Precision Ball Screw

 

Precision ball screws are precision components for mechanical transmissions. They utilize rolling friction instead of sliding friction to reduce friction and thus increase transmission efficiency and accuracy. The following provides a detailed introduction to precision ball screws, including their basic structure, operating principle, advantages, and application areas.

Key Specifications to Consider for Ball Screws

When selecting a ball screw for your precision engineering needs, several key specifications must be taken into account: 

 

Lead and Pitch of Ball Screws

The lead is the distance the nut travels per screw revolution, while the pitch is the distance between adjacent threads. For high-precision applications, opting for a smaller lead and pitch can enhance accuracy, albeit potentially at the cost of speed.

 

Diameter of Ball Screws

The diameter of the ball screw impacts its load capacity and rigidity. A larger diameter generally means greater load-bearing capabilities and less deflection, essential for maintaining precision under heavy loads.

 

Load Capacity of Ball Screws

Load capacity is a critical specification, determining how much weight the ball screw can handle without compromising performance. Both dynamic and static load ratings should be considered to ensure the ball screw can sustain the forces during operation.

Accuracy Grade of Ball Screws

Ball screws come in various accuracy grades, denoted by classes such as C0, C3, or C5. Higher accuracy grades (e.g., C0) provide superior precision but are more expensive. The choice depends on the specific requirements of your application.

 

Backlash in Ball Screws

Backlash refers to the slight movement that occurs when reversing the direction of motion. In high-precision applications, minimizing backlash is crucial to maintaining accuracy. Look for ball screws with preloaded nuts to reduce or eliminate backlash.

 

Material and Coating of Ball Screws

The material and coating of the ball screw influence its durability and performance. Common materials include stainless steel and alloy steel, with coatings like Teflon or chromium providing additional protection against wear and corrosion.

 

Made to Your Specification

 

You are not “locked in” to a few ball screw and nut designs in a catalog. We can offer a solution that is easy to install, saving you money by minimizing the need to retrofit or adjust other components.

 

Size Flexibility and Unlimited Selection

 

Ball screw diameter and lead sizes are offered in both imperial and metric sizes. We manufacture ball screw diameters from 5/8” to 6” and specialize in long screws (the longest to date was 67 feet)

 

 

Metric Precision Ground Ball Screws

Accuracy Class: C0, C1, C3, C5
