Ball Splines

Sometimes a standard product isn't the right fit. When your specifications and parameters exceed what off-the-shelf solutions can offer, THK provides customization options to maximize your efficiency and performance.

Our linear motion solutions are engineered to deliver smooth, accurate movement while minimizing maintenance requirements and enhancing overall system performance. Wh... Read more...

The Isotech Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability. Read more...

Today, semiconductor manufacturing equipment is essential for the production of all kinds of electronics.

Ball splines are versatile linear motion systems, ideal for applications such as SCARA robots, pick-and-place operations, and more. Offering greater design flexibility, ball splines do not require a horizontal base like linear guideways. As a superior alternative to bushings, HIWIN ball splines and nuts are crafted from the same high-quality materials as HIWIN’s ground ballscrews a... Read more...

The SPLFS Type is a spline with little dynamic friction resistance and its outer diameter is approximately 20% less than conventional types – a significant space saving. Because all components are made of stainless steel, SPLFS Type ball splines are suitable for high temp, clean room, and vacuum environments.

Available in 16 standard and customizable shaft size... Read more...

NB Ball Splines have no backlash because precisely ground (not drawn) raceways conform to the shape of the ball in the nut and shaft so opposing raceways have the same angles of contact. The spline shaft is straighter than the competitions - eliminating rotational vibration. Endlessly adaptable to high load linear motions.16 standard and customizable shaft sizes with diameters from 4mm t... Read more...

The rigidity of a linear system must be taken into consideration when it is to be used in high-precision positioning devices or high-precision machinery. Preloaded slide guides and ball splines, which use balls as the rolling elements, are available upon request to meet the need for greater rigidity. If a force is applied to the ball elements without preload, an elastic deformation propo... Read more...

NB ball splines are comprised of a shaft and nut assembly. Ball spline shafts feature raceway grooves. Nut assemblies consist of an outer cylinder, retainer, side rings and ball elements. This type of configuration offers many advantages, including:

• Reliably smooth motion with specially designed spline nut and shaft
• High load capacity and long travel life are...
