13 best linear motion ball splines
Linear motion ball splines are mechanical components used in various industrial applications to provide linear motion and guidance. They are a type of linear motion guide designed to facilitate smooth and precise linear movement. Here is what you need to know about linear motion ball splines:
Purpose: Linear motion ball splines are used to convert rotary motion into linear motion. They are often employed in machinery and equipment where controlled and accurate linear movement is required, such as CNC machines, robotics, and automated manufacturing systems.
Design: A linear motion ball spline typically consists of two main components: a shaft and a housing. The shaft contains a series of grooves, and the housing contains recirculating ball bearings. The balls run within the grooves, allowing the shaft to move linearly within the housing while maintaining a high degree of precision and low friction.
Linear Guidance: The recirculating ball bearings inside the housing ensure that the shaft moves smoothly and precisely along the desired linear path. This provides excellent guidance and minimizes friction, resulting in efficient linear motion.
Load Capacity: Linear motion ball splines are designed to handle varying levels of load capacity, depending on their size and construction. They are capable of supporting both axial and radial loads, making them suitable for a wide range of applications.
Accuracy: These components are known for their high precision and accuracy. They offer repeatability and tight tolerances, making them essential in applications where consistent and reliable linear movement is critical.
Sealing and Protection: Many linear motion ball splines come equipped with seals and protective covers to prevent contamination by dust, debris, or liquids. This helps to extend the lifespan of the components and maintain their performance.
Variety of Sizes: Linear motion ball splines are available in various sizes and configurations to suit different applications. The choice of size depends on factors such as load requirements and available space.
Installation: Proper installation and maintenance are essential to ensure the long-term functionality of linear motion ball splines.This includes regular lubrication and inspection to prevent wear and maintain performance.
In summary, linear motion ball splines are vital components in industrial settings where precise and controlled linear motion is required. They offer high accuracy, load-bearing capacity, and durability, making them valuable in a wide range of applications within industries such as manufacturing, automation, and robotics.

THK AMERICA INC
Product description
The Ball Spline is an innovative linear motion system in which balls accommodated in the spline nut transmit torque while linearly moving on precision-ground raceways on the spline shaft. Unlike the conventional structure, a single spline nut can provide a preload with THK's Ball Spline. As a result, the Ball Spline demonstrates high performance in environments subject to vibrations and impact loads, locations where a high level of positioning accuracy is required or areas where high-speed kinetic performance is required. The Ball Spline provides a high degree of safety and long service life.
- With Model LT or Medium Torque Type Ball Spline, the spline shaft has two to three crests on the circumference, and along both sides of each crest, two rows of balls are arranged to hold the crest so that a reasonable preload is applied.
- This model has a large load capacity in the radial and torque directions. Since the contact angle is large and an appropriate preload is given, high rigidity against torque is achieved.
- The rows of balls are held in a special resin retainer incorporated in the spline nut so that they smoothly roll and circulate. With this design, balls will not fall even in the nut is removed from the spline shaft.

User questions & answers
| Question: | Do you sell one that is 1200mm-1500mm long? If so what price |
| Answer: | https://3dprinterwiki.info/wp-content/uploads/2017/01/Resin-MSDS-Report.pdf |
| Question: | How much does it travel with one turn of the handle |
| Answer: | IF the UV light can reach all of he resin then you might be able to. The biggest issue with this is it adheres to surfaces it cures on very well. I have to use risers on anything that has much surface contact to avoid sticking to the build plate. |
| Question: | would this be sturdy and without play enough to be used as z axis on a 3hp cnc wood router |
| Answer: | I use a hand held UV light and out a bit of the resin as the glue then hit it with the UV light and it sets right up. binding the pieces to each other. sometimes you might need to add a couple more layers curing each one but it works well for me. |
