13 best linear motion ball screws
Linear motion ball screws are crucial components used in machinery and equipment for converting rotational motion into linear motion. They are commonly employed in various industries, including manufacturing, automation, robotics, and aerospace, among others.
Here are some key points about linear motion ball screws:
Functionality: A ball screw is essentially a threaded rod with ball bearings (also known as ball bearings) that travel along the helical grooves of the screw. When the screw rotates, the ball bearings move, allowing the nut (which holds the bearings) to move along the length of the screw.
Precision and Efficiency: Ball screws are valued for their high precision and efficiency in converting rotational motion to linear motion. This makes them essential in applications where accuracy and reliability are paramount.
Advantages Over Other Mechanisms: Compared to other methods of achieving linear motion, such as belts and pulleys or lead screws, ball screws are often preferred for their higher load capacity, reduced friction, and increased efficiency.
Applications: They are used in a wide range of applications, including CNC machines, 3D printers, medical devices, semiconductor manufacturing equipment, and various automated systems.
Components: A ball screw system typically consists of the ball screw itself, a nut, and often a support bearing system. These components work together to ensure smooth and precise linear motion.
Types of Ball Screws:
- Ground vs.Rolled Screws: Ground ball screws are manufactured with high precision through a grinding process, resulting in a smoother surface and higher accuracy. Rolled ball screws are made through a rolling process and are generally less expensive but slightly less accurate.
- Single Nut vs. Double Nut: Some ball screw systems have two nuts that run along the same screw. This configuration provides better load distribution and can help prevent backlash.
Maintenance: Proper maintenance is essential to ensure the longevity and performance of ball screws. This may include regular lubrication and checking for wear and misalignment.
Availability: Linear motion ball screws and related components can be found through various suppliers and manufacturers specializing in linear motion products, power transmission products, and industrial scientific equipment.
Please note that my knowledge is based on information available , and we do not have access to real-time or updated information beyond that date. If you're seeking the most current details on linear motion ball screws, we recommend consulting reputable manufacturers or suppliers in this field.

| Question: | One set of 2 ball screws |
| Answer: | no, one screw and one nut so 2 parts, its called a matched set or a set. |
| Question: | Is it possible to get with motor mount (threaded) on both ends and use 2 BK12 mounts |
| Answer: | It would probably need to be special ordered or purchased else where. I know they are made. my cnc table kit from pdjinc who make the Pilot Pro CNC kit machine.. Phil the owner would know. came with them. |
| Question: | is the diameter on the other end of the ballscrew (1605) also 10mm/1cm |
| Answer: | Both ends have a 10mm diameter, so if you want a coupler for this ball screw, it will have to be 10mm on one side and your motor shaft diameter on the other. |
