How to Select The Right Ball Screw For Your Automation Machine
Updated: 1 hour ago
Choosing a suitable ball screw directly affects the stability, accuracy and service life of your automation machine. There are several key factors you need to evaluate before placing your order.
1. Load capacity
Calculate the actual axial load applied on the ball screw during operation. The rated dynamic load of the ball screw must be higher than your working load to guarantee long service life.
2. Stroke and screw length
Define the maximum moving stroke of your equipment. The total screw length should reserve extra space for mounting ends. We can process ball screws to your custom length requirements.
3. Required precision grade
Select C3 ground ball screw for ultra-precision positioning, or C5 rolled ball screw for standard automation applications.
4. Rotating speed and duty cycle
High continuous speed will affect heat generation and service life. High-speed applications need proper preload and lubrication design.
5. Mounting configuration
Different end support designs, such as fixed-supported or fixed-fixed mounting types, change the maximum allowable rotation speed and rigidity.
6. Preload requirement
Preload eliminates backlash, which is essential for machines requiring high positioning repeatability.
If you are unsure about parameters, you can send your machine specification sheet or drawings to our engineering team. We will recommend the most suitable ball screw solution for your automation equipment.
