Where Are Ball Splines Used?

In the complex world of linear motion control, the diversity and functionality of the ball spline is unmatched. Are you curious to learn, “Where are ball splines used?”

Embark on an exploration into the world of ball splines and their multiple applications, shaping innovations across diverse sectors.

Unravelling the Concept of ball splines

Ball splines, available on Matara, are an innovative type of linear motion control solution. They offer near-frictionless linear motion control while simultaneously transmitting torque. A ball spline consists of grooves along the shaft length, providing a pathway for ball bearings. The bearings reside within an outer casing known as a bushing, a vital component of the ball spline. The bushing cannot rotate around the ball spline shaft but can move freely along it.

The rotary ball spline, a more advanced version, includes a rotating element on the nut’s exterior diameter. This ingenious design allows the ball spline to control not only linear motion but also rotary motion, functioning as a blend of a recirculating linear guide and a ball screw.

When is a ball spline the best choice?

• Linear ball splines, found in our Ball spline range, are often used in dual-shaft configurations. This design prevents the bearings from rotating as they traverse the shafts. As these ball splines inherently resist rotation, they can also serve effectively in single-shaft configurations. This results in a host of benefits, such as a smaller footprint in confined spaces, lower physical weight, and an easier assembly and alignment process.
• Rotary ball splines, offering linear and rotary motion control in one, are perfect when the spline shaft must provide vertical movement and a rotary bearing is required for rotational movement.

So, where are ball splines used?

Ball splines are especially suitable for applications requiring linear motion control while maintaining a level of torque control. Below are some common applications where ball splines shine:

• Honing Machines: These precision tools for refining surface finishes and obtaining high-accuracy size elements use ball splines to ensure controlled, simultaneous handling of linear and rotational movements.
• Robotics: In this rapidly advancing field, ball splines enable complex movements, allowing robots to perform intricate tasks more efficiently.
• Oil, Gas, and Water Exploration: ball splines enable precise positioning of drills and other tools, promoting efficient extraction processes.
• Industrial Automation: In manufacturing, ball splines are valued for their precision and efficiency in automated assembly lines, reducing error margins and increasing productivity.
• Packaging Solutions: In the packaging industry, ball splines ensure quick, accurate, and repeatable movements, essential for high-speed packaging operations.

At Matara UK, a trusted manufacturer of splined shafts in the UK, we offer both linear and rotary ball spline solutions for a broad range of applications. We are proud suppliers of the complete array of TBI Motion Technologies’ ball spline series.

The salient features of the TBI ball spline range

TBI’s ball spline series, including the SLF, SLT, SOF, and SOT ranges, available at Matara, offers several unique features:

• High Load-Carrying Capacity: Every groove on a TBI ball spline shaft is precision-ground to form a perfect 40° angular contact point, enabling it to manage a greater moment load.
• Zero Angular Clearance/Backlash: TBI’s precision design ensures no clearance, making it suitable for applications requiring maximum precision.
• High Sensitivity: TBI’s unique 40° angular contact design ensures minimum friction force whilst maintaining high sensitivity and rigidity levels.
• High Rigidity: TBI ball splines combine a wide contact angle with an appropriate level of preload, providing high torque and moment rigidity.
• EZY Mount on Design: TBI ball splines demand low maintenance. The spline shaft will retain its design and shape even when the spline nut needs removal.

By understanding where ball splines are used and their advantages, industries can optimise processes and boost efficiency. Whether in robotics, industrial automation, or oil exploration, ball splines are the unsung heroes, propelling us towards a future of greater precision and capabilities.
