact angle. Zero Play in Rotational Direction The spline shaft and spline outer cylinder consist of a contact angle of 40° with two-row and four-row ball arrangements. By properly adjusting the pre-load, the play in the rotational direction can be reduced to zero, enhancing rigidity. High Performance The ball in the raceway is composed of unique contact points, providing high rigidity along with high performance and low friction for energy savings. High Rigidity The raceway has a large contact angle (40°), which allows for high rigidity. Additionally, by applying appropriate pre-load, excellent torque rigidity and moment rigidity can be achieved. Ease of Assembly Thanks to a special design, the balls do not fall out even when the spline outer cylinder is removed from the spline shaft. This makes assembly, maintenance, and inspection easier.
