Ball Screws

Get efficiency and precision with the right industrial ball screws for your application requirements
By Ydalia Tolentino Ball screws provide a very efficient means of converting rotary motion to linear motion or vice versa. Due to a ball screw’s high reliability, you can use it for many applications like machine tools, handling equipment, automation and others.
 

Basically, a ball screw is a power screw which consists of the following components: a screw, a nut and a set of small balls on a track that rotate in the groove between the screw and nut. The manufacturing processes used for these screws are rolled, milled and ground. Ball screws also come in various materials that include steel, titanium and bronze.

Certain physical specifications are necessary in selecting a screw’s application design requirements. Some of the important parameters to consider when choosing industrial ball screws are:

1. Review carefully your particular design requirements and specification factors like design arrangement (English/Metric), outer diameter and length of screw, screw lead accuracy, static load capacity, life expectancy and various others before you purchase industrial ball screws.

2. Find ball screw manufacturers who carry specialty ball screws for your application needs.

3. Ensure your business keeps running smoothly by getting quality ball screw repair services.

• There are many formulas and calculations needed for accurate selection of ball screws. A useful and simple one is for lead (axial distance a nut travels in one revolution of a screw). The formula is Lead = Pitch x Start where the Pitch is the axial distance between threads and the screw Start is the number of independent threads on the screw shaft.
